M56 Valve Cover Vent Hose, Rein - E46 325i M56 SULEV

This is the crankcase vent hose that takes oil vapor from the M56 valve cover and redirects it back into the intake manifold on 2003-2005 E46 325i models with the M56 SULEV engine. Unlike the standard M54 engine, the M56 has its crankcase vent system contained in the valve cover. The only hose to replace is this one running from the valve cover to the manifold. This hose can become clogged with oil sludge if the vent valve is not functioning properly. And the plastic connectors at both ends are known to be weak and break when removed.

This is an OEM M56 vent hose manufactured by Rein Automotive - an original supplier to BMW for many hoses and engine components. As an 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.
