My 01' 225 was suffering from a large vacuum leak. I found the leak and it looks to be from what I think was a check valve. Unfortunately I don't know much about that kind of valve and there's no part number that i can find to bring to the dealer.

Can someone help me with the part name, or a better description beyond "check valve" so I can at least point the parts guy in the right direction? Or can i simply just hit the local parts store and grab any generic valve?

The part is black and white. It was located on top of the engine by the air filter intake tube. It looks like the hose from it is connected to the top of the intake manifold.

In the picture the valve was where the silver tape is.

check this link, looks to me like you need part # 22A which includes a lot of other parts.

Thank you so much for that link! I have had zero luck finding a parts diagram like that. Exactly what I needed.
