So I need to know where to look next. I,ve done compression check and results were cylinder 1-155 3-160 5-170 7-167 2-165 4-155 6-163 8-160 this was motor warm all plugs out throttle wide open. Leak down results 100 psi primary 1-96 3-96 5-96 7-97 2-97 4-96 6-96 8-98 if I put my ear to oil fill I could hear faint air on 5,4,and 6 engine seams really tight btw this is a 62 409 QB engine maybe valve seals? Thanks
