Crossing Streams in PSDs
Some one told me I needed to be careful about crossing streams, etc, with a diesel. Is this true? What do I need to be looking out for? Something about "breather tubes"???
Thanks for the help!

And Hard. I was on a dirt bike one time crossing a stream when the back tire slipped sideways on some moss. The bike went sideways down into the water and when it sucked a little in, it sounded like it had been hit with a sledge hammer. I never did bother rebuilding it, good thing for disposable Honda's

You need to locate the air intake up higher than the stream you are crossing keep in mind that if the body of the truck gets into the water the water level in front of the truck will be higher than the stream level.
This is more important with dsl vs. gas because the dsl is compression ignited. A gas motor will usaully stop running before it gets a good dose of water down the intake because the spark plugs will get damp first.
I use to cross river headlight deep with my 91 F-250 (4" lift with 36" military humvee tires) with the stock breather with the air intake hose removed, and never any trouble.
Keep in mind with a dsl that just 1 measuring cup full of water down the intake will trash the motor.
My had no turbo either. So I don't know what the consequences of fill the intercooler and turbo with water would be.

I don't know if there are any breather ports down low on the PSD. Nor am I sure about the impact of soaking the lower alternator.
Yes, the obvious things to avoid are getting in so deep that you suck air into the intake, also good to note that drivers don't do well submerged for long periods of time.
I've used my X in flash flood situations. Two feet of fast moving water can make things very interesting for you.

You will also want to keep in mind that if you were to be crossing water deep enough to get into the air intake, then the factory vent line for the differentials, transfer cas, and most likley the transmission are going to be underwater.
It is a good idea to get the proper size line and run all the vents lines up higher than any water you indend to cross.
