Ate the top of a lifter

I have solid lifters in my engine.I started getting a lot of valve lash on number 8 intake valve. I took it apart and found that the pushrod wore a hole in the solid lifter cup. The pushrod tip is not worn at all. What caused the pushrod tip to wear through the lifter cup? The faces of the lifters are perfect.The engine has less than 4,000 miles. I will try to post pictures later.

The lifter is faulty, not the first set of Mopar size .904 solid lifters to do that You should take the motor apart and see what other colateral damges there are, cylinder walls, piston skirts, oil pump, camshaft and so on

i had the lifter cup start eating itself on the inside of the lifter body. like you, nothing wrong with the lifter body at all, just the cup that sits in it

one of the reason i moved onto lifters with wheels

Sometimes you can just replace the lifter pushrod seat and keep the lifter on the lobe it came from.

I would like to do that to all of them. Who does that?
