Default TC88 Rattle

2001 FXDXT. Slip on Vance and Hines mufflers, SE hydro cam plate upgrade, S&S lifters and solid pushrods, rocker lockers, Torrington bearings, and all the right gaskets and whatnot all installed over 12k miles ago.

I had my primary hydro chain tensioner fail in my cam chest. Pulled it and replaced it with a new one and a new chain. New gaskets for exhaust and cam chest were installed, and now I have this sound ONLY when warm:



I found no metal and no signs of any other failure in my cam chest.

I know I have good oil pressure, a little slop in my crankshaft sprocket but that can't be the cause.

Any ideas?

Ended up being the retaining ring in my exhaust interconnector. Old gasket was super worn out and didn't hold pressure on the ring so it rattled once it got hot. Replaced the gasket (newer one is way thicker) and did not put retaining ring back in.
