i have a 420a in a 99 eclipse it runs like a champ but i cant keep a headgasket in.
its got a full custom turbo setup that runs 25psi all day no eng problems but every now and then i push my head gasket out, is there anything i can do or do i just need to deal with it? thanks
 
umm.....i dont think head gaskets should be pushing in and out? maybe im just not understanding what your saying but this does not sound good.

Huh? I think that you are talking about a different gasket. If you "push" the HG "out" you must pull the head to fix. This I would consider a eng. problem. Give us a different gasket.

Pushing a hg is slang for blowing a chunk out from between the block and head. It is usually used by older people, usually drag racers.

Do you have head studs or stock chrysler head bolts? What kind of hg are you running? I would suggest arp studs and a cometic hasket. Make sure the top of the block is machined smooth along with the head surface. If it still goes, you might have a problem with detonation. I wouldnt think that low of boost would constitute o-ringing the head.
 
yeah i didn't literally blow it out. i have arp head studs but i am using the stock MLS headgesket from the factory. i cant find any after market ones!
 
THANKS! Im not very up to date on head gaskets so you all have been a big help
