Lifters losing pressure.

So I ran it and popped the valve covers off and everything was solid as it should be. Checked it 2 hours later, still good. This morning, 6 or 7 hours later, I had 2 soft lifters. Just not pumped up. I now know the problem, I guess I'll live with it at least for now.

They are relatively easy to dis assemble and clean. Sometimes its beneficial as crud gets hung up in em. Might be worth a try before buying another set.
