Did a quick compression test today on the engine I'm planning on pulling. These are the numbers. Rather surprising. #1 Nothing! Well, I got about 10-15. Checked it a couple of times too. #2 through #5 got between 115 and 125 #6 a solid 140 What do these differences indicate? How could the first cylinder have practically no pressure? Got 14-12'' and a steady needle on the vacuum tester. This is a pic of the spark plugs I pulled out of #1 and #2. I just about threw up. Suppose I've been a 4 cylinder for a while. Right now the plan is to pull the engine and do a complete rebuild. Has anyone ever bought a rebuild kit from Cdan?
