Rod Bearing Overhaul Kit (Basic), WPC Bearings - E90 E92 E93 M3

Product Description

• WPC-treated BMW rod bearings and hardware
• OEM gaskets
• Rod Bolt Options: ARP or Original BMW
• Your choice of engine oil with an OEM filter

Rod bearing replacement is a fact of life for any E9X M3 owner and this kit has you covered for a DIY rod bearing replacement on the S65 engine. This package uses the latest Genuine BMW rod bearings that have gone through a micro-polishing treatment by WPC. This process is a shot-peening of the metal at a microscopic level that removes high spots and imperfections, which increases surface retention for oil and improves fatigue resistance.

From the menu above you can select the engine oil to include in your kit: Genuine BMW 10W60, Red Line 15W50, or no oil (you supply your own).
- Genuine BMW oil is obviously the factory recommendation and its the latest TwinPower formula
- Red Line 15W50 is our preference because of the research we have done. Even though classified as an SAE 15W it's actually thinner when cold than the factory 10W. This allows easier access to tight bearing clearances and faster warm-up temps. The SAE 50 rating is lower than the factory oil but the Red Line has greater shear strength and lower evaporation than the factory 60 oil. We feel that the RL 15W50 is a better overall choice for street and mildly-tracked M3s and it's what we use in our own cars.

Genuine and OEM gaskets and o-rings are included.

Important Notes:
Note 1: front subframe must be removed (lowered) to access oil pan and bearings. This creates multiple opportunities to replace other parts. This kit only includes the crush washers for disconnecting power steering lines to lower the subframe and steering rack. Contact us for a "Extended" kit that covers more parts.
Note 2: BMW calls for a set of new oil pan bolts when removing the oil pan. We don't feel this is necessary and have re-used these M6 bolts multiple times. We do offer a replacement set, see the Related Items link below.
Note 3: when engine re-assembly is complete, prime the engine with the fuel system deactivated. Priming is done by engine cranking without firing and allows oil to circulate to critical areas.
Note 4: Correct oil operating temperature is 220°F - you should properly warm your engine before subjecting it to higher throttle angles and RPM.
