The engine crankcase in you car is filled with oil to keep everything lubricated, and to keep the oil inside of the engine, seals are used anywhere there is a seam in the engine, or any place a shaft protrudes from the engine. One such seal is the front main crankshaft seal. This seal is located around the the crankshaft at the front of the engine, and keeps oil from leaking out around the crankshaft. Unfortunately, over time seals will become brittle, crack and begin to leak due to their exposure to heat and oil.

The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).

The Schwaben Piston Ring Filer is a vital tool for obtaining the precise end gap necessary for optimal piston ring performance.

This filer allows you to swiftly and accurately file piston rings to exact measurements, enhancing your engine’s efficiency and lifespan. By simply positioning the piston ring and turning the handle, you can easily rotate the abrasive wheel for a smooth and effective filing process.

**Note:** For the Schwaben Universal Piston Ring Compressor, check out T25805755!


Key Features:

  • Optimize Performance: Achieve the perfect end gap crucial for top engine efficiency.
  • Quick and Precise: File rings to exact specifications with ease.
  • Easy Operation: Position the piston ring and turn the handle to effortlessly rotate the abrasive wheel.
  • Enhanced Engine Longevity: Accurate end gaps contribute to longer engine life and better performance.


Instructions:

1. Position the Ring: Place the piston ring on the outer edge against the stop and align the ends squarely against the grinding wheel. Apply light, even pressure against the wheel to prevent grinding too large a gap.
2. Operate the Tool: Turn the handle so the grinding wheel turns towards the inside edge of the ring (counter-clockwise when viewed from the handle side of the tool).
3. Exercise Caution: This is a diamond grinding wheel. It cuts fast!

Checking Piston Ring Gap:

1. Deburr the Ring Ends: Carefully remove any burrs on the ring ends before placing the ring in the bore. A light touch with a fine abrasive stone works well.
2. Clean the Rings: Thoroughly clean the rings with lacquer thinner or acetone, as the paint coating from the factory may occasionally scratch the cylinder bore. Always wear gloves during this process.
3. Position the Ring in the Cylinder: Place the ring squarely in the cylinder bore, about 1" down from the deck surface. An upside-down flat-top piston will help you properly square the ring.
4. Measure the End Gap: Use a feeler gauge to measure the ring's end gap. Apply light grinding pressure and check frequently to avoid making the end gap too large.

The best solution for 24v Swapped E30's using an M50, M52, S50, S52US, S54, or Euro S50 Engine with the E34 525i M50 oil pan! The Achilles Motorsports Oil Pan Baffle was designed and manufactured to be used on racing, high-performance track, and street driven cars. Each baffle is precision laser cut from .090" heat-treated aluminum then hand-assembled and test fit to ensure accuracy and ease of installation. Achilles Motorsports' baffle design incorporates dual trap doors and a unique oil deflector that prevents oil from splashing out of the sump under hard braking. Together, these help minimize the sloshing of the oil inside the oil pan and keep oil accumulated around your pickup tube. The factory BMW oil pan doesn't do a very good job of keeping oil accumulated around the oil pick-up tube in high g-force situations. By keeping oil accumulated around the pickup tube you can eliminate the costly loss of oil pressure and potential damage to other vital engine parts commonly caused by high g-forces from hard acceleration and braking and high-speed cornering. Professional welding is required for installation!

This is the voltage regulator found on the back of the alternator. It's a normal wear item and the contacts are the first thing to check if you believe the alternator is not charging the battery (lights flickering or dim, battery light on in the dash, the engine quits without warning, or other electrical failures). The voltage regulator manages the voltage flowing through the car, especially to and from the battery. There are two carbon contacts on the regulator that control the magnetic field when the alternator is spinning and these contacts wear over time. A new set of contacts will be about 13mm in length. Anything less than 5mm and the voltage regulator should be replaced, regardless if that is the cause of your electrical problems or not. Most older mechanics will tell you to keep a spare regulator in your toolbox.

The carbon contacts can be replaced on their own but requires desoldering the old ones from the base and then soldering the new ones on. It may be easier to just replace the unit as a whole.

This is the OEM voltage regulator, made by Bosch or Hella. It's the one with the white base and fits most Bosch alternators from 1977-1995 (Valeo and other alternators look very different and have a black cover and base). This part number replaces the previous BMW part numbers - 12311271664, 12321279548, 12311722755, 12321711399 and Bosch part numbers 1197311021 and 1197311028.

When building a car for the track, one of the most important factors to consider is weight. Stock batteries can weigh up to almost 50 pounds and are unnecessarily large, designed to power a host of systems not normally used in a track car (radios, lighting, etc.). What can you do to cut weight the weight without affecting your car's operation? This is where Braille Battery comes in with their long line of performance lightweight battery options! Designed to provide the highest cranking power possible while being up to 75% lighter, Braille Battery is one of the foremost leaders in automotive racing batteries with nothing but high quality, high output batteries in mind! The B3121 battery from Braille is their lightest do-everything battery available, offering 1380 pulse cranking amps that can crank over V8 engines with ease while still coming in at under 22 pounds, half of the weight of a standard Group 34 battery! This is thanks to their Advanced AGM racing technology that allows them to put a ton of power into a very small package. Physical Specifications: BCI Group: All sizes Weight: 21lbs / 9.5kg Length: 6.6" / 168mm Width: 5.2" / 132mm Height: 6.8" / 173mm Polarity: Right Side Positive Terminal Type: Steel terminal block with M6 bolt Performance Specifications: Voltage: 12v Recharge Voltage: 14.4V – 14.6V Maintenance charge voltage: 13.8V 5s Pulse Cranking Amps (PCA): 1380 10s PDC: 124 Amp Hour (Ah): 31 Watt Hour (Wh): 372 Life Cycle @ 10% DOD: 3100 Charging Temperature 0C to 50C Discharge Temperature range -40C to +60C Storage temperature -40C to +60C *THIS BATTERY REQUIRES A CUSTOM MOUNTING SOLUTION. The size and weight are significantly smaller than a stock battery and will not be held in place by the stock battery mount*

This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.

This set of OEM gaskets covers everything you might need when re-sealing the bottom-end of the E30 M3's S14 engine. Using a complete gasket set will save you time and money if you have the engine out of the car and are performing any major repairs with the oil pan and timing covers off the motor. This is the correct S14 bottom-end gasket set, not a re-packaged M10 kit.

This set of gaskets is a both a time and money saver. It includes all of the commonly replaced gaskets, seals, and o-rings when performing this overhaul. Having these on hand instead of chasing them down at the last minute will save you time, money, and frustration. With this area of the engine apart you're going to want or need to replace these items anyway to ensure it's free of fluid and vacuum leaks. This is especially important because some states have very strict emissions regulations and vacuum and oil leaks can lead to failed inspections tests. On newer cars this can also create issues in the on-board diagnostics system. Even if you're not pulling the head this set includes so many valuable parts you'll want to keep this on hand to use for spares.

With more than 100 years in the industry, Elring is one of the oldest names in the European autoparts segment. Delivering OE-quality you can rest assured the job will be done right the first time.

Designing the ultimate BMW E30 Oil Cooler was not an easy task. While with custom fabrication anything is possible, CSF prides itself on making upgraded products that fit like a factory unit. Fortunately, BMW already did some of the leg work for this in the late 1980s. The new CSF #8218 is based on the race-proven and championship-winning formula used by BMW. To give you some history on this topic, we have to go back to 1987. After BMW decided to enter Touring Car and DTM racing, they created what most would consider to be the ultimate E30 M3. In the span of about 5 years, the Group A spec M3 became the most successful touring car of all time. This race-spec BMW won two champion’s titles in the European Touring Car Championship and German Touring Car Championship (aka DTM) and countless other victories. The BMW Engineers had to design an oil cooler that could keep up with the added power of the race-spec engine and perform under the grueling conditions on the track. The size of the standard factory oil cooler was increased by about 50% while using the same mounts and connectors as the standard production M3. The CSF E30 Group A / DTM Race Style Oil Cooler is the same size as these race coolers with some modern upgrades/updates. While your original system may still be functional, it is likely not in the best shape. Dented, clogged, and weathered coolers just can’t perform like a new cooler. Even then, the old tube and fin design don’t compare to the durability and performance of a bar and plate design. CSF understands that most owners don’t want to change the look of their Bavarian classics at this point. That’s why the E30 Group A / DTM Oil Cooler was design to fit in the factory location with no custom mounting hardware necessary. The CSF Oil Cooler offers superior cooling capacity, modern technology, and costs less than a genuine OE replacement. When designing this new cooler, CSF wanted to ensure the best possible performance while ensuring the cooler was as durable as possible. As you’ve seen, oil coolers and other heat exchangers can take quite a beating over time. CSF utilizes an extremely rugged and durable Bar/Plate design that can stand up to far more abuse. The CSF “Aero-Flow” Bar design reduces weight compared to other Bar/Plate designs while maintaining maximum strength and air flow. These “Aero-Flow” bars improve heat dissipation with high-density turbulated multi-louvered fins. Turbulation increases the turbulent flow through a tube, effectively increasing heat exchange rates and abilities. At around 50% larger in size, the CSF #8218 Oil Cooler increases both fluid capacity and core surface area. The overall performance of the Oil Cooler far exceeds the factory cooler’s limits. 100% All-Aluminum construction ensures the best performance and durability. In addition, the black powder coat finish provides extra protection and offers an OEM look behind the grille of your E30. Features & Specifications: Group A / DTM E30 M3 Oil Cooler Design Direct fit oil cooler for BMW E30 M3 Can fit all E30 Chassis (see applications and fitment notes) High Efficiency & Rugged Durability Bar/Plate Design “Aero-Flow” Bar Lightweight Construction for Strength and Maximum Flow Cast End Tanks with 100% Tig Welded Construction Satin Black Finish for Extreme Protection Against Corrosion and Debris Comes complete with fitting kit for both OEM style as well as -10 AN male connections Fitment Notes: 1986-1993 BMW E30 M3 (S14) The long factory oil hard line will not be able to use support brackets on the back of the radiator. This is due to the adapter fittings pushing the lines out about a ½” from factory so the brackets won’t line up but the lines will still run to the proper location and can be connected. 1985-1987 (up to 09/87) BMW E30 325 w/ Factory Oil Cooler Requires custom lines (factory hard line passes over the oil cooler normally but this unit is too tall to run that line over the top). 1988-1993 BMW E30 325 w/ Factory Oil Cooler Requires custom lines & mounting hardware. E30 Chassis has provisions for OEM mounting hardware.
