Interesting. So the sound would be emanating from the lifters down below, or the valves up top? Devil's advocate question: why wouldn't I hear that more loudly directly at the source? Why is it loudest at the bellhousing?If sound is increasing when you're on the Bellhousing, it seems like sound is traveling through the block. BGarcia beat me to it, but I too would check the valve train, particularly the lifter/pushrods before tearing anything apart.
FWIW, if/when you get to that point of replacing the Pilot bearing, JimC sells a super-duper one I've been itching to try:
Pilot bearing, 1F/2F/3F series enginesThere's nothing worse than having to drop the transmission & transfer case and pull off the clutch to change a dried out pilot bearing. That's a lot of backbreaking labor that could have been saved by installing this top quality made in EU by SKF aerospace bearing filled with synthetic grease...tlcperformance.com
