collapsed lifter of wiped cam?

[Hank70SS]

You can take the head to a machine shop but no oil to one lifter is not a problem with the head. Since it's off you could have them check the valve guides and valves if you want.

You're not getting oil to or through one lifter. Set the lifter for the problem valve on a piece of glass or other perfectly flat surface. The lifter face should have a very slight crown to it, that's what makes it spin. You can also lay a new razor/cutter blade across the lifter. It there is no crown to it, it's shot. The crown is very slight but needs to be there. Also look for any hairline cracks in the barrel or burrs anywhere. They don't crack often but Ray (rbarnes) had one last year.

Sometimes just an oil change with filter will help a collapsed lifter. I didn't think of that before, sorry. The new oil and filter will usually raise the oil pressure and may clean out a blocked passage.

Did you run the engine with the valve cover off? All the push rods should be spinning, if not you have a problem lifter or cam.

Good luck.
