need some advice on what's wrong with this engine.
details:
20v silvertop

blue smoke came out only when engine at high vacuum.
ie. AFTER high rev and released the gas pedal straight away.

you tell me..
what other sources of oil will get sucked into the engine only at high vacuum. not rings or it would blow smoke under accel. you don't have a post TB turbo....
sounds like you don't want to believe

nah, i just thought that i might miss something.
i am happy that it's only the valve stem seals, not the piston rings. 
do u have any idea how much it would cost to change new seals?
Cheers,
Jin.

Is it possible to do them with the head on in this engine? If so, not very much. If not, then the head needs to come off. Exxy.
