It's been awhile...work and kids...you know the deal. Anyways, I replaced my valve cover and gasket over the weekend. What a fun job that was. I removed the air cleaner housing to find that the thing was moldy on the inside with a ton of rust. The PCV filter definitely needs to be changed, which I have noted. The other things located in the housing needs to be replaced...they look like hell. I don't know what they are though and can't find any documentation that states it either. I have a Hayne's manual, but I can only pick out the PCV Filter, and a senser, that sits on the bottom (Which I have no clue what it is for). On the side of the housing, there is a round disc with two vaccuum tube connection points, also, there is a round disc that has a metal face (sits on the inside of the housing) and an electrical plug (sits on the outside). My question is what are all the things that go in the housing and what are they for? Can I obtain a replacement part for each? I had the housing sandblasted and primered. Now I have to paint the housing. Another thing that puzzled me...the PO put a screw in the top of the housing to hold open the trap door/flap on the inside. I haven't the faintest idea why...could anyone clue me in? I bet this is why it was rusted out and had white stuff growing in it...
As always, Thanks!
If it's that important to do on a Friday, it can wait until Monday...
