Then you have a tensioner issue, or chain issue, or both. The IMS tensioner is the worst for this, and as it rattles it hammers on the IMS bearing, and it's tensioner paddle and wear pad. I think this contributes at least some to IMSB failure.

Its not a normal occurrence; just because most do it, doesn't make it mechanically acceptable. The tensioners for 5 chain engines have been revised 7 times, 3 chain have been revised 3 times.

If its rattling at start up, things are wearing. Period.

A huge amount of preventative packages we are doing these days end up getting chains, as most are stretched and send the tensioners out of range.
