I have a new chain on order for my OM617. As a race engine, it's cheap insurance as I have NO clue about the state/age of the existing chain. Besides, I want to advance the cam a bit for performance reasons - the guys in the Diesel Performance section say it's a power-adder and I need all I can get. So 2* and a 5* key are also coming.

Really, I just wanted to say that this thread is what makes this forum worthwhile! I love that the OP got helpful support without a lot of crap!

Yea, US!!!!
