Thanks

u have to specify

Are you looking for the Compression RATIO or the Compression PRESSURE?

@VCheng. we want to know the compression pressure not the compression ratio.

I suspected so.

I am going from memory, but the normal compression pressure for that engine should be between 175-200 psi, with lower service limits of 125 psi, and no more than 20% variation between cylinders.

Thanks for the information, my problem is the bore is slightly oversize and compression pressure now is 120 psi in each cylinder. The engine is slightly missing at intervals could be the valve problem, what do you think ?

Bore oversize is not a problem if your have properly matched oversize pistons and piston rings as well.

The slight missing could be a valve issue, yes, or even a simple electrical problem with ignition.

More details would be helpful in troubleshooting.
