What type of compression should I be seing if it's in decent shape? | | | | | Joined: Dec 2004 Posts: 1,897 Shop Shark | | Shop Shark Joined: Dec 2004 Posts: 1,897 | I would say 125-175 psi. It is more imporant for the numbers to be close from hole to hole than it is for the actual number. If the numbers are within 10 psi, you have a great motor, if one cylinder reads 55 and the next reads 150, you will need to do some work. | | | | | Joined: Apr 2005 Posts: 1,107 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 1,107 | my 228 after 28000 miles had 95 accross the board and mine is in good shape. | | | | | Joined: Mar 2013 Posts: 176 Shop Shark | | Shop Shark Joined: Mar 2013 Posts: 176 | Thanks guys.
