Finished Clutch / IMS Job, now have scary mystery squealing noise

[Topless]

Thinking out loud... If a chain tensioner became hyper-extended and was stuck beyond it's normal range of travel due to movement during the IMS retro, would it cause a nasty noise like that? My brother developed a squeal on his 99 and it was worn out chain tensioners.

I've been thinking about what you said earlier, Topless. What sort of noise did your brother experience, exactly?

It was a squeal that was most noticeable when revving up from idle (loading the tensioners). When the chain tensioners were pulled, they were completely worn through.

Eric is right you still have a chain load on the ims. Replace the tensioners and you might just save her.

BB,
There is a lot of helpful information here... However you did see fresh rub marks on the old flywheel and engine case. Are you sure the fly wheel is on correctly and flush with main shaft? Any possibility the flywheel is not lined up with the guide pin? Just a thought...
