Health Compression Test Values X5M

Teh.brandon · 08-14-2019, 08:37 AM

Hey all,
I've been having a nightmare time with my X5M recently, I was wondering if any of my fellow X5M owners knew what healthy compression test values would be on our vehicles.

Thanks in advance

Generally you will have variance due to tools used, so it is more important to ensure even or close to even values across all cylinders. If that is the case, then you need to move on to cylinder leakdown testing.

Ok thanks for the information. I wasn’t sure if there was a rule of thumb baseline value range. The car in question has consistent values (with it a 5-7% difference) across all cylinders however I was hoping to compare values to a verified healthy x5m

Cheers
