Porsche Cayenne valve cover breather diaphragm with 4.5L V8 engine (2003 - 2010) M48.50, M48.00 engine
The membrane must be selected according to the original valve cover number, since the original membrane is not supplied separately!
The original valve cover number for the piston is 94810513107, 94810513206, 94810513207
Problem situations caused by improper functioning of the OECS on the Porsche Cayenne are not uncommon. The vast majority of failures are caused by a worn rubber membrane. According to the design features of the valve, it is constantly in contact with the oily medium and the settling emulsion formed during gas condensation has a detrimental effect. As a result, the base loses its inherent elasticity, coarsens, cracks and bursts.
The consequence of a worn out membrane is the inaccessibility of pressure equalization in the crankcase, overspending and oil leakage, and a decrease in acceleration dynamics. The first symptoms are a kind of whistling sound in the area of the oil separator and choppy idle. If a damaged membrane is found, replacement should be carried out immediately without aggravating the situation.
The manufacturer’s membrane is conceived as a structurally integral part of the cover and, accordingly, is not supplied separately to the market for component parts. The acquisition of an entire valve cover due to an unsuitable membrane is an absurd idea due to its high cost. Our company corrected this deliberate flaw and set up the sale of a separate KVKG membrane valve cover with the original number 94810513107 for Porsche Cayenne v8 4.5L M48.50 M48.00
