[Mk2] [Turbo] Compression test results

[Bo]

is 15bar (or 217 psi) ok? got this number on all cylinders. or the meter is faulty.
rev3 turbo with wiseco pistons and stock MLS gasket..

That's quite high, will be some serious compression ratio... but the important thing really is that they are all the same across the 4 cylinders.

Thinking of doing a compression test on my tubby soon. What's the best procedure?
Thanks

Brian at T.F.S very kndly compression tested my rev2 last week...more or less 195...200's across the board. This was done on a warm engine with throttle held open, efi fuse disabled and 5 cranks...I thought I might be getting excessive oil blowing out of the crankcase breather, so I hooked up a catch can for the journey and went for a comp test...no oil whatsoever in the catch can but the turbo IS blowing fresh oil even though the shaft doesn't have any in/out play in it at all...enough to leak out of the throttle body assembly and slightly pool on the rockerbox support bracket...with a thin 5-30 oil in it...the bov would blow oil vapour out and coat the engine bay...well that bit of it.

compression ratio has nothing to do with compression TBH



all the 3S-GTE have been quite high at around 195, 217 is very high but was this with oil dropped into the cylinder?
