STI Type uk head gasket
 

Hi there,
Can anyone please confirm the standard head gasket thickness for a 2003 sti type uk? Is it .6mm or 1.6mm?
Cheers

Dunno if this helps or just adds to confusion,

Thanks for the reply mate, it's an absolute minefield so many variations!

0.78mm standard, but thickness ultimately depends on deck height, how much skimmed off heads etc.

on a 14 year old STI I would also consider doing the bottom end bearings as I've seen it on forums a few times where someone has done headgaskets and the bottom end has gone shortly after.

And FFS please don't put standard head bolts in. Get it studded while you can. This mod alone SHOULD stop the head gasket ever going again. Agree with the bottom end too. While it's out, if only for peace of mind and longevity, get the whole engine refreshed.

False economy not to.
