Default RE: How do you check for COMPRESSION?
If the engine uses 14mm spark plugs you can get a cheap compression tester at an auto supply store..Crank it with a starter...For a reference and G62 will show about 115 PSI with the cylinder dry and about 150PSI if you pour a little motor oil in the spark plug hole first...
Flipping by hand will show lower numbers...
If the engine runs well who cares ?
