I'm sure you have all heard this already and I've tried to search the forum for it. I've been trying to set my valves for a couple of weeks now. I've tried the crane cam way and the comp cams way which are the same. They state to pick a cylinder and when the exhaust opens adjust the intake-and when the intake opens fully and almost closes adjust the exhaust. I've done this several times....I've got to zero lash and tried adjusting 1/4,1/2,3/4, and 1 full turn each time. I get good results w/ performance and all but the valvetrain is just noisy as hell! and I can't stand it.
I also tried adjusting w/ the engine running w/ limited success. I can get all the rockers quiet but the performance doesn't seem as good. By this I mean the car doesn't accelerate as fast and seems to surge. When I did the adjustment I would pick a rocker and loosen it until it rattled and then tightened it until it became quiet....but that's as far as I could go on all of them. I could get them where I could actually feel them get to the point where they were snug but I could not get them the additional 1/4 turn that is required after you get the rocker quiet. If I turned any farther the engine would run like shit or die. I did have my vacuum gauge on the car while I was doing the adjustment. I noticed that when I tightened the rockers my vacuum would decrease and when I loosened them the vacuum would increase. Doese this play a role in the actual adjustment? Should you try to get the highest manifold vac. while adjusting? My rockers still make noise even after getting them all quiet and then taking the car for a drive. Do I just have to put up w/ the noise?
I also noticed that oil is not squirting out of the pushrods/rockers. I mean it comes out but it doesn't come out squirting like I was told it would....meaning squirting all over the place. If I rev up the engine it will squirt out better but not like I thought it would. On some rockers it will squirt out good on others it will just come out the rocker hole and fill up the where the polylock is. Am I doing this procedure right or do I have crappy lifters?
