slobber bottles
« on: April 10, 2021, 10:16:04 AM »
was having leaks on the ground, 1st assumed blowby--turns out the manual oil pressure gauge was seeping oil thru the glass. Fixed that.
I would still like to hang some slobber bottles back there--Is this an actual available part? or just something you jerry rig? Suggestions?
Thanks

plastic jars? That was my concern if they would melt.

PVC pipe works too. Put vents and drains in them. After changing my engine it isn't as big of a priority as it was before.

air box drain ck valves on side of your engine( both )  are meant to close about 700 rpm and direct any moisture or oil etc thru your engine. Designed to be open at idle. That said they gum up and stay open all time or fail and it stays open all the time letting the mixture fog up back of your bus (spots etc) new ones are cheap. keeps toad rust proof! take apart and clean or replace.

After I rebuilt both my slobber valves (both were stuck open), I added some 3/8" tube from each one to a 3 qt Costco juice bottle that sits inside the rear bumper, with short lengths of clear tube going into the bottle so I can easily see how much is actually slobbering, and I can check that the valves are closing correctly.   Easy!

Find a bus junk yard with old transit buses just about all of those had the Walker catch can ,most older 71 series didn't have the check valves on the air box drain those came later from Detroit attempting to please California

Can the older 71 series be retrofitted with the check valves? Would it help reduce spotting on the back of the bus if they could be?
