I need some help please, Just bought myself another VR6 Bought it with knocking noise!! Real good deal as body is immaculate. any hows, my first guess it was one of the big end busted off, so i remove the sump and checked underneath, All was good nothing broken and no bits in the pan. (the knocking was really loud and it sounded that engine was not running on all six that's why a assumed it was one of the big ends or conrods that snapped) So after that i removed rocker cover to check cams. Nothing broken but the timing chain was really loose, I could lift it and mover over about the teeth on t
