First one had this knocking sound that we couldn't find, did the whole job of guides and chains, even did vanos transmissions ($500/pop) and the lifters, at the end it still knock, no power loss just knocking, the main suspect was main bearings but at that time (around 2011) it was cheaper to get used engine, so I found this one with around 120k documented mileage, the engine was healthy as it put down 260whp/300lb ft on the dyno but the guides just shattered one day.
