Oil Pump To Case Gasket, Fits Full Flow Filter Pumps, Inner

Premium EMPI Inner Oil Pump to Case Gasket for Full Flow Systems

When it comes to maintaining the heartbeat of your air-cooled engine, the oiling system is the one area where you simply cannot afford to cut corners. This EMPI Inner Oil Pump to Case Gasket is specifically engineered for high-performance engines utilizing full-flow filter pumps. Unlike standard gaskets that might not align perfectly with the unique porting of a full-flow setup, this gasket ensures a precision seal between the pump body and the engine case. Maintaining a vacuum-tight seal at this critical junction is essential for ensuring that your oil pump can efficiently draw oil from the sump and distribute it through your external filtration and cooling lines. A failure here doesn''t just mean a messy leak; it can lead to oil aeration or a drop in oil pressure that risks the longevity of your bearings and crankshaft.

Crafted from high-density, oil-resistant gasket material, this component is designed to withstand the thermal expansion and contraction cycles inherent in the Volkswagen magnesium or aluminum engine case. Whether you are building a high-revving street Beetle, a rugged off-road sand rail, or a dependable daily-driver Karmann Ghia, using the correct "Inner" gasket is paramount. This gasket is designed for pumps with 8mm mounting holes, providing the exact clearance needed for a snug fit without bunching or tearing during installation. At Appletree Automotive, we understand that even the smallest part plays a massive role in your VW''s performance, which is why we provide only the most reliable EMPI components for your air-cooled assembly.

Pro Tips from the Appletree Specialist Team

Tip 1: Surface Preparation is Critical

Before installing your new EMPI gasket, ensure that both the engine case mating surface and the back of the oil pump are perfectly clean and flat. Use a plastic scraper or a lint-free cloth with a bit of solvent to remove any traces of old gasket material or oil film. Avoid using metal scrapers or screwdrivers, as magnesium engine cases are soft and easily gouged. Even a small scratch can create a leak path that the gasket may not be able to bridge, leading to a loss of oil pressure or annoying external leaks.

Tip 2: To Seal or Not to Seal?

In the air-cooled world, there is often a debate about using supplemental sealants. For this inner oil pump gasket, it is generally recommended to install it "dry" or with a extremely thin smear of a high-quality non-hardening sealant like Curil T. Never use RTV silicone in this area. Excess silicone can squeeze out into the oil galleries, potentially breaking off and clogging your oil passages or the oil pressure relief valve, which can cause catastrophic engine damage. If your surfaces are flat and clean, the gasket material itself is designed to swell slightly and seal upon contact with oil.

Tip 3: Proper Torque Sequence

When installing the oil pump over the gasket, always tighten the four 8mm nuts in a cross-pattern (diagonal) sequence. This ensures that the pump body seats evenly against the case, compressing the gasket uniformly. If you tighten one side completely before the others, you risk "cocking" the pump, which can lead to a vacuum leak at the gasket or, worse, binding the oil pump gears against the camshaft drive slot. Always check that the engine rotates freely by hand after the pump is torqued to ensure nothing is binding internally.
