1320 check engine for bhp loss

[Keano]

Did you ever get a compression and leakdown test done?

hi no i have never got one of those done before, i think its something i will look into though. what will this tell me?

Basically its an indication of the health of your engine... My cyclinder 2 is a little low and I think its the piston ring...

What is a normal compression number??
Below what number we know we have a problem??

120psi I believe is a real low number but its more that the compression of each cylinder shouldnt be more than 10% different from the rest.

I believe that compression of each cylinder should be within about 15psi and that % leakage should be less than about 10%


I think the lower limit is about 133psi (9.5 Bar).

9.5BAR sounds familiar
