I've gone through a couple different PCV elbows - the one from the 4-speed intake manifold nipple to the PCV valve is what I'm referring to... As soon as they get a little fuel or oil on them they swell and don't fit any longer. I haven't seen an NOS one for a long time, and I haven't found a repro that works well. Are there any good suppliers of this part or any substitutions that anyone is using successfully?
Bob---I would reach out to Jim Michaels from Classic Olds in Clemmons, NC and he can help you. He just sold me mine for the resto I completed and it works great on my stock W-30 intake. Tell him Dave from CO sent you his way.

Each one of those vendors seems to use the same supplier, as I've gone through several of them. It seriously just takes a few days before the snug fit isn't anymore, and within a week you have oil blowing out around the edges onto your manifold. I've found an NOS one for my final restoration use, but for now, I'm curious if anyone has found something that works well for them, or if everyone is just letting them leak....!
My tractor has a similar ish 90 degree hose for a trans cooler. Its super common for them them to blow out or leak after a few short years of use.
there is a retrofit kit to replace the 90* parts w steel tube. I tried some other than OEM hose there and it was in poor shape in less time.
the point of my long winded tangental reply is the 90* tractor hose ( made for hot oil) if a correct fit is likely a better quality hose than the repro part your using.
