\015\012if could also be the vanos, variable valve timing. but at 2500 i'd say crank, especially if it has that rattle tone. that sound is a wearing connecting rod bearing. when it goes, the engine basically blows up and the insides try to escape through the engine wall...that destroys the bottom end, when that happens, stuff sometimes also goes up into the head, that destroys the top end.

\015\012then you would need a long block.
