Its construction is built to OEM specifications, so it suits a daily driver and a heavy-duty work truck alike.\u003c\/p\u003e\n\u003cp\u003eOn 2017-2019 L5P trucks that run a lot of short trips, owners have reported fuel getting into the crankcase oil. The signs are an oil level that creeps above full, foamy oil, or oil that smells like fuel. The common advice for those trucks is a shorter oil and filter interval, in the 5,000-7,500 mile range, instead of stretching it out. If your truck lives on short runs, it pays to keep a spare filter on the shelf.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOne ACDelco PF2232 engine oil filter (SKU GM19385578)\u003c\/li\u003e\n\u003cli\u003eDesigned to meet or exceed OEM specifications for 6.6L Duramax diesel engines\u003c\/li\u003e\n\u003cli\u003eSuited to a routine oil change or a full service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout ACDelco\u003c\/h2\u003e\n\u003cp\u003eACDelco is General Motors' own parts brand, with roots going back to 1908.

On the LB7, the early water pump seal design was a documented failure, as early as 75,000 miles. On the LMM, water pumps seep at the weep hole and leave crusty residue as they age and heat-cycle. On the L5P, the plastic upper radiator hose fittings and the edges of the coolant reservoir can crack after long heat exposure, which leaves orange DEX-COOL residue and a sweet smell. If the system is hard and pressurized after shutdown, or the overflow tank bubbles, look at the head gasket instead.
