How can the rear crankshaft seal be replaced after removing the transmission and flywheel on BMW M3?

The crankshaft seal can be replaced after the transmission and flywheel have been removed from the engine. Note the radio security code and disconnect the negative battery cable. Raise and safely support the vehicle. Remove the transmission. On manual transmissions, remove the clutch assembly. Remove the flywheel. Using a suitable seal removal tool, carefully remove the oil seal. Inspect the outer edge of the seal housing for nicks or sharp edges. Carefully chamfer the outer edge of the seal housing to remove any sharp edges or nicks. Coat the sealing lips of the new seal with oil and install the new seal into the end cover housing with a suitable seal installation tool. DO NOT coat the outer sealing surface of the seal with sealant. It should be clean and dry on the 6-cylinder engines. Press the seal in until it is about 0.039-0.079 inches (0.991-2.070mm) deeper than the standard seal which was installed flush with the housing. Install the remaining components in the opposite order from which they were removed. Lower the vehicle and connect the negative battery cable. Check and top off all fluid levels. Once the engine is started, check for any fluid leaks. Start the engine and check that oil pressure is present; if the oil pressure lamp does not extinguish within 5-7 seconds of starting the engine, turn the engine OFF.

BMW M3 Crankshaft Seal

The BMW M3 Crankshaft Seal helps retain essential engine oils while preventing road grit entry, protecting performance across all rpm. Both sides of the crankshaft are fitted with a Crankshaft Seal to form a tough pressure wall that is capable of handling daily commuting rides and weekend track abuse. The BMW powerplant is free to turn without leaking thanks to its fluoroelastomer or nitrile lip, tightened by a garter spring that grips the journal. The Crankshaft Seal has micro grooves that direct excess oil into the sump, reducing losses and increasing efficiency. Thanks to this smart oil return feature, there is also less chance of vapor near hot exhaust components, which protects the driver and the passengers. Any M3 generation part, be it an E30 or today's turbos, can last with the help of heat resistance and chemical toughness. Because the Crankshaft Seal utilizes the one seal format, the owner can easily swap it in and get back to factory specs. Fitment covers all six official M3 eras, which include coupe, sedan, wagon, and convertible with one solution. The Crankshaft Seal's consistent lubrication cushions bearings, maintains cam timing, and regulates temperatures, ensuring that the BMW emblem remains synonymous with endurance. The Crankshaft Seal contains self-cleaning lips and balanced springs that do not relax through repeated heat cycles, even on ordinary seals. BMW recommends regular intervals for oiling the M3 system. Installing a new seal takes basic tools. This focused upgrade provided to any M3 owner ensures that they enjoy the authentic BMW experience of worry-free speed together with daily dependability. The loyal M3 community can now live the BMW performance experience mile after mile.

In addition, we have a hassle-free return policy on all genuine BMW M3 Crankshaft Seal that come backed by the manufacturer's warranty.
