Hi all,

1) what is the compression (in psi or bar) expected to be ?

2) what is the minimum it is allowed to be ?

3) if one cylinder is down a bit with respect to the other, how different can they be (i.e. 1 bar different) before it is considered an issue ?

I know the compression ratio is stated as 11.5 to 1, but wondering what a compression check reading should give, and what would be considered acceptable / problematic.

As an example, if one were showing 165 psi is that good or bad ?
Presumably this sort of info is given is a service manual somewhere, but I've not managed to find it written down anywhere.

Cheers,
John.
