First time poster here so bare with me. I have a 1985 ford F-150 Vin code on engine is N which means I have a 302 V8 Fuel injected, I am replacing exhaust gsakets and valve cover gaskets and had to remove upper intake manifold and found the 2 loose rubber hoses behind it not hooked up to anything. One hose looks like it goes to a fitting that runs into smog pump and to the exhaust and the other one goes to the back of engine could you please tell me what goes there, I will try and include pic.

thanks

That's the diverter valve, and it's melted because at least one of the check valves below it failed.

cool thank you, now how do I figure which one is bad the actual smog system hasn't been hooked up for years and I am in the process of trying to make the truck pass inspection so I want to try to get it all running again if need be to pass inspection.

There are only 2. Either remove them & look inside, or disconnect the 2 downward rubber hoses from the melted valve, start the engine, & check for exhaust blowing out. Regardless, I'd change them both - no sense in risking a new $50-200 diverter valve to save $15 on a 20-y.o. check valve.

There are a BUNCH of pics in those albums that apply to what you're doing, so click the PREV/NEXT links at the top of the page, or click the album name link to see others.
