Crankcase Oil Separator Hose to Dipstick Tube, CRP - E36, E39, Z3, M52, S52

This hose runs from the crankcase vent valve to the dipstick on M52 and S52 engines. Over time the crankcase vent (CCV) hoses become clogged with sludge, especially in colder climates, and a fresh hose is necessary to avoid major problems down the road.

This is a oil return hose manufactured by Rein (CRP) Automotive - the original supplier to BMW for this part, as well as many other engine hoses and lines. 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.
