This BMW 335i came in with a leaking oil pan and a no start condition, the engine seized due to catastrophic rod bearing failure. A used motor was sourced and partially refurbished to replace the failed unit. Valve cover, oil pan, oil filter housing and high-pressure fuel pump were all re-sealed, and the intake valves were walnut blasted while the engine was out of the vehicle. Then new turbocharger gaskets and fresh fluids had this engine back in top running condition.
