Oil Sump Paper Gasket Set for Porsche 914-4 (1970-76)
Our Oil Sump Paper Gasket Set for the 1970-76 Porsche 914-4 (1.7L, 1.8L, 2.0L) is built to keep your Type 4 engine sealed tight, preventing leaks that can starve your bearings or foul your garage floor.
This set (OEM ref: 021.198.031.B) includes two high-quality paper gaskets for the sump plates and one copper crush washer for the drain plug, designed for all 914-4 models. The gaskets are precision-cut from cellulose-based material, offering superior crush resistance compared to generic aftermarket options. At 0.5mm thick, they ensure a leak-free seal between the sump plates and crankcase, even under the 914’s high-rpm oil pressure (up to 5 bar). The included crush washer deforms perfectly to seal the 26mm drain plug, preventing seepage during oil changes.
Why us? We’ve serviced enough 914s to know that old sump gaskets often tear during removal or compress unevenly, causing leaks that can drop oil onto the exhaust—a fire risk on a mid-engine car. Our set is engineered for durability, resisting heat up to 250°F and oil degradation. Installation is simple: drain the oil, remove the sump plates (8mm bolts), clean the mating surfaces thoroughly (brake cleaner works well), and install the new gaskets dry—no sealant needed to avoid over-compression. Torque to 7 ft-lbs and swap the crush washer. Takes about 45 minutes with basic tools.
This kit is a small investment for big reliability, keeping your 914-4’s bottom end tight whether you’re autocrossing or cruising. Backed by PMB’s deep expertise and precision, it’s a must for any oil change or engine refresh.
