I bought a good running to30 from my wifes best friends FIL. He had a drop in oil pressure and put anew gauge on to confirm. I never got to talk too much to him so....
I put a oil pump in and sealed the oil pickup arm and now i have 20 psi cold fast idle. Checked one main w plastigage n was w/i specs. Like a good mechanic I'm going to check the valve lash quick b4 i set this out for sale and one rocker is worn so bad its cocked on the rail but... has been adjusted. So someone knew about the problem and ignored it. Now i can't sell it and keep a straight face.
I ran it the other day with the plug out of the far end of the rocker tube... nothing. Ran it for 5 min and then pulled the plugs and rocker assembly off quick and spun it w the starter n have 4-5 psi but no oil up top.
Could a cam bearing(s) be so bad to not allow 20 psi of oil to get up top? Does the oil have to flow thru the last cam bearing on its way up so a spun bearing would block the path?
What would you do first?
The valve cover and original rocker assembly was dry, like sitting out in the driveway dry. But... that was with no oil pressure due to a worn pump.
