How many ,miles on the engine ? I've got over 6000miles and have not run into that problem , yet ? Dd you use hardened shafts and the cryo rockers ? Going to take off the heads and intake again this week and look for any problems
Didn't use cryo's, I bought PN HUG 15063 PREMIUM SB 1.6 ROCKER ARM KIT W/ SHAFTS CNC'D ALUMINUM ROCKERS. INCLUDES SPACERS, SHIMS & GROOVED SHAFTS.
Ive got about 7000 on this last lifter set and probably 4000 since the last crocus cloth cleanup of the shafts on the lathe. 3 sets of retro rollers...they sent me new ones after they got mine back each time no charge except shipping. Ive had the rocker shafts out 4 times to clean them up. There's about 20,000 miles on the motor since rebuild. I run Beehives with 135 lbs seat pressure closed I think it is...and the wipe is centered and narrow. I got the heads from Brian @ IMMengines and had the rockers installed by my builder at the time.
