BMW 3 Series E36 (1992-1998)

If your M50, M52, or M54 engine takes a few seconds to build oil pressure after sitting, there's a good chance that your factory oil filter housing drain back valve has failed. Over time, the factory plastic check valve degrades, allowing oil to drain completely out of the housing and back into the oil pan while sitting. Every cold start essentially becomes a dry start, resulting in a loud ticking noise and causing unnecessary wear on your engine's internals.

Unfortunately, BMW does not offer this check valve as a standalone part, forcing you to purchase a costly, complete oil filter housing assembly just to fix one failed plastic component. Thankfully, our team of BMW enthusiasts took note of this common failure mode and designed a permanent, cost-effective fix.

Our Billet Oil Filter Housing Drain-Back Valve is designed as a direct-fit upgrade for your factory oil filter housing. CNC-machined from high-strength billet aluminum, this upgraded valve restores positive sealing to keep the oil filter housing fully primed. Maintaining this hydraulic prime ensures rapid oil pressure stabilization upon startup, directly mitigating dry-start bearing wear and top-end lifter starvation without requiring the purchase of a complete OEM housing assembly.

The 6-speed Getrag 420G transmission, found in the European E36 M3 Evolution and E46 M3, has become an increasingly popular swap amongst E36 owners. Its increased strength, longevity, and overdrive sixth gear make it a great choice for both track cars and daily drivers. Unfortunately, many of the components needed to complete this transplant have become hard to source. Despite increased demand from enthusiasts, BMW has blocked the sale of European E36 M3 parts into North America.

With this in mind, our team of engineers went to work designing a direct replacement and upgrade for the unavailable, 420G-specific shifter arm. Precision-machined from 6061-T6 billet aluminum and clear anodized, our replacement carrier is durable, lightweight, and built to last. It is dimensionally identical to the OEM carrier, ensuring compatibility with the OEM shift carrier bushing, shift lever, and our Double-Adjustable Short Throw Shifter Kit (T#557266).

Features & Benefits:

6061-T6 billet aluminum construction provides excellent durability and longevity Mil-spec clear anodized for superior corrosion resistance Dimensionally identical to its OEM counterpart, ensuring compatibility with all factory shifter components Confirmed compatibility with the Turner Motorsport Double-Adjustable Short-Throw Shifter Kit (T#557266) Product Development:

Our E36 420G Shifter Arm was designed, engineered, tested, and quality inspected by our Research and Development team. We strive for nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Lowering your BMW does wonders for appearance and handling, but it also changes suspension geometry in ways that can hurt performance. As ride height changes, angles between the sway bar, control arms, and axles shift, which can cause binding, poor fitment, and added stress on the factory fixed-length end links. This is especially noticeable on cars equipped with coilover suspension, where slight height differences side to side can preload the sway bar and lead to inconsistent handling.

Our team of dedicated BMW enthusiasts set out to remedy this common issue with a set of Adjustable Rear Sway Bar End Links. Designed with performance in mind, they offer a fully adjustable range from 100mm to 120mm, helping eliminate preload, restore proper suspension alignment, and improve overall sway bar function. Constructed from high-quality billet aluminum, these end links are built to outlast the factory cast components and are finished with a black anodized coating for excellent corrosion resistance. Laser-etched wrench size markings allow for quick, easy adjustments while installed on the vehicle. Unlike the factory design, these end links use spherical rod ends at the control arm for increased responsiveness and a more direct handling feel. A unique knurled bushing design also ensures compatibility with the OEM sway bar, offering a first-to-market solution for enthusiasts looking to retain factory components.

Features & Benefits:

Adjustable from 100mm to 120mm Strong 6061-T6 billet aluminum construction Black anodized finish resists corrosion Spherical rod ends improve response and handling feel Polyurethane bushing with knurled bore helps retain grease Fits factory rear sway bars on E23, E24, E28, E30, and E36 Laser-etched markings for quick and easy adjustments

Over time, the factory valve cover hardware on M50, M50TU, M52, M52TU, M54, S50 (US), and S52 engines is subjected to continuous heat cycling, oil vapor, and moisture, causing original cap nuts to oxidize, corrode, or thread-strip during routine maintenance. Our Polished Valve Cover Cap Nut serves as a direct replacement designed to address these common failure points while improving upon overall engine bay aesthetics.

Because maintaining precise gasket compression is critical to preventing oil leaks, these cap nuts and washers are machined directly to OE-style dimensions. This exact fitment allows for direct compatibility with original and replacement valve cover studs (see T#55317643) and ensures the hardware can be torqued precisely to OEM specifications without guesswork. Manufactured to grade 8.8 structural strength standards, the hardware maintains the necessary clamp force required under normal and high-performance engine operating conditions.

To resist corrosion, both the cap nut and washer undergo an electroless nickel plating process during production. Unlike standard zinc coatings that dull or rust over time, electroless nickel provides a uniform layer of corrosion resistance that withstands long-term chemical exposure and extreme temperature swings while giving the hardware a polished, high-end appearance. Each cap nut assembly includes an OE rubber washer seal, ensuring a tight, leak-free barrier that prevents oil from escaping through the mounting studs.

On M52/S52-equipped BMWs, the factory crankcase ventilation (CCV) system is a notorious weak link. Between brittle plastic corrugated hoses that crumble from heat soak and an internal cyclone diaphragm prone to tearing, a failing CCV leads to massive oil consumption, vacuum leaks, and that dreaded "howling" whistle.

This kit addresses these issues with all new components and hardware. Both oil separator hoses, the cyclone separator itself, the mounting grommet, and the retaining bolts are included. Servicing this system is guaranteed to restore performance lost as a result of worn CCV components.

Kit includes:

Cyclone Separator/Crankcase Pressure Regulator Valve High Performance Silicone Breather Hose Return Hose Mounting Grommet Hex Bolt (3)

A throw adjustment can be done in the car without removing the shifter DSSR (109MM) - E36 420G

Like all OEM selector rods, the factory part uses single-shear attachment, allowing for deflection within the shifter linkage. The result? Vague, imprecise gear selections that detract from your overall driving experience. The dual-shear selector rod (DSSR) design spreads the torsional force of gear selections across the selector rod joint, reducing deflection for increased precision. Our DSSR is precision-machined from durable 304 stainless steel to further reduce deflection and resist corrosion.

Features:

Provides a more positive feel in the shifter by reducing play in the linkage due to minimized deflection Manufactured from 304 stainless steel for superior corrosion resistance and durability Replacement for 25112228055 (European E36 M3 Evolution) HEAVY-DUTY SHIFTER ARM - E36 420G

To cater to the six-speed swap E36 community, we designed a direct replacement and upgrade for the unavailable, 420G-specific shifter arm. Precision-machined from 6061-T6 billet aluminum and clear anodized, this replacement carrier is durable, lightweight, and built to last. It is dimensionally identical to the OEM carrier, ensuring compatibility with the OEM shift carrier bushing, shift lever, and Turner Motorsport Double-Adjustable Short Throw Shifter Kit.

Features:

6061-T6 billet aluminum construction provides excellent durability and longevity Mil-spec clear anodized for superior corrosion resistance Dimensionally identical to its OEM counterpart, ensuring compatibility with all factory shifter components POLYURETHANE SHIFTER ARM BUSHING

This shifter bushing is designed to remove the shifter play caused by an old, failed rubber shifter bushing. Manufacturing the bushing from polyurethane instead of rubber reduces the amount of stretch caused by the moving part through the bushing. This maintains the direct crisp feel from your shifter assembly. When your OE shifter arm bushing begins to fail, you will notice slop in shifting, potentially making it easier to miss gears, and it often causes an obvious vibration and movement from the engine RPMs.

Features:

Corrosion-resistant 304 stainless steel mounting sleeve with bonded 70a polyurethane Stiffer bushing results in a crisper shifter feel and a more engaging driving experience.
