Message My car has been sitting over winter, and I'm about to take it to Chicago for a dyno tune. So I have been going through the car. I ran a cold compression test. The block is built, so this may contribute to the low numbers due to needing clearance for expansion and the rings will seal better when warm but the numbers seem really low to me. The block has 3000 miles on it.

Cyl 1: 105
Cyl 2: 105
Cyl 3: 110
Cyl 4: 105
Cyl 5: 110
Cyl 6: 105

They are pretty consistent numbers though. Maybe I'm just stressing over nothing, just wondered if anybody has seen anything like this. I'm going to put a scope down the cylinders tomorrow to check the walls.
