Compression Test Numbers
I just recently purchased a 2016 BMW 650i Xdrive Gran Coupe with 67,000 miles and the car has ran great so far with no problems! However, I wanted to perform a compression test just to see what numbers I would get.
The Results:
Cylinder 1: 160
Cylinder 2: 162
Cylinder 3: 160
Cylinder 4: 160
Cylinder 5: 180
Cylinder 6: 180
Cylinder 7: 180
Cylinder 8: 178
This is my first compression test so I'm learning as I'm going. Is the difference of psi between cylinders 1-4 and cylinders 5-8 concerning? Please if you have any thoughts or opinions I would greatly appreciate it!
