Just my opinion but having seen three 996s with ims failures and $10k bills, plus one c2 with intermix which required a full engine rebuild... It's a big deal and shouldn't be ignored. At least everyone should know about it because if you get a 10k bill on a 10k boxster you wouldn't be a happy camper
Beyond a clutch (which labor/parts are still expensive) you have to remove the flywheel, release the chain tensioner. Oil has to be drained.
Camshafts must be locked which means removing anothe cover.
Put to tdc, unscrew and pull bearing with a special puller. Tools and parts are $700 not including the clutch or flywheel.
It's about 2 hours of extra work. Nobody would change it for free on top of a clutch unless they've never done it before or realized how much work it was.
