Taking my good old CMI headers off for testing, form 525's.
Don't see any issues, but if I do a compression test on the cylinders, which is a lot easier then a leak down, and the compression is OK, Can I assume that the motors are OK? Or do I have to do a leak down also to be sure that motors are OK.
Is there anythingI can discoonect on the 525 EFI's when I do the compression test so I won't get a spark?
Or just remove all spark wires.
Thx
