heh i managed to blow out a or both head gaskets after just over 2k miles.falure ocured on my 4th 19psi run.if i switch to copper gaskets do i need to get the heads/block o-ringed. or would i be fine just droping a set on the motor as it is.or should i just get a good replacement stock head gasket set and see what happens again.

though im still not sure if i hurt anything else yet.i wont know till i get the motor apart.but im pretty sure its just a head gasket since its blowing antifreeze out the ex

 

Personally I'd get a set of felpro stock replacment gaskets with arp head bolts and try again paying closer attention to your tune. With a good tune most headgaskets will live, last season I put 220 passes on my car running between 19-26psi of boost without a failure. Took the heads off over the winter to replace worn guides and the gaskets looked like new.

If you want a stronger gasket than that try an multi layer steel gasket(like cometic).

HTH,

there is nothing wrong with the tune.and its hard to find good headgaskets,not many companys make stuff for the 60* v6 engines

 

Ive heard bad things about MLS gaskets. I picked up these for my engine.

Fel-Pro Performance Head Gaskets: FPP-17030 - summitracing.com

That was suggested by Summit's Tech Support.

 

I hope I didnt offend you but I've seen alot of good tunes burn headgaskets, pistons, ect.

Felpro 512SD Perma Torque Severe Duty are similar to what I use(only mine dont carry the severe duty tag)and with arp bolts should be just fine.

I've never personally used MLS gaskets but have heard they work from other people, I personally think the perma torque type gaskets will live in most applications. Though the factory has been using MLS gaskets lately with good results.

 

i'd look into cometics. i know guys with em on every type of forced induction possible and they hold up great. a little expensive but definately worth it.

 

I ran them with no problems on about 14-15 psi.

 

The headgaskets are a fuse . I would rather blow a headgasket that burn piston and mess up the internals. RJC and cometic make really good headgaskets ....... the problem is im sure you will need a rebuild after you blow their gaskets

 

I'm having trouble finding a site that sell cometics gaskets. Anyone have a link?

 

here is a link to the cometic site Cometic Gasket, Inc..

Its all about the tune. Ive ran my grand national @ 27psi everytime i drive the car for the last 3yrs no problems on stock headgaskets.

 

Much grass, sir.

 

You need o-rings for copper headgaskets. Either the block or heads. I have my block 0-ringed, and i havent had one problem with my car. 3 yrs of running. And i've had a few misshaps where my wastegate vacuum hose blew off and the engine saw upwards of 30lbs of boost before i noticed. Your running a 3.1? Your problem may never be able to get fixxed. It might be the design of the heads or head bolt pattern. I dont think the 3.1 is really designed to handle tons of cylinder pressure.
