Some of you guys may have read my frustrations re the noisy Tremec box in my TE50. Well it was all made worse by the fact that the vehicle had dropped a valve. I was told they replaced valve, valve retainer and roller rocker. An assembly error. Vehicle much better now. Only had 3800 kms on the clock. I was told this was the first mechanical failure of the AU3 TE50. I do love it still, but I am a bit nervous that the mechanic assembling my stroker was having a bad day.

The guy that assembled your stroker didn't assemble the heads.

Ah he may not have assembled the heads BUT what could have caused it ?? Could be the assembly of r/ rockers etc ??Especailly that they replaced the rocker!! I'd check to see if there is any marks on the rocker arm where it may have made contact with valve retainer... Poping out the keepers-valve ???

The rockers bolt on to the mount and as they are on a shaft there is no alignment to be done. I would say you have actually had a component fail (be it valve, retainer, or collet) and as the vavle has dropped the spring has shot up with the retainer and damaged the rocker. They are only aluminium and would be damaged easily.
