Re: '85 Short Bed 4X4
Just FYI, compression and leak down are different test to check the condition of the engines rings and valves. The leak down test provides more detail information about their condition. Again just FYI, researching each test should help you decide which is better for what you need. E.g. Leak down test can tell you that you have an exhaust valve that is leaking, needs to be fixed, however, can drive for a little while to you save money to do it. You know this because you can hear the air leaking into the exhaust, vs the intake/carb or oil pan( e.g. ring issue.).
