compression test results high in one cylinder??????
« on: 28 September 2007, 19:57 »
Has anyone ever seen 250 psi in one cylinder and 140-150 in the rest. I have a 1990 1.8L 8v, engine code ABS.  Engine runs rough and sometimes I loose oil preasure after driving it hard.  Thanks for any info.

Sticky valves possibly it does seem wrong all should be near enough the same.

Probably got lost in the "Great Crash of 08
