As titled.

Compression test has come back and all cyclinders are pushing just past 10bar.

I had originally planned on having it done and do it as a preventative maintenance but Iím having second thoughts.

Paul the mechanic said itís totally your choice but if it was his car heíd leave it. If it isnít broke donít fix type of thing, and seeing as other problems have risen it seems sensible to leave.

Just wondering what other peopleís veiws are on this. As itís at the garage would you just bite the bullet and get it done?

Thanks, Josh

Leave it alone. Fortunately he HG is one of those things that actually can give you a warning. Unlike the vanos or rod bearings.

So vanos and rod bearings I would do as preventative.

HG I would leave.

By the way 145psi is a little on the low side but I guess the main thing is the Grouping.

If two fall and other stay up then you know there is an issue

I am now indeed.

Vanos is undergoing surgery and also the bearings with arps.

Whatís the expected Psi/bar on the s54?
