hahah m well only one way to find out again what happened. Disassemble it againComment

That seems lean for being boosted. I guess as long as you has no knock you're fine though....Originally posted by TurboAlero View Post

You could always have a set of MLS gaskets made.... not the cheapest option but it would probably be the best.2000 Grand Am GT

Will MLS put a good "fire" ring in the gasket or will they just make it a copper composite like the other cheaper ones will offer.Lifting my front wheels, one jack at a time.Comment

If you have a good machine shops in your area they can machine your heads to accept a steel o-ring which can then be use in conjunction with a copper gasket. But honestly there are enough people making the power your are with and without boost and they do not have gasket problems. So if I were you I would be taking a second look at the head and deck surface, the assembly procedure and your tune.1993 EXT. CAB, 3.4L V6 TBI, 5spd manual. Sonoma

Yeps I have read that , but do you guys think maybe its the LIM gasket?? because as I was searchin online I saw that if you have a bad headgasket you should get white smoke or maybe the engine isn't working smooth.
Tomorrow I will do a compression test to see if all cylinders are ok.Comment

Yes it could be the LIM. They are a much more common failure on the 3X00 motors and would explain the water and oil mix.1993 EXT. CAB, 3.4L V6 TBI, 5spd manual. Sonoma

Yeah but why would his LIM fail if its obviously been replaced when he did the head gaskets.
What LIMG's are you using? Stock? plastic Fel Pro? Or PermaSeal Fel Pro metal ones?

if it is the LIM thats done for, i would say the first two would be the most likely, since i have yet to hear 1 complaint about the permaseals...Originally posted by 3400-95-Modified View PostComment

Hmm wel its a OEM headgasket kit I bought so bought at a GM dealer over hereComment

there is the problem then. all i can say is.....for the most part, the gm gaskets (on the v6) leave alot to be desiredComment

I say do a compression test, if it checks out then you didn't blow a headgasket but you blew your lower intake manifold gasket. Seems like it would be easy to do since people have so many issues with them leaking NOT under boost, you could blow them apart like crazy.
If that is the case you def want to go pickup the metal perma-seal set from Felpro and leave your headgaskets alone.
And I'd drop your boosted AFR just a bit even if your not knocking, for safety.SpudFiles

Hey dudes well it's not the headgaskets. I made a compression test and all cylinder came up to 12 bar of pressure. So next I will make a coolant system pressure test.
For the LIM gaskets I never saw metal ones you know. Bought a while back a felpro upperkit and got the plastic one same as the OEM gasket setComment
