sup guys im going crazy just bought a virgin db2 and im going nuts with a valve train rattle. Now heres the intresting part it doesnt rattle on idle, only under accelaration. please any ideas??? ive already tried adjusting the valve clearence .007 intake and .008 exshaust.
LMA’s (Lost Motion Assemblies)? I dunno, it always difficult to diagnose these issues via the internet… but doing a compression test wouldn’t hurt.
Well i did run a compression test and their all about 126-130. So ive got good compression. Now im suspecting that maybe one of the followers(rocker arm) is flat. I dunno this has been a brain buster. Im thinking of just removing the cams and checking all the followers.
It was the lifter/tappet/lma. Thanks for the idea.
