I was taking off stock intake to upgrade to the fast intake. Before I took the intake off followed instructions for compression test. Here are my readings. 1-195, 3-190, 5-190, 7-190. And 2-165, 4-170, 6-180, 8-165. According to the instructions these should be good. The main question I have is as you can see in the pictures there is some oil and they are dirty. However #1 is very clean and that's the only one that's clean. This still has stock pvc system no catch can. Does have filter/breather on cover. Any ideas why only # 1 is so clean? The first pic is 1,3,5 the second pic is 2,4,5
