The Stovebolt Site Forums The Shop Area Driveline Caramel milkshake??

The stuff I drained wasn't near as light brown with bubbles as was the stuff I had on my finger thru the level checking hole Friday. I drained it (no, it wouldn't drain through the bottom bolt holes) by taking the cover off, used some diesel in a spray bottle to wash down what I could reach, let it drain for a few hours, washed it with diesel again and let it drain overnight. This morning I put the cover back on, filled it with diesel, jacked the back wheels off the ground, started the engine, put it in high gear with the idle set high and let it run for 20 minutes or so. Shut it off, pulled the cover, drained the diesel and let it dry out for 6 hours with a fan aimed at it. Put it back with a new gasket and filled it with GL-5. It took almost a quart.

I was wrong about the vent. It is on the cast center housing about 4" above the horizontal centerline of the rear axle. Being a flatbed, there is lots of room under the bed for water to splash around from driving through puddles, but I really can't think of a time when I was in water over an inch or two deep. Certainly not deep enough to submerge the vent.
