Air filter box, where the box connects to the separator on both sides has no seal. I took it apart to get to element, and found globs and globs of black silicone that looks like PO used to seal it up.
Taking it apart, a lot of the sealant came off, and I'm not sure if there is a factory rubber seal or not in the mess of goo.
Is there a factory seal that can be replaced? Or should I just glob it up with silicone every time I get to the air filter element?
