Piston Rings

[mrbilly]

has anyone here replaced the piston rings on their rav. i have low compression on all cylinders and this is what i think it is. what needs to be removed. if i undo the cylinder head does the head need re skimming or just a new gasket. can it be done with engine in.

thanks

Mr Billy.Have you done this kind of thing before?

[mrbilly]

most i have done is timing belt change but i like a challenge, would it be easier to change the engine

If its the original 3SFE lump, it might be more effective/cheaper to change the engine on the assumption the whole lot is worn. (Piston rings, bore, crankshaft shells etc)
