To try and find the source of my turbo's oil consumption last night I started off with a compression test. (It was a bit of a disaster to say the least, the compression gauge came apart on the 2nd cylinder leaving the scew in portion attatched to the engine and inaccessible to all the tools lying around at my place. Managed to stuff my back pushing it out of the way of the other car so that I could nip over to my my father in laws to get something more suitable but in the end it came out so no damage done.)

The compression reading was 10.9kg/cm3 - is this healthy? I thought I had a note of what to hope for but can't finf it anywhere. (I know that the reading needs to be treated as suspect given the subsequent self destruction of the gauge!)

Any input would be most appreciated

Strange metric measurement but I think that's 10.9 Bar which is quite healthy.
Is this across all 4, hot or cold?

That relates to 10.68 bar or 155psi. Measurement was taken after 10 minutes running from cold. Cylinder one only as the gauge came apart on the 2nd cylinder.

I'll be retesting at the weekend but asuming similar readings, does this point to a healthy engine and unhealthy breather and/turbo?
