I changed the PCV valve on our car while I had the cross brace out to
get at the brake booster, but the PCV valve end of the hose was rather
hard, and I'm not sure that it's sealing well to the new PCV valve. The
rubber hose is larger at the PCV valve end than at the end that goes to
the water-jacketed section of metal tube -- and has a 90-degree bend in
just a short length of hose -- so I'm not sure that sold-by-the-foot
hose will work: it probably will kink. Went to the Chrysler dealer today
to buy the genuine article, only to be told that they sell only the
complete assembly with two rubber sections and the water-jacketed metal
section for approx. $150!!

Any good suggestions for a way around this?
