So I was struggling with what I thought was a severe vacuum leak low 02 and bad idle vacuum gauge was at 12. Pulled the motor and put it on a stand to get to the bottom of it. I had done a compression test and all were at 150 except #5 it was 135.
I pulled the rockers and pressure tested the intake looking for my vacuum leak it was fine. Pressurize #5 air was spewing out the exhaust port that explains the lower compression whacked it a couple times with a hammer no change. Checked all the others they seemed fine. Off comes the intake so I can pull my head found #4 gasket pushing into the valley next time I hit it it was done.
