Found three rockers with so much lash that I am surprised I didn't loose the push rods or lash caps. I stopped with the feeler gauges when I was around .085" so they were real loose. I knew something was wrong when I pulled the intake and found three ports dark when the other five were clean. All three were intake rockers on those "dark" cylinders. I was well past the point where I should have run the valves, but this was a surprise since there was nothing to indicate anything was wrong. No noise, misfire, popping....nothing. I will be replacing the lifters anyway, but what else could have suffered? Can't believe this just went a mid 5.8 in this condition.

Check that the ball end on the pushrod and the lifter/rocker adjuster to make sure the radius matches and also check that the adjuster hasn't pushed the threads in the rocker.

Will take a good look at those items tomorrow.

Check every single thing....leave no stone unturned.


You are going to pick up quite nicely when you square it all away.

Brian I forget what rockers you are running but some
of the adjusters are junk and will pull the threads
out and were soft so the push rods beat the cups...
also as said check the dia of the cup to the PR ball...
3/8 balls DONT FIT on any of the cups

Can't believe it ran as well as it did. As mentioned before, you're going to
Pick up substantial gains.

I agree,,if it picks up at all it will be negligable.

When he gets a representative camshaft in that thing, along with a couple other "things", it will pick up accordingly.

Sounds like it is time to junk it and get something with more power

Seriously as has been said already check everything over very well. Leave no stone unturned..
