Thanks. Dino juice makes it worse, in the sense that it takes longer to go away in cold weather. I assume this is a viscosity phenomenon. Last questions. (1) I have been waiting till it goes away to engage a drive gear, assuming this would protect the engine. It takes about a minute. Is this necessary or desirable?
(2) How much might it cost to replace a lifter? It’s a 1998 Chevy 350. (3) I guess one would do that if the noise didn’t go away, right?
