PPE built this 304 stainless steel oil return pipe as a direct OEM replacement covering LLY, LBZ, and LMM Duramax engines in one part. Stainless construction stands up to the underhood heat and road exposure that wears out the factory pipe, keeping oil returning from the turbo the way it should.
Precise fitment comes from the corrugated bellow section, which flexes with engine movement and thermal expansion rather than loading up the connections. The pipe bolts on at the factory mounting locations with no cutting or modification, making it a straightforward fix for 2004.5-2010 Silverado and Sierra owners.
