Valvetrain rattling, major misfire.....
Trending Topics
I'm assuming they bled the lifters (which I'm sure they did...it's AMS after all) but was there enough time given to allow the lifters to fill back up with oil? Friend of mine had an issue after he had his cams installed where some rockers popped off because the lifters didn't pressurize back up, could be the same issue on yours.
