Why do I need to replace my breather cover?
Air leaks in the breather hoses will bypass the filter (think sand in your engine) and unmetered air will bypass the MAF and affect mileage. If you are thinking of just replacing the RTV – it is more than likely that the hardened and brittle breather hoses will crumble in the replacement process and need to be replaced.
What are the drawbacks of valve and breather covers?
(Valve and breather covers are sold together. $100 used replacement with no guarantee of condition – $400 for a new replacement.) Another drawback of magnesium is that it is more susceptible to general and galvanic corrosion. Magnesium corrosion is more pronounced than in Aluminum.
Why is the breather cover on the driver side longer?
The breather cover on the driver’s side is longer to separate entrained additional oil from crankcase gases before being sucked into the air intake. For this reason, the driver side breather cover also has 3 oil drain ports to help minimize oil consumption at the intake.
What is the part number for a valve cover gasket?
– 5 stainless steel replacement bolts to replace the aluminum – Old Part number 000912-005010, M5x18 superceded by new Part number 000000004436. A MB valve cover gasket should come with a cardboard backing and already be laid out to relax in its final form.
