What is the typical compression on a x16xe - Wet and dry?
Pretty sure my valve stem seals are gone but I wanna make sure it's not piston rings before I rip it apart
Thanks

If it goes up when wet, its rings.
Different engines will give diff readings due to how worn in and stuff.

Yeh I can appreciate that, that's why I wanted to do a wet/dry compression test.
But what's the minium - maximum psi for the engine to be classed as 'healthy'?

i looked into this and i dont think theres a specific answer. personally i would say 180 psi would be good. what you dont want is more than around 10 psi difference per cylinder iirc

Ok cheers mate and that goes for the wet & dry tests does it? Eg - 187psi dry and 197psi wet would be fine?
