Is your 6.7L Powerstroke developing an oil leak around the upper oil pan or lower engine block? The MAHLE OS32478 Upper Oil Pan Gasket Set is designed to restore a proper seal in one of the most critical areas of your engine. Over time, factory gaskets can shrink, crack, or fail due to constant heat cycles and vibration, allowing oil to seep from the upper oil pan and cause messy leaks. This gasket set helps eliminate those leaks, maintain proper oil containment, and keep your engine bay clean. Whether you're tackling a repair during routine maintenance or performing a deeper engine service, this gasket set keeps your Powerstroke sealed and protected so you can get back on the road with confidence.

The MAHLE OS32478 is engineered with OE-style molded-rubber gasket construction to withstand the extreme temperatures and pressures found in modern diesel engines. Its precision-molded design ensures a proper fit between the upper oil pan and engine block while maintaining consistent sealing pressure across the mating surfaces. Built to meet or exceed OEM standards, this gasket set provides long-lasting durability and reliable leak prevention. MAHLE’s world-class sealing technology and manufacturing quality make it a trusted choice for technicians and diesel enthusiasts alike.
