The pcv valve on the 85s SE 2.5. My tube routing comes out of the throttle body and turns towards the valve cover and the pcv lays on it's side. This is correct?

That is correct.

It doesn't seem to me that the valve would work too proficiently on its side.

That is the design. I converted mine to use the 88 duke PCV valve, which is the more conventional vertical design in the valve cover.

The '87 Duke also has the PCV valve on the valve cover.

And get more oil suck thru PCV. Valve cover doesn't have shielding to stop that.

Old design give some space to prevent PCV sucking oil splash by valve rockers etc.

If I were to buy a new pcv, is it the rubber elbow with the pcv or just the pcv and I have to pull the valve and swap? Thanks Stacey
