Problem
The oil filter bypass valve may be forced open during cold start-up on certain 3606, 3608, 3612, and 3616 Engines due to the viscosity of the oil. New oil filter housings, which do not contain a bypass valve, need to be installed to prevent contaminated oil from reaching the clean side of the oil filter and the lubrication system. Former 7W2469 Housings - Oil Filter need to be removed from dealer parts stock.
