Hello, my name is Brandon and I just bought my first MB, it an 1988 300E and there ia a check valve that I need to replace but can not seem to find anyone that knows what it is. It is a small check valve on the right top side of the motor that has a vacuum hose running each side. It is not the vacuum check valve because I found that one (Yellow 2 on 1 side 1 on the other). This one is white and almost looks like 2 cones put together with about a 1/4 hose on each side. It is running from under the air filter to what says GRIGGLE or something like that on it ( like the steering column. If anyone knows what valve I am talking about that would be great. Aslo if this is bad could it cause a rough idle. Thank you all.
