OK, a little background. I am installing a hydraulic roller cam, got the cam in, installed the timing chain and cam button bearing. Next need to make a nylon plug to put in the center recess of the cam button bearing.

Well tonight I finally get a chance to do some measuring and I find out the stock GM cover is not deep enough! The bearing is taller than the depth of the cover. This is driving me nuts, it's one snag after another. I think I'll just machine a button from Nylon and give up on the fancy roller (that won't fit).

I don't know why I didn't do this to begin with. Thoughts?

I don't have clearance behind the water pump for a deeper cover. Cloyes makes one, been there done that. I will just make a lower profile button. I'm just bitching about the snags I keep running into trying to do something very simple. It's driving me nuts, that engine was supposed to be together last month.

Sounds like it will work, but be sure to have between.003-.008 clearance between the button & cover, because the cover metal will expand.
P.S. HI GUYS!!! :cheers: :cheers:

Looks like the .800 one would work but these were my choices when I bought my cam from Summit:

Of the 10 listed there all are .925-.950 (exept one .640 button). The Lunati that was sold to me is .950 and my cam is a Lunati. Well it's done now, I machined the button at work today.

I thought you just grind them down to the size you want :thumbsup:
