Anyone with a 1997-98 Explorer 5.0 answer an under hood question for me?

@CDW6212R Anyone currently near their 1997 Explorer 5.0 that is stock under the hood. There is a curved rubber hose coming off of a port on the side of the engine oil fill tube. I need to figure out where it goes. I looked all over my half disassembled 1997 5.0 today and was unable to figure it out. Thanks for any info in advance!

That other end goes directly into the air intake tube

@Turdle. I thought it did. My brother just put on upper and lower Explorer manifold along with the throttle body from the Explorer on to his '88 mustang and couldn't find a place to hook it up to like it was on his Mustang throttle body. He found a cast place on the Explorer throttle body that would need opened up and a little piece of tube pressed into it to be able to hook to the hose hooked on to the fill tube tap. I believe that's what he needs to do. Thanks!

No, not good. Should be ahead ( upstream) of throttle body by a good foot or so. After throttle body would allow too much vacuum to it.

That is the " intake" to the pcv, connecting it to constant vacuum would ruin the ventilation function.

@Turdle The PCV is on the back of the engine and connects to a port on the bottom of the upper intake. If it is outside of the throttle plate is that ok or do as you are saying?

You want it outside the throttle plate yes, and we'll in front of it to catch vapors. Just my .02.
