Hello, here are my compression test results. I wanted to make sure that engine is OK before going turbo. It was running nicely before, no oil burning etc.
M52B28, stock, unopened, COLD engine, fuel disabled, thorttle wide open, all spark plugs out.
Now I am a little bit concerned with cyl. 4. What do you think ?
RESULTS:
Looks ok to me - however a hot compression test is what you'd want to do
Shouldn't it be more around 200psi on a cold unopened engine with stock compression? Maybe my compression tester is way off, but a cold test on my Euro stock compression M52B28 is normally about 200psi. Before boosting mine I think it was almost 220psi, since boosting I think it ranges from like 196 - 212psi.
