Slobber tube - cheap fix for blowby

Slobber tube - cheap fix for blowby
Greg, IMO Shane's plan is a good one. I had the exact same home-built
PVC catch system on my 83PT. as Shane pointed out, remember to vent
the tube so there's no back pressure on the scavenging effect. With
the PVC tube horizontally mounted under the trailer hitch assembly,
the slobber tubes still hang down vertically. They are just routed
somewhat backwards, just as they swing back in the wind when you are
driving down the road. Worked good for me also. It wasn't cleaning
the toad windshield as much as it was the burning smell of the oil
that got into the toad radiator and then burned off when the radiator
heated up.
