Rally Road Oil Fill Cap, BMW E36

No more drilling valve covers and installing crankcase vent fittings; Rally Road designed this Oil Fill Cap with a AN10 port in the top to allow their low profile AN10 swivel fitting to be installed so you can leave your catch can hose attached to the cap while easily removing it to add oil.

The Rally Road Oil Fill Cap was 5-axis CNC machined from 6061-T6 Aluminum and the machined retainer bar and expanding assembly ring are made from 316 Stainless Steel.  The same goes for the AN10 swivel fitting: it's made from 6061 Aluminum and the body is 316 Stainless Steel.  All O-Rings are Viton for extremely long life.

This cap fits both Plastic and Magnesium (sometimes thought to be Aluminum) Valve Covers. 

Included is (1) Oil Fill Cap and (1) AN10 Swivel Fitting as pictured.

Install Tip: Use a little oil to lubricate the rubber seat on the underside of the cap and press down when turning.  This will help it rotate into locking position.
