check under your radiator cap for a white foamy build up. If there isn't, then its not a catastrophic failure on the hg. it might just be a case of whoever did your headgasket didnt use any sealant around the water passages. on sealant i prefer hondabond, never disappoints.

 

Hey Mike any luck with your car yet.

 

Wonder if engine builders are using the stock OEM head gasket on their engine builds??

 

+1, any idea which headgasket was used?

was the head & block resurfaced before everything went back together?

 

No I have not yet purchased a gasket yet. Yes the head was resurfaced. I was told a cometic headgasket, at least that is what I will be putting in as soon as my bud finishes a 69 gto he is working on for a friend of his.

I'll keep you guys updated when it gets all fixed, then I may just sell it who knows.

 

I would assume that no matter how well a surface is prepped for sealant, all it takes is one drop of oil, or one drop of snott falling out of a nose to land on that surface unnoticed to cause it to eventually leak. Like a chain reaction from there.

 

Sorry to hear this happened. This is one reason why I won't modify past 400awhp on my EVO. I've had many fast modified cars in the past and they all broke down at some point or another. The less you put on, the less problems you'll have.

 

good luck man it hurts to read that post..

 

yeah it hurt to post it up.Thanks

 

if you haven't pulled the head already, it would be interesting to see what the torque values are on your head studs. Just to see if they may have loosened up on you after a couple of heat cycles.

 

Yup exactly what I ill be doing this weekend to see if they are off spec or not. Head is still all on the car, man I have not even taken off a single bolt yet.

Mike

 

if was a stock motor and you found a loose head stud, I'd say tighten it back down and see what happens. But with a built motor, I don't know if I'd take that chance or not. Actually I did take that chance.... and I came out ok, but wouldn't give that advice to anyone else.

Stupid story.... Built motor in a supra, used the trip to vegas (annual event covered by Turbo Mag.) as the break-in period. When I got there, worried about too much liquid in my catch can and thought maybe I had water getting into my crankcase via the head gasket, so pulled the cams to verify the head studs were all tight, and two were only finger tight. Re-torque'd them, and everything worked out OK. Engine held together fine. Just my experience, not saying you should try it.

 

Iam going to play it safe and install a new one for piece of mind.

 

thats a good idea

 

i'm down right now for HG as well..
i was using cometic....but recently i've been hearing alot of failures ..dunno y. mine was fine for the last 2 years or so.
Heard alot of people using the original mitsubishi gasket though.
but I'm gonna be replacing my blown gasket with a greddy 1.2mm.
my head had to shave as well...just slightly...so the 1.2 should be perfect for me.
