If only one cam lobe did this I would say check for plugged oil spray hole over that cam lobe. Dan

Does that rocker move smoothly? Perhaps that LMA started putting a lot of pressure on that rocker somehow?

45,000 mi since installed. How many miles did the rockers have before that? 8500 RPM's you have used up your warranty on "race" parts.

parts list,

crower probillet rods, with 11.0 slugs, prodrive oilpump, on the bottom, bearings spun on the mains rods and pistons fine., portflow head, ferrea valves polydyne coated, crower eibach valvetrain, crower stage 3's, arp all around, single runner im, 68mm billet tb, aem CAI, unorthodox pulleys, no ps, or ac, clutchmasters 8pound, act extreme, lsd tranny. sad to see the mains took a dump.

yep 45k later... oh well... lost count after how many drag pass's it made after the first year head was a 2000 prelude head, with 5 miles on it, before the install. lma's were also new. rockers were all clearanced for the intalled height, and skunk2 2 gears were indexed. when the bearings went, one piston hit two exaust valves.. tight specs. i think so

this was assemble by me in 2002.... hahaha so it's been a while.
