no it is the ball seat just wrong from that i have seen you need a 210 push rod end or need to be check for bind and like every roller rocker they need to be check it mid lift for the right push rod length the oil is getting thru the push rod the the ball cup would still get oil that has nothing to do with it. the rocker finish?well that could be they are not quality but are hard enough to eat the push rod ball off for the poly lock rubbing alot roller rockers in time will do this the body walks a bit and the bearing in the body start to wear or just loose from the get go

not sayin ur wrong on this, but there was only about 2 - 3000 miles on these rockers. and with this being just a little street 283, it was a far cry from being up to any performance level!!

just thought i'd show this with everyone to let people know!!

well you can think any thing you want i build engines for a living i know better roller rocker on the street start to fall apart at 3000 miles. less they are good ones that very small amount of alum from hitting the polylock will not hurt nothing . the push rod tips that a deferent story you should check pushrods for size and check rockers at mild lift that is just the right way to do it .if not you will just wear out your valve guilds anytime you do not use a stock rocker arm the stock stuff is better for long use if your not wanting to check stuff .there is no short cuts
