How hard to fix blown head gasket?

I am having some sudden crazy issues with my wagon. I have just fixed the cooling fan. So I thought I was good for some driving. :roll:
Had a job in San Jose (I live in Oakland 45 mile drive each way) So I drive to south San Jose to buy a bass guitar cab (mesa boogie 2x15!) then on to the job in North Jose. Well I got stuck in that famous San Jose traffic and the car overheated for a while. :wink:
It kept going and the temp never got above 3/4 the way up. Made it back home that night too. Drove to band practice no problem a few nights later.
Yesterday I get in to drive downtown and it overheats super high after I am on the freeway like 5 minutes. I hear this Psshhht sound and look at my temp and its the highest I have ever seen it!
I guess that was the radiator overflow bottle getting blasted by some hot ass steam? Or maybe the radiator itself blew off steam. I get off and check the hoses thinking I blew one (even though I didnt see steam from under the hood. No blown hoses? So I cool down, fill up with straight water. Made it home by surface streets, but with the heater on full blast and the cooling fan on it was still creeping up in heat.
I popped the valv cover cap and notice a little white residue :cry:
I also see more water than normal coming out of the exhaust.
SO I am guessing head gasket or cracked head.
I pull the plugs and they all lookfine, if not a little old.
Also, and this is the weird part, its reving hell of high in idle and every other gear. In fact it was revving high yesterday before it went all nutso and overheated.

Soooo.... Is it a real bear to do the headgasket?
I've done other cars like fords and stuff.
It's basically just yank the valve cover,
yank the head,
get the head machined,
put it back with the right gasket
do the timing belt over again,
right?

    another thought, would very low tranny fluid cause overheating like this?
  • JakerJaker familEE
    Low tranny fluid will not make your engine overheat. Do you know if your rad fan is working or not? When you say it overheated after 5 minutes on the freeway, was that at highway speeds, or stop and go traffic?
  • calaverasgrandecalaverasgrande New Wagonist
    It was at nominal freeway speeds. I live literally one block off of the ramp and its a short ramp. I basically started the car, backed up went 30 yards to the freeway. Then I had to be at 55 in the next 15 seconds or so. It has been doing this thing lately where it will go quite high, like 4k before it grabs the next gear. It also idles at 1800-2000 now, when just a week ago it was idling so low you would think it would stall. Sometimes it did!

    I wonder if I was running at 4-5k when I was going 60-70 and didnt notice it? It's kinda hectic after the onramp so I wasnt paying any attention to the gauges.

    My radiator fan switch is busted so I have it wired to a switch on the dash. It wasnt working for the first 2 months I had it and that was no problem on the freeway. On city streets it was a problem!

    After reading a few threads over at red pepper racing I dont think I have any of the symptoms of a blown headgasket.
    No chocolate milk oil,
    no blue smoke from tailpipe.
    None of the plugs are fouled.

    I do lose coolant and tranny fluid at a steady rate. Also oil is always leaking out of the valve cover on the right (drivers) side. Not a lot but enough to make a mess.
    I was about to tackle that by getting a new valve cover gasket and maybe a new valve cover cap?

    I am looking at getting a new thermostat/housing/gasket. I feel like the previous owner did some silly shit with the water hoses. I can get way more cooling from the heater on full blast than I do from the radiator?
    Oh yeah, other than that, power is fine, I get speed wobbles at 85 or so before I run out of power. (bushings or shocks?)

    I feel like this high rev and the heat issue are related somehow as well.
    Shoot, this is my datsun 210 all over again. Except that one never passed smog, and this one is in reg until Jul 2011!
  • I'm betting you have a blown head gasket. Have you done a compression test?

    Air in the coolant system (or lack of coolant) can cause crazy ideling.
  • stampernstampern Senior Wagonist
    Ya, sounds like blown head gasket. If you got the motor that hot I would definitly get the head machined for sure. While you are at it - definitely do a new water pump and thermostat (even if your other one is fairly new). If it's heating up that fast, I'm suspecting something with waterpump personally.
  • calaverasgrandecalaverasgrande New Wagonist
    I dont have the stuff for a compressions test. May be a trip to kragen in the future.
    Well I just ran it for about 7-10 minutes. Didnt even get close to overheating. It did idle rather high for a while, then came back down to normal.
    There was water in the exhaust for a couple of minutes. But then it completely cleared up about the same time the idle dropped.
    I checked the top and bottom radiator hoses and they are both hot after running for a while so I think coolant is getting around.
    Hmmm. Maybe the thermostat is just old and gets stuck only sometimes? Is the heater before the thermo? I cant tell from my book.

    Oil looks fresh and peachy as heck, tranny fluid is peachy as well.
    No oil in the coolant that I can see. hmmm.
  • stampernstampern Senior Wagonist
    The heater bypasses the thermostat. Do you notice any bubbling in your overflow tank after it's gotten hot? That's usually tell tail sign of blown head gasket. There is some stuff you can buy to put in with your coolant that will turn a certain color if you have exhaust gases in your cooling system (aka from blown headgasket). This will tell you for sure. I would replace the thermo and water pump while you are in there. Less than $50 for both and will save you $$ and time in the long run especially if you don't know how long it's been since they were replaced. Might just start with thermostat and see if that clears anything up too.
  • calaverasgrandecalaverasgrande New Wagonist
    Guess I will ride my bike to kragen and check that out. Any idea what the dont pee in the pool stuff is called? And do you mean replace water pump if I redo head gasket, or just in general? IIRC I gotta futz with the timing belt when I do the water pump? and yikes, the thermo looks hard to get to.
    Oh wait, its the 4th. Doubt Kragen is open.
  • stampernstampern Senior Wagonist
    I would do the water pump while you have the head off. Gotta to timing either way - might as well just do it once. I don't know that the stuff is called. My buddy told me about it - I've never used it.
  • calaverasgrandecalaverasgrande New Wagonist
    yeah, I'd like to avoid doing a head gasket job if possible. I am not the worlds best mechanic, but neither can I afford to take it some place. So I would have to do it myself. (and hope I dont botch it!)
    Assuming I have most of the tools, what does a head gasket job cost?
    I always hear such horror stories about doing them, but it seems fairly common at the same time.
    I've also never done a timing belt/chain on an interference engine. So I am a bit skittish about that.
    I think I want to try getting the thermostat sorted and take it from there?
  • calaverasgrandecalaverasgrande New Wagonist
    Well I read some stuff on Red Pepper racing about watching for bubbles in the coolant with the radiator cap off. Well I took the cap off and started her up.
    I did see some tiny tiny bubbles. Not big ones, but a regular stream of very tiny ones. So maybe I have a minor head gasket fail? Surely it will get worse over time. Also, checked the oil, and no water in the oil. No oil in the coolant. (that I can see). So I am getting exhaust leaking into the coolant only? Or, maybe something else causes bubbles?
  • calaverasgrandecalaverasgrande New Wagonist
    Well went to two kragens and an autozone. None of them had that magic crap you use to check for exhaust gas in your coolant. Where do you get it?
    Also, I watched some vids on youtube of what bubbles look like when you have head gasket failure. They all were majorly bubbling! mine just has very tiny bubbles. Like when you are heating water on a stove and its not boiling yet but will be in a minute. So maybe I dont have exhaust coming into my coolant after all, but there is the water in the tail pipe, which disapears after it runs for a couple minutes.

    They didnt have compression test stuff for sale, butthey did have ones you can rent with a $40 deposit. I may go that route.
    Though I would rather do the thermosat ($12 with gasket) and be done with that part.
  • NastyN8sSlamvanNastyN8sSlamvan New Wagonist
    These guys already covered everything, I just wanted to chyme in about your fear of doing a headgasket... Its a honda civic. It doesn't get any easier than that. I rebuilt a motor with a Stanley 75-85pc. set and a ring compressor. if you have a 10, 12, 14, and 17mm socket and wrenches, you're fine. We're not looking at Volkswagens here...gross. lol sounds like a head gasket. Good luck!
  • BobBob Band Wagon
    Hey something like that happened tri ky wagon . I was on the freeway and then I noticed my temp gauge was 3/4 of the way up so I stopped let it cool down and did that all the way home. Then I bought the thrmostat and so far so good. But a lot of my radiator fluid can out. I'm broke right now and had to top it off with water . I get paid in two days hope its fine till then.
  • calaverasgrandecalaverasgrande New Wagonist
    I am hopin its just a thermo. I am not so much afraid of doing a headgasket, as not wanting to start down that road without pretty good evidence that it is what needs to be done.
    so far the only symptoms I got are over heating when driven (not when sitting) and some loss of coolant. The oil looks great. there arent major bubbles in my radiator.


    Lame past couple of weeks.
    Computer dies
    dog screws up a leg,
    job cuts me off
    honda starts acting lame.
    speaking of I need to look for work now...
  • You should really do a compression test, it would tell you for sure if the head gasket is good.
    Its very easy, Auto zone has a loaner tool program if you don't want to buy one(you have to leave a deposit).
  • calaverasgrandecalaverasgrande New Wagonist
    yeah, I am gonna cruise over to the one other parts store around here tomorrow, if they dont have the exhaust gas detection kit I am just gonna do the deposit thing at Autozone or Kragen for a compression tester. If that looks kosher I'll pick up a thermostat when I return the compression test rig. Maybe pick up some new plugs and shit while I am at it. The plugs I have look a bit...used.

    Part of me actually wants to just go for it with doing the head gasket. Bu then I like getting in over my head! Even if it isnt critical, this engine has low miles and is over 20 years old. May as well do what I can to keep it humming along. It does leak oil a bit so maybe a full gasket job will remedy that. If I got that shit squared I could start thinking about picking up those nice seats I saw at pick and pull. lowering the front, and...perish the thought, getting a paint job?
  • calaverasgrandecalaverasgrande New Wagonist
    here are a few shots, in chronological order of my radiator.
    161.jpg
    162.jpg
    163.jpg
    I am not seeing bubbles like they say you should see. Bout to head out (get it?) to the former Napa on High st. to see if they got the combustion gas shit. Maybe hit up retardzone on teh way back for the compression test kit.
  • calaverasgrandecalaverasgrande New Wagonist
    dude, WHAT THE HELL! :?
    How on earth do you compression test cylinder 2 and 3? I can not get the damn thing to go in straight due to the cat being right in front of the engine. (uh.. why?)
    I got 150 and 140 on 1 and 4.
    this stuff is driving me crazy.
    I tried to track down teh exhaust gas kit but all anyone has is the UV stuff for finding leaks.
    The fella at Parts Plus said he doubts I got a headgasket if myoil looks normal.
    Ugh.
  • NastyN8sSlamvanNastyN8sSlamvan New Wagonist
    did you try the new thermostat yet?
  • calaverasgrandecalaverasgrande New Wagonist
    I picked one up yesterday. It doesnt overheat at all when its just sittin. It will climb in temp slightly but never above 1/4 up. Of course I am not pushing the engine hard. I may do that today.
    I am just worried about trashing my engine if it is a headgasket prob and I pop in a thermostat and start driving around. Like right now the oil looks kosher, and I get a little water in the tailpipe.

    Ps. Woohoo, I think I may have notice coolant slowly leaking from the radiator. or it could also just be where the coolant splashes too when I have teh cap off and the fan is spinning.
    I cleaned it all up and I'll check back in a few.
    I'm gonna do the thermostat after lunch.
    I called around, is $200 normal for a machine job on a head?
  • calaverasgrandecalaverasgrande New Wagonist
    Ok wow, found one problem. Dude had a bad thermostat so bascially he skeletoned it so that the water is always going thru it. Not sure how bad that is but there are thermostat valves for a reason right?
    Well I am back to retardzone to return the compression kit.
    Finally got it to work. 150, 140, 150, 130 on 1,2,3 and 4. Not awesome but not paint the ceiling red and grey bad either. My plugs are pretty crap looking as is my PCV filter. Gonna apply my deposit towards those and get a frozen pizza. It was a mutha getting to that thermostat!
    Wow. I have done thermostats and water pumps on many cars and this one was freaking buried. My back actually is sore! Well I guess thats how they get away with such a small hoodline on these wagons!
    Funny thing is it coulda been smaller if they had stuck the cat under the car (where it belongs!).
    phew.
  • calaverasgrandecalaverasgrande New Wagonist
    Ow, well now I am seeing bubbles, and white smoke. It's like replacing the thermostat, getting new plugs and doing the compression test exacerbated the headgasket.
    Well, now with the new plugs it starts right up!
    Sheesh. I wish I had a local friend that was a honda nut. I havent ever done an engine tear down on my own. Doing that thermo was a PITA! Well, its that or sell it with a blown gasket.
  • NastyN8sSlamvanNastyN8sSlamvan New Wagonist
    Its not hard I ripped apart my first one 2 months ago. I'd buy the book, it covers most of it. Doesn't get to technical though.. it was a bit of a disappointment :S Torque specs are key
  • calaverasgrandecalaverasgrande New Wagonist
    Which book? I downloaded a manual from shweet.org but have yet to print it out (its a hundred plus pages as single PDFs!) I also got a chilton which isnt so hot, it covers 84-95 civic del sol and crx. I have another book onthe way thats 84-89 civic. Hope the narrower range will make it more useful. :?
    The exhaust gas test fluid gets here today. Though at this point I am pretty sure the headgasket is fucked. :cry:
  • calaverasgrandecalaverasgrande New Wagonist
    Okay I amlooking fro the headgasket and figuer Imay as well get the set.
    Thing is there seems to be the same 3 Fel-Pro gakset sets everywhere I look.
    HS9219PT-1
    HS9219PT-2
    HS9219PT-3
    With the first being the most expensive, the last the cheapest.
    Anyone know the difference? I cant find ANY details on what is included. Is the cheap kit just minus a few gaskets or are they all different gasket kits for different models. They all say they are from the EW1, but I am wary.
  • calaverasgrandecalaverasgrande New Wagonist
    well first day of trying to get the headgasket done. I was doing fine until I got to the throttle cable. How the hell do you detach it? My book just says, rotate the throttle wheel and detach cable. I dont see any way to free the cable there.
    So all I have gotten done is the air cleaner, the spark plugs/wires and some misc hoses.
    I would like to get the dang throttle cable off before I try removing anything larger. It is very in the way!

    ps dude there are a LOT of vacuum lines on this thing. I have never seen so many!
    I guess I will have to clean them off and number them vary carefully, there are literally dozens!
  • calaverasgrandecalaverasgrande New Wagonist
    hmmm, not so easy to get the o2 sensor off is it? Special tool? None of my books say what is up.
  • calaverasgrandecalaverasgrande New Wagonist
    finally got the exhaust manifold off. Had to unbolt the cat and the hanger that holds the exhaust pipe to the transaxle. PITA! Got all the hoses out of the way, now I just have to get the dang head/intake mani/carb off. It looks pretty heavy. I wish there was a way to take the intake manifold off but I dont see one that is easy. The bottom nuts are impossible to get to! I left the O2 sensor in the exhaust manifold. Though it made it very hard to get the shroud off.
    Back to the wagon now....
    Oh yeah, apparently the joker that last had at this engine didnt bother with putting a valve cover gasket on. So THATS why it was always seeping oil! Ugh. After I get all this done, hopefully it will be running nice and clean.
  • sixbelowsixbelow New Wagonist
    ha its funny, you are going through the same thing I am right now. MY RT Wagon had/is still having all the same issues yours is. It is always running hot/really hot when I push it or when its 85 or hotter outside, I did everything I could to fix it... I replace Thermostat 2 times, I flushed radiator and engine, I changed Coolant Temp Sensors, Even checked the EACV on the intake too, but nothing. I even changed the O2 Sensor because the ECU was throwing code 1, and as you know, it is the biggest PITA ever! Still no improvements. I even changed plugs/wires/dizzy too just in case, and even though the car runs STRONGER, it proved the headgasket was the real problem, because now with the extra heat from good sparkplugs and wires, the car is ALWAYS overheating, and I am getting EXTREME bubbles/air in the system, my overflow tank is just pouring steam and coolant out of it, so looks like I am changing the HG on Sunday. Luckily, I bought one a few months ago, just in case, along with a water pump, so I can just get it all done without too much problem.

    So if you need any tech advice or whatever, I will be right there with ya bro, hunched over the fender of a hotass wagon in the 100 degree heat of summer hatin life! lol :?
