hi all
have driven the car today, and when i come home, there was a medium loud ticking noise under the drivers side valve cover... removed the V/C and started to look for things..nothing noticeable i started the car with V/C open, the following occured: on the firewall side, there was plenty of oil coming from the pushrods.. the amount of oil decreased going towards the front of the engine, and on the 2 pushrods, nearest the front, cyl #1 no oil was coming from them.... also, the very first lifter on cyl 1 was compressible, so no oil in it... what the hell is going in here? the engine is based on a GMPP block, once i swapped the cam, but not the bearings..possible failure? the oil pressure is just 30psi hot, this with an Melling Performance +25% pump... any opinions? thank you |

Is there something in the pushrod?
How does this lifter look? |

Sounds like maybe you have a bad lifter or 2.

hi
ok, 2 bad lifters...but, why are they on the same cyl#1? also, there are coming gobs of oil on the lifters near the firewall, and then, each lifter that comes nearer to the front gets less oil....like the pressure in the oil rail is dropping from back to front... i have no clue, what this could be thank you |
