I bought a used 250 motor. It does not smoke at all.
It has tapping so I took the valve cover off. No oil coming up the pushrods. It is cold here but I am guessing that 5 minutes of idle is enough time to allow oil to rockers.
My buddy suggests replacing the lifters as the oil holes are probably gunked up.
Only costs about $60 bucks but still, I believe I should be able to run a small wire though each lifter to clean the oil passages. Will new lifters add any "PEP" to the motor as he says?
Besides oil pump, screen, lifters, and clearing the pushrods, is there anything else to check. There is alot of "crud" in rocker area. This will be yet another question I am going to post. Thanks for reading and any advise. | | |

30 psi at an idle is pretty darn good. Why can't you save your $$$ by soaking the lifers in Chemtool or something to clean them out. Fill them up the same way with oil and reinstall in the same holes.

You can pre-load the lifters with oil by placing in oil bath and "stroking" them although some cam manufactures don't recommend that.
