Truck runs about the same, no worse, maybe a little better actually, but I still get the occasional 'dead miss' sitting at a light.

Been racking my brain try to figure out what I might have done. I was a little distracted and rushing because of approaching rain when I swapped everything out.

Then, I thought of it.

While routing the pass. side plug wires, I noticed the hose for the PCV was barely on (at the manifold), so, I just pushed it on and went about my business.

Looked at the hose tonite. Yeah, its as hard as you'd expect 22 year old hose to be, BUT, the underside is missing a chunk/section as long as the fitting coming out of the manifold. Looking down on the hose, you can't see it. With the hose barely on, this left the manifold port open mostly sucking just air. When I shoved it on, it was far enough that it was drawing from the PCV again.

The missing piece is not laying down in the recesses of the manifold. Deliberate action by someone?

When I posted the video of my truck in another thread, someone mentioned the idle sounded a little high. Hmmmmm.

I haven't been able to swap PCV valves because the grommet is rock hard.

So, with the hose hooked up, could it be sucking oil now?
