[305 TPI] Drivers side PCV valve tubing replacement?
Hi all,
the tube that connects the pcv valve to the plenum on my engine cracked and I need a replacement. It seems pre-bent so is there a part number associated with this hose? Or do I just replace it with a generic type of hose (if so, what type? Seems to be multi-layered)

The driver side should be fine with just a standard vacuum or fuel hose. The passenger side is the weird curved one on my cars.

The valve cover configuration changed on the 90+ speed density engines. Oil fill at front of valve cover and PCV at rear of valve cover. So just a short piece of hose will work.
89- Oil fill at rear of valve cover and PCV at front of valve cover. Has a longer molded to shape hose.
