Valve cover breather

Lou1119 · #1 (**permalink**) 08-23-2017, 09:53 AM

I'm preparing for the last show of the year and I need some help. The motor in my car is a Roush 427SR and has the normal chrome valve cover breather on the driver side. I realize that it is a breather but the oil that leaks out drives me crazy especially when I drive the car to a show. I have tried the old hot rod trick of cutting a piece of sponge the size of the breather and placing it between the valve cover and the breather itself. It is like a doughnut with a hole in the middle to let the neck slip through. This works OK if the car is not driven too far but on longer trips I still get the leakage once the sponge gets saturated. Does anyone have another soloution?

Thanks

I run breathers on both valve covers that have the exposed pleated filter element and I just made some gaskets for the sealing surface out of some 1/8" neoprene rubber. The gaskets are about a 95% solution to the oil seepage.

I did a very similar fix as Shootnride.

Are you running a PCV setup? If not that would most likely take care of the problem.
