Re: Compression
It's really really good for an engine with 400,000kms. Congratulations. Good tough little motors, aren't they?
Mazda specifies standard compression of 192psi for a new NA6 engine, with maximum variation between cylinders of 28psi. Mazda's minimum spec is 135psi. So according to Mazda you're not needing new rings or valve seat work yet.
