cylinder heads 3.0r

Postby Libertyowns123 » Thu Jan 09, 2014 9:39 am

hey, my liberty went in for head gasket surgery this week, the heads have been removed and sent, all if good besides the fact that, the head gaskets look fine only a bit warped?, does this mean by cylinder head is damaged??, if so what is the cost for a new one of these for the H6, 2006 model, 3.0r, and i did not overheat to a crazy level, it simply sent 3/4 of the way a couple of times, before i could do something about it, please let me know!!

Warped gaskets are normal, replace them. Get the heads skimmed/checked at a engine machine shop as it will help with sealing

The mechanic will normally send the heads to an engine machine shop to confirm/correct flatness - after that - all good. As KiDo mentioned of course

Out of interest, how much do they skim usually? Enough to affect compression?

Minimal, if the heads need a lot skimmed then it will affect compression but by then, the head is warped enough to be useless

That said, thicker headgasket can fix the compression
