rocker or lifter noise please help

rcottick said

Well I puuled the intake and all the lifters. The drivers side all lifters were solid passenger side 5 were not pumped up. After looking in the lifter bores the driver side has has large holes and you can see the oil galley but on the passenger side, someone has bushed or filled in with bronze all the holes so no oil can get to the lifter. I am assuming this is not supposed to be this way. And that would explain all the noise and why the lifters werent pumping up. Remeber I switched from a solid cam and lifters to a hydraulic. Now what the heck do I do???????

Holy crap! I just can't believe the things that I've seen on this forum. Sorry to hear of your deliema rcottick.

The only right way to fix this is (and you're not going to like it) is to pull the engine, strip it down and bring it to a real, honest-to-goodness qualified machinist and let him know what you found. Lord knows what else you might find when you break this thing down. At the very least the lifter oil galley plugs will have to come out, a drill run through and the lifter bores de-burred. This is assuming that the nitwit who bushed the bored, bored them straight and true to begin with. If not, the block may be scrap.

Solid rollers back in the day relied on splash oiling and the lifter bores could be bushed without drilling, but they would self-destruct on the street due to the lack of oil to the roller bearings in extended idle conditions. This was also done to route more oil to the crank and rods. Now, some solid roller manufacturers have gone to pressurized roller bearings to survive street/strip duty.

Again, sorry man.

EDIT: I see grumpus has already answered and he is right too.
