lack of oil?
afew months back i had replaced my springs and rockers. i installed 918's beehives and comps 1.6 magnum rockers. the set up was great and i thought working perfectly fine. today im tearing down my engine for my cam swap (that ill be posting when i get more work done) and i found that almost all of my rockers show excessive wear on the pivot ball and the bottom of the rocker is blued from heat. im asking if it would be ok to possibly clean them up and reuse them and what would cause this to happen. lack of oil ? here are some pics
and this is the reason for doing a cam in the first place. do you think i can reuse this lifter ???

wow yeah I would go ahead and reuse the lifters and then I would sandblast those rockers and run them through the dishwasher no less than 3 consecutive cycles and they should be good to go. Did you use assmebly lube when you installed them, and did you use new pushrods?? Sometimes the oil passages in the pushrods are gummed up with the sticky oil they use for corrosion prevention from the factory. When I installed my rockers and pushrods I had a hard time getting oil up top initially so I removed the valve covers added a capful of oil into each rocker and ran it up to about 3,000 rpm and finally oil started pumping up top. If yours went through the same scenario it might have happened off of initial start up. I am not sure but if we are shooting in the dark that is a probloem that I ran into, hope it helps

Do all the rockers look like that or is it only the one with the messed up lifter?
I don't know if I'd reuse the rockers with aftermarket spring pressures and until you address the oiling problem it will just happen to new rockers too.

yup. there are only 2 or 3 that dont show that much wear. im going to probably be pulling the engine and doing a gm white spring in my oil pump at the very least (i already have it) idk if i want to rerun these rockers or not. i dont have that much on me especially if im going to freshen up the bottom end (which im very much considering)

its common with those rockers. i would get the ball with out the grooves in it to replace the other ones. the groove causes the oil to drain out too fast not taking the heat with it. i had the same prob on my old tpi car.

I know you may have a budget, but I would try and buy new rockers. If they blued from heat as well as got worn, I just wouldn't chance it unless you plan on going into the top end pretty frequently to check up on things anyway. I mean we're talking about a couple hundred bucks versus the damage a broken rocker or metal contamination could cause over the long term. Just my 2 cents though...and believe me I understand budgets, I just would hate to see something relatively inexpensive do a lot more in damage.
*maybe keep them as spares should something happen down the road...
