Just a blown headgasket?

    Well I recently pieced my setup back together after blowing a headgasket. Got her started, and the breather is blowing out a little bit of white smoke (more when more throttle given) and a little out the tailpipes. Going around the parking lot I got on it, and it dogged for a second at like 3k then starting going into boost. I could practically smell coolant, and she was spitting out quite a bit more white smoke then at idle but not as bad as when it blew the headgasket. Also while warming up, my downpipe is rolling white smoke off of it.

    Is there any way that it's not the headgasket this time, since their are 2 brand new 1's installed? Maybe the intake gaskets. I could of sworn I installed everything correctly and according to the book so I dont get how my gaskets could be leaking.

    Any help is appreciated, thank you. Oh yeah, didnt check oil/coolant yet so not sure on those results, but I bet water is getting into the oil somewhere.

    I hear ya man, doing my HG's agein over the holidays.Well as fas as some smoke you should get some
    when you first start it while the old oil/coolant Etc. is burning away. Should go away after a few miles.
    You say 2 gaskest new,Replaced one?? Only one you blew,left the other?
    I hope the other one isn't giving you problems. I always replace both when doing head gaskets just
    incase,bad thing is depending on how badly one is blown sometimes a leak down/Commpression test
    may not show it in all places(Each cylinder) if the fire ring is still together.
    I would drive it around alittle more if it's not heating up,and check the oil level agein do a leak down
    if it contiues.Let us know,Take Care.

    what do you guys have for a means of tuning?

    I didint have the blowby, but put 3 sets of head gaskets on mine when i had a set of gt40s, as soon you boosted it they would pop, the deck looked good and had the heads cut and checked out, as long as i didnt put boost on it they were fine. :huh:

    what were you torqueing the intake to?

    I replaced both HG's.  I was talking to someone about Lower manifold gaskets and he said not to use any sealant.  I used a bunch of sealant on the part that touch's the head, maybe it's sucking water out right there?  Headgaskets are torqued to 70ft lbs.  Intake was torqued down to i believe 20 ft lbs. 

    I also have GT40 heads.  You guys think the headgaskets are still leaking?

    One more thing I've been reading on here. Since their is no leaking of any coolant from the head onto the ground, if it was the headgasket, wouldnt the pressure shoot out into my overflow tank, or is that just sometimes?

    Check the valves, maybe you bent one.

    If I bent a valve why would I be leaking coolant? Not putting you down, i just dont understand how that would work.

    Update.

    I changed the oil thinking maybe it was just all the coolant still in the oil. I let it warm up then I drove it and got on it a few times. There is only 1 breather and its on the passenger side, it was smoking white, but less then it was before. And white smoke is pretty much only coming out the passenger side exhaust. When it was at its worst it was much better then yesterday, but still it was smoking quite a bit, even at idle out of the passenger side tailpipe, but none really at all out of the drivers side.

    Originally the bad headgasket was also on the passenger side. But it smoked equally as bad out of both tail pipes from the rearview mirror until I shut it off.

    Is there any possibility this is a intake manifold gasket problem? Would I be able to tell if it was?

    both times ive blown mine on my stang, it ate up all the water or pushed it all out and so none ever came out of the overflow... after i stopped at least. by the time i stoped there was basically no water left...

    When u lifted off the heads, did anti freeze pour into the exhaust? Not sure of your exh. arrangement but if u fill a pipe up its amazing how long it takes to burn that stuff out! Kinda like a halloween fog machine! LOL If u have a blowby issue, could u have broken a top piston ring? I like to push the pistons around in their bore clearance and look past the piston to look for any EXTRA ring gaps that nobody wants. Especially if it was a detonation induced gasket failure. Go for a long drive if possible and get the whole exh. system hot clear to the tailpipes and see what happens.

    What headbolts are you using?

    I just replaced the Manifold gaskest (lower/upper) to no avail it seems. Although something was weird with the lower intake. More then half the bolts on the passenger side were not tight. I used a bunch of sealant that time so I figured maybe that was it, I dont know, I followed the procedures, 7, 15, then 24 ft lbs.

    I'm using stock head bolts.

    When I pulled the heads off, their was antifreeze in every cylinder on that side, and in the manifolds (going upwards). Ive driven this car quite a bit around the parking lot (big parking lot) so any coolant just sitting in their would of burned off long ago.

    85-90ftlbd on the head bolts/studs"7/16') Always use RTV on the lower,a must!

    hmm doesnt the book say 72 ft lbs?

    I just took her for a test drive with the new manifold gaskets, got on it a couple times. Came out from store I went to, puddle of antifreeze from overflow tank (vent tube from overflow). Wouldnt start (believe some cylinders are full of coolant like before).

    I think maybe the heads are warped? What gaskets do you guys recommend I use? Also the block wouldnt be cracked would it? I mean, I cleaned up cylinders (coolant) then put on new gaskets, put it back together and she ran decent besides coolant getting into the oil. Then after starting it like 5 times then taking it for a test drive she finally poops out on me.

    can go by the book,personal prefrence is 85-90ftlbs. Man,sorry to hear that dude,Yeah I would say your
    head gaskets agein if your overflow is flowing.
    I would either go with stock head gaskets,Fel-Pro 9333 PT-1,or 1011-2. Either should work well.
    most people will bash the 1011-2's but it really is in your tunning.
    I would get your heads checked first!! what is your method when cleaning the block?

    This last time I used 9333 PT-1s. I think maybe it's the heads (warped)? Cleaning the block, I didnt. Initial timing was at 10 degree's advanced and ran about 4-5lbs of boost.

    Dude, I am VERY sorry to tell you but you may have cracked a piston and or your rings. I had a similar prob with my car, i lifted the heads (gt40s) so i replaced the head gasket and it still smoked and ate up coolant and ran like shit. I finally pulled the heads off again and a friend said i needed a ring job. I finally decided to install new rings and found that they were ALL ( most of the rings) cracked and missing peices as well as number 5 piston was split in half. You may not be so bad i would make sure your heads aren't warped ( i knew mine were not since they were new ) and then go from there.

    I just dont understand how rings gone bad, or a cracked piston lead to coolant mixing in with oil. If it was burning oil then I'd be looking elsewhere. All I can think of is, A. The block B. Heads/Head gaskets C. Manifold/Manifold Gaskets

    Ok now...I have blown a few sets of these so i will pipe in here..I ran my head bolts (arp studs) the first time to 75-80 lbs and blew both sides lifting them with 10-11 lbs single t-70 302 management combo.So then i put on some 1011-2's and ran the head studs down to 100 lbs like i was told by people on this forum!! havent had a problem yet...Do you have head studs or bolts? I have had very bad luck running factory hardware on any kind of turbo engines!! Also do a compression check with all the plugs out of the engine...See what kind of variance there is..Water in the oil or vise-versa?I never got any just pressure in the coolant system under boost pulls..and i agree it takes some time to get all the coolant out of the exhaust..Longer if ya got cats on it..
