BMW B58 Engine Oil Filter Housing Replacement Kit - 11428583895KT

BMW's B58 engine has shown itself to be a robust and reliable engine across numerous platforms. However, nothing is perfect. One engineering decision BMW decided to make was constructing the oil filter housing from a plastic composite. One thing that seems to be a common theme when plastic composites are used is they tend to fail in the long run.

The oil filter housing on the B58 engine over time has shown itself to be a major weak point. There are a few common failure modes:

• Oil filters breaking inside the oil filter housing (noted in SIB 11 01 20)
• Broken housing due to overtightening of oil filter cap
• Leaking from perimeters of oil filter housing
• Coolant and oil mixing due to cross-contamination from the degradation of the oil filter housing

In any of the above cases, the oil filter housing is going to need to be replaced as an entire assembly. To perform this job you are going to need to remove the intake manifold/charge cooler assembly, strut tower reinforcement brace, and a whole bunch of plumbing. This kit includes all the base components you will need to replace the oil filter housing as an entire assembly. The replacement oil filter housing includes the oil filter housing gasket set, p/n 11428583896, engine oil cooler seal set, p/n 11428583897, oil filter, p/n 11428583898, and oil filter cap, p/n 11428583900.

This kit is intended for automatic transmission vehicles. You will need to check the fill level and add transmission fluid to the automatic transmission because the trans cooler system needs to be opened. You will want to order an 8HP compatible transmission fluid, G48 (Blue) or HT12 (Green) antifreeze depending on your vehicle and what coolant fill it has, plus your choice of 7 liters of engine oil (see recommended items for suggestions).
