BMW Engine Parts for BMW 3 Series E46 (1999-2005)

Maintaining optimal engine oil levels is crucial for peak performance in your BMW. Leaks can occur between oil change intervals, leading to dangerously low oil levels. The valve cover is a frequent culprit for such leaks due to gasket degradation from years of exposure to temperature fluctuations. Replace your valve cover to ensure the retention of engine oil within your vehicle.

Key benefits of replacing the valve cover include:

• Preventing oil leaks that could lead to low oil levels.
• Preserving engine performance and longevity.
• Avoiding potential engine damage from insufficient oil.

Ensure your BMW's engine operates smoothly by replacing the valve cover to contain the engine oil effectively.

If there is a large amount of oil on the sides of the engine or if you can smell burning oil, chances are it's a bad valve cover gasket. The gasket fails and allows oil to seep down onto the side of the engine and other parts causing a mess and reducing the amount of oil in your engine. This replacement gasket from Elring is perfect to prevent any further oil leaks.

Includes the following Seals:

• Valve cover gasket
• Spark plug seals
• Nut seals
• Grommets

Elevate your custom installation with the ECS -10AN O-Ring Boss fitting, a crucial component that connects your ECS Tuning Catch Can to a 3/4" ID hose. This fitting simplifies your plumbing setup, ensuring a seamless solution.

Featuring a pre-installed Viton O-ring, this fitting is engineered for excellence, providing a leak-proof seal that resists the effects of oil and fuel exposure, guaranteeing long-term durability.

The 3/4" nipple is thoughtfully designed with barbs to secure hose position effectively, minimizing the risk of hose disconnection. Keep in mind that clamps and hoses are available for separate purchase. These fittings are sold individually, with most installations requiring a pair of them.

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability.

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking. 

After the introduction of the M52TU/M54 engines, BMW observed an uptick in CCV-related issues, especially in cold regions. Vehicles operating in extremely low temperatures often encountered a blockage in the CCV dipstick hose, leading to elevated crankcase pressure and visible blue smoke from the exhaust. To address this issue, BMW introduced cold climate-specific hoses with foam insulation, preventing condensation and facilitating quicker oil warm-up. This kit incorporates top-notch reproduction cold climate hoses to ensure optimal CCV performance across all weather conditions.

The crankcase ventilation valve, known as the oil separator, PCV, CCV, or crankcase pressure regulator valve, plays a vital role in redirecting oil from your vehicle's intake system back into the engine oil pan. This system comprises numerous plastic and rubber hoses, prone to damage due to prolonged exposure to chemicals and heat.

Designed to tackle or prevent impending CCV system failures, this kit includes four foam-insulated hoses made from durable plastic capable of withstanding heat fluctuations and chemical exposure. Additionally, a new ventilation valve is included for a comprehensive and long-lasting repair solution.

Signs indicating the need for crankcase ventilation system replacement include:

Whistling sounds from the intake manifold, caused by crankcase pressure venting through holes in the CCV hoses. Blue smoke emitting from the tailpipe, indicating oil consumption. Excessive oil usage. Milky or yellowish buildup under the oil cap, suggesting condensation due to ventilation valve malfunction. If you're experiencing misfires, lean fuel codes, decreased fuel efficiency, or noticeable oil consumption, it's advisable to overhaul your crankcase ventilation system. Opt for this reliable system from Febi-Bilstein for a repair that meets factory standards and ensures consistent performance.

A beautiful addition and durable upgrade for your engine

Sometimes you have to take the cylinder head off of your vehicle to diagnose problems, have it rebuilt, or replace a faulty head gasket. It tends to be a fairly labor intensive job, so anytime you can make it easier is definitely helpful.

When it comes time for reassembly, one of the biggest problems is finding quality gaskets and seals. Turner has your solution with this cylinder head gasket kit. With so many gaskets that are one use only to replace, getting them all done at the same time can be made harder by not having everything you need. With the proper, high quality gaskets, your reassembly will go much easier with no need for trip after trip to the local auto parts stores. Intake, exhaust, downpipe, valve cover, and in some applications valve seals will all help to get your engine into top condition.

When it's time to put everything back together, there are some things that should not be overlooked. Most cylinder head fasteners found on European automobiles are a one time use or stretch bolt. To be sure that everything is tightened down properly, it is important to replace them to get the proper torque reading and ensure the longevity of your repair.
