This is the valve cover gasket produced for the iconic E30 (1987-1991) 3.16i and 3.18i models of the BMW 3 Series, featuring the 4-cylinder (8 Valve and Timing Belt) M40 engine, from the world's number one German sealing equipment manufacturer ELRING (703.532). It offers a precise solution according to OEM standards, replacing your old gasket that has hardened and turned to plastic due to the high heat of these classic engines, causing oil leaks onto the block. It completely eliminates the burnt oil smell coming from under the hood, the smoke on the exhaust manifold, and those ugly oil sweats, keeping your E30's engine bay spotless.
- OEM German Quality ("Das Original"): ELRING is the original gasket manufacturer used on the BMW factory assembly line. It provides 100% compatibility with the thermal expansions of your engine and the wear caused by years.
- Special Elastomer Structure: Manufactured from a special rubber profile that shows maximum resistance to high temperatures and the abrasive chemicals in synthetic/semi-synthetic motor oils; it does not harden prematurely.
- Prevents Fire Risk: Oil leaking from the valve cover drips onto the hot exhaust manifold just below, creating a serious smoke and fire risk in E30s. The new gasket cuts off this dangerous leak like a knife.
- Perfect Mold Fit: Fits millimetrically into the grooves of the M40 engine's valve cover; no need for stretching, pulling, or supporting with liquid gasket (silicone).

Frequently Asked Questions (FAQ)
My car is a 1986 model E30 3.16 (Carbureted), will this gasket fit my vehicle? **IT WILL NOT FIT.** The older E30s produced before 1987 used the M10 engine with a timing chain. This product is for M40 engines used after 1987 (in models with plastic bumpers). The shapes of the valve cover for M10 and M40 engines are completely different. Please ensure your engine is M40 before ordering.
Is it necessary to use liquid gasket (silicone) when installing the valve cover gasket? No, this is a very common mistake made in E30 restorations. ELRING gaskets provide sealing without the need for additional adhesives. Using liquid gasket can cause the gasket to slip out of its groove and block oil channels. Only a lentil-sized amount can be applied at the two corners where the camshaft seal meets; the rest should be installed completely dry.
Will it fit my E30 318is (M42) model? **NO.** The E30 3.18is models feature the legendary 16 Valve M42 engine. The valve cover for the M42 engine is much wider, with the spark plugs in the center and a dual camshaft design. This product is only for the 8 Valve, single camshaft M40 engines.
