Wow, those numbers are pretty good. Unless there are other symptoms (knocking, burning oil, not running well, etc.). If it were me, and I like the car, I would keep it. If you want to get rid of it, I don't think you need to do anything.
Needs a new head gasket, and maybe heads and pistons.
You probaby have a blown head gasket, cracked head or both. Try doing a compression test.
You've probably warped the head and therefore the motor is unable to achieve any compression due to the air escaping out. If you're lucky, it's a machining and replace head gasket; if unlucky, you've done your motor. You've most likely got a blown head gasket. This would have caused overheating as the problem began and worsened, and the no start/lack of compression now. along with head gasket check timing more than likely jumped time if the belt is still good this causes no compression
No reason to if the intake gasket is the only problem you have. If engine was running smooth and was not overheated then there is no reason to fool with the HEAD gaskets
Most likely it's caused by a damaged head gasket when the head warped. Has the engine overheated at any time in the last few thousand miles?
You will have an improvement in engine performance and an increase in compression unless the compression rings on the pistons need replacement .
because one of the head gasket is blow, or crack you have to replace both gasket and compression test the heads
White smoke from the exhaust is a sure sign of a blown head gasket. You will also be loosing coolant with no apparent leak. A compression test will verify this. A rod will knock if the bearings are worn.
Either replace the entire line, or find the break and fix it with a compression fitting.
Your engine most likely overheated
has the car been overheated?
The most common cause is an engine that overheated.
