Picked up a 1st gen B16 with unknown history. Did a leakdown test and the results are shown on the pics. Air leaks can be heard directly out of the the exhaust ports so bent exhaust valves there. Intake side has no leaks. During the test, I had removed the oil pan to check the rotating assembly and can hear little bit of air seeping through the rings on all four cylinders. I have never done a leakdown with the oil pan off and just need to know if that slight bit of air escaping may be normal? Possibly due the rings not fully seated since the motor has been in storage for a few months? I have not removed the head yet but did look through the spark plug tubes to check for oil on piston tops. Everything looked normal including all four spark plugs. All internals are original OEM. If anyone knows for sure some leakage is normal from the rings that would save me time and money from rebuilding the bottom end. It would suck to find out the rings are totally worn once I get the head repaired and motor assembled again.
