1981 300SD Low compression #1 cylinder
I finally got around to checking my compression and found (the car has 300K+ miles on it) all cylinders had 280-325 on the compression EXCEPT #1 which I checked 6 times with different crush washers and could never get over 160.
I'm thinking I need to recheck my valve clearances one more time. What else can I look for to try and figure the problem?
