ls1 cam swap
my friends impala has a collapsed lifter. we're trying to cover all the bases of what needs to be replaced before diving into it. I already have an LS1 cam from my other car.
What all is needed to swap this cam in? timing gear? valley cover? or can we keep all the DOD stuff and just replace the cam and lifter that failed.

Money just isn't there for a full cam swap with all new parts. Ideally the can is fine and we just need a lifter and new head bolts. But I'd like to plan for the worst just in case.
If it were my car I'd do it, but not much room in his budget for it. The car just got a new trans put in a week ago.
Edit: any chance that a lifter can pump back up on its own? Just got a call that he started the car and no more noise.

Not sure how bad the lifter noise is, but the LS4s all get some - mine is mint but if I don't drive it for a week I'll get lifter tap until it runs a few. Also notice it happens more closer to oil change time, so I change it frequently with Full Synthetic Mobile One.

This is why I recommended a system cleaning first. Things do get dirty and stick. For example if a valve was stuck partially it would leave the play in the rocker or if a lifter was stuck in the collapsed position it also would leave undesirable play in the valve train. So for the few bucks it takes to clean everything first it may save you a bundle in money and time. Even if there is something more serious a pre-clean will only make the teardown easier.
