My car started making a loud knocking noise and I found out it was the rocker arms and push rods. So then I replaced them and after I did I turned it on and it continued making the knocking sound.
Do you
have the same problem?

Good evening,

I would have a manual test done to be sure you have oil pressure. It sounds like you have no pressure on the rockers.

You can rent the tester at a parts store. Remove the oil pressure switch and insert the tool.to perform the test.

I posted below the location and the needed pressure.
