Compression Test:

06-25-2010, 01:46 PM

Just did a compression test on 88 325is. Numbers are as follows.

6:170
5:140
4:130
3:155
2:170
1:170

Would this mean a possible bad head gasket?

It could be, or it could be bad valves or worn rings. A leak down test will help tell where the problem is.

The car makes it possible, but the driver makes it happen.
