I have to replace the PCV hose (the hose from valve cover to the PCV valve) as the old hose is toast. This is on a '96 Caravan with 3.3 V6. I have the hose but the area to work in is behind the plenum so I guess I am working in the dark. Any tips, should I remove the wiper motor tub, all responses gratefully accepted.

 

I would remove the wiper tub before I'd remove the plenum. At first glance the plenum appears easy. But there are a bunch of support brackets on the rear end of it and they are a B___ch to get at. Change spark plugs on the rear bank while you have the tub off.

 

Thanks for the response. I did the plugs and wires last year and took the tub out for that repair, but, I never thought about the PCV having a hose off of the rear valve cover (I was familiar with the clean air hose off of front valve cover) and when I discovered the hidden hose that was fried, it amazed me, plus they hid it in an almost impossible spot to get at ( and I thought my 1988 BMW 750il was bad). I guess a tub removal is in order.

 

The secret is not the tub, but the coil pack, once that is off you can touch the end of the hose at it enters the valve cover.
