Most of the pulleys on your BMW engine are plastic, which become brittle and frail over time and from engine bay heat. A failed pulley could leave you stranded which is why it is vital to inspect the pulleys during routine maintenance. This is an aluminum version of the stock water pump pulley used on the M50/M52/M52TU/M54 engine in the E36, E46, Z3, Z4, and other models. It uses the same hardware and the original belt as the stock plastic pulley. But the aluminum will last much longer.

If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On older BMWs, the engine ground strap is a thin, non-insulated cable that spans from the engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your BMW! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

FEATURES

Direct-fit replacement and upgrade for E30 (318i/is), E36, E39, E46, and others Solves intermittent grounding issues caused by aging OEM straps Clean, stealthy design that fits seamlessly in factory engine bays Factory length and lug orientation for drop-in fitment 2 AWG tinned copper cable for excellent conductivity and corrosion resistance Zinc-coated lugs, crimped and soldered to resist moisture and oxidation Black UL1015-grade insulation withstands oil, heat, and abrasion Discreet ECS label for a clean, OEM+ look Replaces OEM part numbers 12421737755 and 12421714262.

With exposure to heat and elements, your motor mounts will break down with increasing age. A secure mount is vital to reduce drivetrain vibration and transfer as much horsepower to the wheels as possible. These mounts are an upgrade for non-M E36/E46 owners seeking a stiffer mount without sacrificing comfort and ride quality.

Most of the pulleys on your BMW engine are plastic, which become brittle and frail over time and from engine bay heat. A failed pulley could leave you stranded which is why it is vital to inspect the pulleys during routine maintenance. This is an aluminum version of the stock water pump pulley used on the S54 engine in the E46 M3, MZ3, and Z4M. It's the same size and uses the same hardware and the original belt as the stock plastic pulley. But the aluminum will last much longer.

BMW uses a lot of plastic in their engine components to save weight and money. Unfortunately, plastic is damaged easily and the factory oil filter cap needs a special tool to remove. This aluminum cap is much more sturdy and features a standard 19mm hex post on the top. 19mm is also the size of your engine oil drain plug, reducing the number of tools that you need to complete an oil change. This cap is designed to use the original o-ring seal so no special parts are required. You only have to remove the original 'filter cage' from the original cap and transfer it to the new aluminum cap. The satin black anodize blends in with the rest of your engine bay making this a smart and subtle upgrade.

Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each motor, Cometic offers a number of options to suit your specific motor and needs. *MLS* The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, it’s ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The Viton coating is heat resistant to 2500C or 4820F. The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks. The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design, the MLS gasket promotes an even torque load across the sealing surface allowing for measurably reduced bore distortion. *CFM-20* A perforated steel core with an elastomer surface is ideal for head gaskets allowing heat to be drawn evenly across the gasket surface while providing maximum sealing characteristics when exposed to coolants and oils.

Bavarian Autosport served the needs of BMW and MINI enthusiasts from 1974-2019. In 2019, ECS Tuning acquired the Bavarian Autosport brand, committing to continuing the tradition of excellence Bav Auto is known for. Over the years, Bav developed their own brand of parts, accessories and upgrades. A lot of these parts are engineered and built by OEMs (Original Equipment Manufacturers – companies who make original parts for BMW, MINI, and other European marques). Just as MINI, we work with a variety of manufacturers in Europe, Asia and North America. In many cases, we have sourced parts that are superior to Original Equipment.

A lot of time and resources have been put into developing and evaluating these products, as well as the companies who produce them. We stand behind every product we sell. If any product fails to meet our standards — or our customers' expectations — we won't sell it, and we're certainly not going to put the Bavarian Autosport name on it. In fact, we're so confident in the quality of these parts that we back every Bavarian Autosport brand part with a 2-year warranty.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On E70/E71 BMWs, the engine ground strap is a thin, non-insulated cable that spans from the left engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your BMW X5/X6! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

FEATURES

Direct-fit replacement and upgrade for E70 X5 and E71 X6 applications Solves intermittent grounding issues caused by aging OEM straps Clean, stealthy design that fits seamlessly in factory engine bays Factory length and lug orientation for drop-in fitment 2 AWG tinned copper cable for excellent conductivity and corrosion resistance Zinc-coated lugs, crimped and soldered to resist moisture and oxidation Black UL1015-grade insulation withstands oil, heat, and abrasion Discreet ECS label for a clean, OEM+ look Replaces OEM part number 12427557027.

The main reason all of the VANOS units will eventually fail is because the material used for the sealing rings from the factory is not designed for that type of environment. When this happens the only option that BMW leaves you with is buying a new and expensive VANOS unit with the same sealing rings that failed in your original unit.

The VANOS system found in BMW engines is a great feature (when it’s working properly), keeping your power curve smooth and responsive especially in lower to mid RPM range. What usually goes unnoticed is the gradual loss of power within this range as the vehicle's age due to slowly failing seals within the VANOS unit. The way the VANOS system works is based off of oil pressure triggered by a solenoid that allows for a small range of timing degree adjustment, this is where the power curve is affected. When the seals begin to fail (all of them do) there is less pressure to advance the timing reducing the power in that low to mid range. Because this happens slowly it's very hard to notice a difference until you refresh your VANOS unit, then you easily realize the response you've been missing.

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

While you're replacing the seals in your VANOS unit it a good time to install anti-rattle spacers to tighten up the gaps in your stock assembly and get rid of that noisy VANOS clatter.

Seals & O-rings:

The seals  were the main focus of this project since the OE units are built with Buna-N rubber o-rings instead of the ECS supplied Viton rubber o-rings. The Buna-N material quickly hardens from the heat and chemical exposure within the engine, where the Viton is significantly more resistant to these chemicals. This knowledge was also used when it came to the commonly failed o-rings found on the VANOS seal plate, replaced at the solenoid.

Rattle Repair:

When it comes to the VANOS rattle this is commonly described as "marbles in a can", and can be heard throughout the different RPM ranges depending on the engine. These upgraded rings and washers are precision ground from hardened steel to resist wear and deformation keeping your VANOS rattle free. The rattle repair tools are designed specifically for this VANOS anti-rattle repair, design from hardened steel to stand up to the job. Designed to perfectly follow the splines of the shaft for a tight grip when applying the necessary torque to disassemble & reassemble the VANOS transfer gear. The keyed socket was designed with the intent to use a "common" wrench so this can be completed at home in your garage.    

When Servicing your VANOS unit we recommend getting everything you need to replace on the way to service which includes an oil change and valve cover gasket set. Fresh oil and gaskets is the best way to start off a fresh rebuild of any kind giving you the maximum performance of your freshly serviced components.

Don't forget to check out our rebuild PDF to make sure you have everything to get the job done and eliminate the rebuild guess work.

All-in-one valve cover overhaul Preventative replacement saves time and trouble later on Includes new oil separator system Replace valve cover gaskets before a leak becomes worse Replace valve cover before it cracks For the 2007 model year BMW switched to a plastic valve cover on the N51 and N52 engines. As we have seen over time the plastic can crack which leads to oil leaks, vacuum leaks, poor running, and other issues. Unfortunately, it's not just the gasket that needs periodic replacement but the entire valve cover itself. This kit includes a new valve cover, gaskets, eccentric shaft seal, and hardware. The valve cover also incorporates the oil separator which is not a replaceable item on its own. So a complete valve cover replacement will tackle multiple problem areas at once. The valve cover is the same for N51 SULEV and N52 engines. Cracked Valve Cover. The plastic used for the N52 valve cover is thin and weak in certain spots. This makes it prone to hairline or larger cracks that will leak oil and cause vacuum leaks. You might also notice rough running, especially at idle. Often a technician will go looking for a failed ignition coil, spark plug, or failed vacuum hose on the engine. And without a fault code to assist in diagnosis this can often mean wasted time and money. A cracked valve cover is a new problem area that many techs don't think to check. Oil Separator/Crankcase Vent. BMW integrated the oil separator system into the valve cover on these later engines. An internal manifold creates a cyclone effect and centrifugal force separates vapor from the liquid oil. The liquid oil is supposed to drain through the valve cover and back to the oil pan while the remaining vapor is burned up during combustion. It's a very efficient and environmentally-friendly design with very few moving parts. Unfortunately it's not perfect and eventually the internal passageways will become clogged. This problem is made worse in cars that have short drive cycles, sit for long periods of time, do not have frequent oil changes, do not see regular runs to redline, and cars in freezing climates. If the engine never reaches optimal operating temp the oil remains in liquid form or becomes sludge. This is bad news for the entire engine, leading to fouled spark plugs, rough running and misfires and even premature failure of catalytic converters and oxygen sensors. Since the oil separator system in the valve cover is not available on its own, and cleaning it is nearly impossible, the complete replacement of the valve cover is the only option. Other oil vent tubes and vacuum hoses are also recommended to get replaced at the same time. Valve Cover Gaskets. As with any rubber part, failures occur when the rubber becomes dry and brittle. The pliable rubber no longer forms a seal between the cylinder head and valve cover where it will develop an oil leak. Valve cover gaskets that leak can allow oil to seep into the spark plug holes and contaminate ignition coil boots and plugs. That can lead to rough running and misfires. A new valve cover includes new gaskets. Eccentric Shaft Seal. The seal for the eccentric shaft sensor is a known spot for oil leaks. When the seal to the valve cover fails oil can end up in the sensor itself and ruin the sensor (an unecessary $300 expense). Usually a new seal (o-ring) will stop the leaks but sometimes the valve cover is at fault too. A new eccentric shaft seal is included. All new hardware is included to avoid re-using and over-tightening the original bolts (they have a very low torque rating). Replacement requires accessing the rear of the engine with a lot of the upper plastic shrouding removed. The vent hose on the valve cover should be replaced as it is almost always broken anyway (#11157559528). The metal fuel line must also be removed and disconnected from the fuel injectors. Professional installation is encouraged if you have never done this kind of work before. Serious DIY types should have a Bentley Service Manual to use which greatly explains the process. You may also want to combine this work with the oil filter housing gasket replacement. There is no maintenance or replacement interval for the N52 valve cover. However, we have seen cracks and other failures in the 50,000-90,000 mile range. Our best advice is to plan on a major top end overhaul around the 70-80,000 mile mark. There's no mechanical downside to replacing it as prevention and it will make the engine run better and last longer.

For Alternator / Water Pump Belt

Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.
