Includes a full set of polyacrylic intake and viton exhaust valve stem seals! Looking to replace your valve stem seals due to leaks, cracks, splits, or even during an upgrade of your camshafts, valve springs, or valves? Supertech valve stem seals are the way to go! This cheap but effective seal replaces the stock BMW seals that are notoriously prone to issues due to heat cycles and chemicals which cause the seals to become weak and brittle. Supertech seals offer a significantly longer life span and are resistant to both heat and chemicals thanks to their use of Viton or Polyacrylic construction (dependant on valve type). That means less time in the garage and more time on the street or track! These seals are also great for anyone who is looking to upgrade to dual valve springs thanks to the seal's overall thinner outer diameter! Guide OD: 8.8mm/.347" Seal OD: 12.2mm/.480"

The roller rocker arms transfer the rotational force of the camshaft to open the intake and exhaust valves. One end is raised and lowered by the rotating lobe of the camshaft, while the other end acts on the associated valve stem. If a roller rocker arm has failed you may experience a constant ticking noise during engine operation, or alternatively if the rocker arm has broken, you will receive multiple misfires and a rough running engine.

If there is one weak point to the internals of the M20 engine, it's the camshaft rocker arms. They're actually designed to be the weak link to prevent more extensive damage elsewhere in the valvetrain. The rocker arm actuates the valves as the cam lobe makes contact. But sustained running at high RPM will cause the valves to 'float' or stay open which can lead to contact between the piston and the valves. If this happens too often, it will fatigue and snap the rocker arm. Therefore, any track driven E30 should have the rockers inspected or replaced often, along with a correct valve adjustment. And any high mileage M20 engine is running the risk of failure because of fatigue and weak valve springs. It's also a good idea to use new rocker arms any time a new cam is installed as the cam and the rocker wear together.

Replacement of the rocker arms can be done with the cylinder head in the car but more often, the head is removed. This makes removing the rocker shafts easier. Either way, a new cylinder head gasket set is recommended as it includes all of the gaskets and plugs that you would need. If the head stays on the car, the radiator may need to be removed to allow more access for the shafts to come out. Replacing the engine timing belt is not done at the same time and should be treated as a separate job.

These Febi M20 rocker arms are sold per rocker (order 12 for a complete set). You may also want to replace the eccentric adjusters as it's easy to do and worn eccentrics may prevent you from properly adjusting the valves afterward.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

Maintaining the peak performance and reliability of your BMW N52 engine is essential for a smooth and enjoyable driving experience. One of the most effective ways to achieve this is by replacing critical components like the valve cover, crankcase vent hose, angle connector with heating element, and cylinder sleeve. In this article, we'll delve into the numerous benefits of upgrading these vital parts, ensuring your BMW N52 operates at its best. Optimized Engine Performance: Replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve enhances your BMW N52's engine performance. The valve cover plays a crucial role in sealing the engine, preventing oil leaks and ensuring optimal valve operation. When you upgrade these components, you reduce the risk of performance-robbing oil leaks and maintain precise valve timing, resulting in improved horsepower and torque. Enhanced Reliability: Reliability is paramount for any BMW owner. These components, when aged or damaged, can lead to severe engine issues. By replacing them, you significantly reduce the likelihood of unexpected breakdowns or costly repairs, ensuring your BMW N52 engine runs smoothly and reliably for years to come. Improved Fuel Efficiency: An efficiently operating engine not only performs better but also consumes less fuel. The replacement of these components leads to better combustion, reduced emissions, and ultimately improved fuel efficiency. This means fewer trips to the gas station and a lighter environmental footprint. Reduced Maintenance Costs: Regular maintenance and repairs can add up over time. By proactively replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve, you mitigate the risk of more extensive engine damage that could lead to expensive repairs down the road. In the long term, this can translate into significant cost savings. Extended Engine Lifespan: The longevity of your BMW N52 engine is directly tied to the quality and condition of its components. When you invest in high-quality replacements, you're effectively extending the lifespan of your engine. This not only preserves the value of your BMW but also allows you to enjoy its performance for years to come. Precise Temperature Control: The angle connector with heating element is vital for maintaining optimal engine temperature, especially in cold weather. A malfunctioning or worn-out connector can disrupt temperature control, affecting engine performance. Replacing this component ensures consistent and precise temperature management. Customized Upgrades: When replacing these components, you have the opportunity to choose high-performance or specialized alternatives, allowing you to customize your BMW N52 to your preferences. Whether you prioritize power, efficiency, or specific driving conditions, there are options available to tailor your engine's performance accordingly. Included in the BMW N52 Valve Cover & PCV Valve Refresh Kit: 6 Cylinder Sleeves 1 Alternator Mounting Screw Set 1 Angle Connector with Heating Element 1 Valve Cover - Gasket Included 1 Crankcase Vent Hose

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. Kit includes Upper and lower WPC treated rod bearings for extra protection against wear Hardware Oil filter Castrol TWS Edge Professional Oil pan gasket Oil pan cover gasket RedLine assembly lube Connecting rod bolts

The S85 engine has a known history of rod bearing failure. If your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing, a failure that has the potential to trash your crankshaft.

What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or rod bearing service!

Kit Includes:

Turner Motorsport "Race Series" WPC-Treated Rod Bearing Shells (20) Genuine BMW Connecting Rod Bolts (20) OEM MANN Oil Filter Kit Castrol Edge Euro Car Engine Oil (10w-60) - 9 Quarts Genuine BMW Oil Drain Plug Turner Oil Change Decal Elring Oil Pan Gasket Permatex Ultra Slick Engine Assembly Lube (4 oz.)

BE Bearings, in conjunction with Clevite, an OE bearing manufacturer, have redesigned and manufactured the bearings for greater clearance and have changed the original material composition from tin-aluminum to lead-copper. This upgrade incorporated the state-of-the-art Clevite Tri-Metal design and featured a Tri-Armor™ coating. This allows for the additional lubrication for wear prevention, plus, the softer bearings are better for your engine and are more tolerant of foreign particles suspended in your oil. Another benefit from this is that the oil can now be sent for testing to accurately gauge the amount of wear occurring in the engine.

Anyone with a modified N54 knows the risks involved. Upping the performance of any engine can come with some inherent risk; if we add more boost but not fuel, detonation will occur (or worse). Furthermore, improper installation, maintenance, or operation can turn a perfectly healthy engine into a paperweight. The worst failures, however, are the ones we don't plan for. When the engine simply can't handle the stresses its put under, or the design is such that it simply does not support extreme conditions. Enter the N54 crank hub. Under certain conditions, it likes to spin without warning, even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines that press into the crank and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Vargas spent many months testing, and retesting this design, utilizing well over 10 different samples to come to the final production version. During testing, the final hub managed to break the testing rig before slipping. These have been bench-tested, and real-world tested on the VTT N54 race car spinning 8K RPM, and making well over 900WHP. Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and Turner Motorsport are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our intake valves are made exclusively from an enhanced versions of EV8 (21-4N) steel. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Black Nitride Coating Head Diam: 33mm Material: Stainless Steel 21-4N Groove Type: Triple Groove Length: 123.7mm Stem Diam: 6.95mm
