Oil Dipstick Tube O-Ring, 19.5x3, Rein - E36, E39, Z3, Z4, M52 M54 S52

If you remove the dipstick tube on M52, M52TU, M54, or S52 engines this o-ring on the oil pan should be replaced. Removing the dipstick tube is common because it can become blocked with sludge or solids from the crankcase vent valve. Re-using the o-ring is not a good idea because it hardens and shrinks over time, which can cause a small leak.

This is a o-ring manufactured by Rein (CRP) Automotive - the original supplier to BMW for this part, as well as many other seals and gaskets. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
