Merc 3.0 compression 1-4 45,130,140,50 culprit? my guess is cylinder issue.

It will not run good seems to bog. Seems also to be running hot . Working on it for a friend . Limited tools thinking of telling them to take it somewhere else . Hate to keep doing other things when I now know the compression.

Ayuh,...... It'll Never run good with those numbers,......

The least it needs is a head job, or more likely a full on motor rebuild,.....
