So after the races with my boy on the type s, and cause I'm burning oil to fast and getting white smoke out the exhaust at 6000 rpm's and higher, I decided to do a compression test gotta wait 2 weaks to do the leak down as my boy who works in a shop that will do it for me for free is outta town. Anyways, here's what I did tell me if I did it wrong? Engine was at normal operating temp, removed fuel pump fuse, then removed plug from cylinder 4 screwed in compression gauge, buddy held gauge while I cranked from inside, cylinder 4 read 145psi. Replaced plug and wire, moved on to cylinder 3 and did the same thing. Cyl. 3 read 165, replaced and did other 2 cylinders the same way which all read 165psi.
