hey i was wondering what the normal cynlinder pressure should be a a four cynlinder and do how of any website to find info or fix a low compression problem.

because i have a 1989 mazda mx6 and its only runing 25 lbs of compression per cynlinder.

Any input would be helpful and greatly appreicited.

 

It all depends on the compression ratio of the engine.

But I would say that with 25 psi per cylinder, the engine is dead.

 

thanks

 

:chuckles:
I'd be amazed if it ran.

 

Yeah mine is 220! If that tells you anything.
