can overheating ruin piston rings?

LambdaJoker · 05-11-2007, 11:13 PM

my car blew a headgasket due to overheating, and my mechanic is now telling that it also fried my rings. is this possible or is he just trying to get me to spend more money?? he also said that my car overheated because of a cracked turbine housing, is that also possible.

i searched and found nothing having to do with overheating ruining piston rings or a cracked turbo overheating the engine.

over heating doesnt make your rings to fry.

crack turbo housing. check it if its true.

You are wrong.
Overheating can cause ring failure and or a seized motor. If you get that oil hot enough it will break down not lubricating the cylinder walls, bearings, etc trashing them. I personally think your mechanic is screwing you, i doubt you ruined them from overheating, but i'm tired of people posting BS around the forums...

Overheated rings lose their temper, wear capabilities and spring. It depends on how badly it was overheated. If there is any discoloration on the cylinder walls, you're done.

car didnt overheat too bad. as soon as it would get over the halfway mark i would look for a gas station and turn off the car. this happened about 3 times though, but it never went past the 3/4 mark. after the third time the head gasket went out throwing out a bunch of white smoke through the muffler. turbo housing is cracked for sure, i already saw it. no discoloration on cyl. walls. so would i need to replace the rings or just a new head gasket?? nothing wrong with head neither.
