Could be that your blend door is broken and not moving all the way over causing more backpressure on the fan. OR... It could just the change in sound of the ductwork used for Cold vs. Hot, and not really the fan slowing down. Just taking educated guesses though.
Both good ideas, where is this 'door', is it the one in the passenger side footwell? Any way to test?
And here you can see the original piece of the intake hose that has the 3/4" CCV inlet hose attached. I just used a piece of 4" exhaust tube and cut it to length to replace it.

I then flipped the CCV 180 degrees, so that the vent pointed toward the rear. I ran a piece of 3/4" hose from the CCV in a loop upwards (to allow condensate to drain back into motor) then down the frame rail to the back of the van. I will add an oil catch can when I find one I like, but for now smell vapors are minimized and no more motor gunk into the turbo!
I was repairing a fuel leak on mine yesterday (fuel restriction switch) and noticed a good bit of gunk built up in my intake as well, wasnt sure if this was normal and was a bit concerned. especially after starting it and letting it run for a min while checking to make sure my fuel leak was fixed. The CCV almost immediatly after start up started pumping a decent bit of smoke, enough to see anyway....Im guessing this is normal?
Got the front painted up just before last weeks snow 'storm'. I snapped a few not-so-good pictures.

Also, as I said before I replaced the heater motor resistor, the battery under the van and most importantly, the STARTER.
I have had many 7.3l's in the past, and unless you have good batteries, good glow plugs, good glow plug relay AND a good starter, you have no shot at making it through the winter without constantly plugging the beast in.
My starter 'worked', but was very, very sluggish, even after the new battery. I knew ski season was here so I bit the bullet on a new motorcraft unit, and it now turns over so fast it almost screams! :sombrero: Cold start issues are a thing of the past!
Now the fun is to figure out how I can isolate the house battery, yet charge it and the van batteries with the converter and/or solar. Oh, and make sure I hook up my INverter correctly so that I still have 120 power when I am not plugged in!
That is a lot of work for such a small part! Good on you to figure it out. For your batteries/charging system have a look at these guys:

I got from them a 15 amps 24v-12v converter that alloys me to charge my house battery while insulating the starting batteries (product# E49053). Your application is slightly different but they should have something for you. I've tried a few other system in the past which never performed as good as these units.
Cheers
Mr. D
Nice bumper btw!
Hey Scoutkid,
You are a nut case and I mean that in the nicest possible way!
I just read your whole report and am impressed with your work and especially your seeming ability to work 24-7!
My project has been a 2000 E350 7.3 EB. Over the last 3-4 years I built a marine quality, westfail-ya style interior layout and had sports mobile install their lifting top.
I used one of these guys solid state isolators with a pr. of 6v golf cart batteries mounted just aft of the rear axle:
http://www.hellroaring.com/ Really helpful guys from montana.... Its been 3 yrs and going strong. Good bang for the buck with the golf cart batteries.
My next step is 4x4 conversion. I have a quote going with Chris (thanks Chris!) and have been searching southern Idaho for a front axle and xfer case.
I'm curious if you overhauled your axles before install? How many miles were on them? Does anybody know how long the fronts can be expected to last before requiring bearings etc? I've found a good deal on a Dana 60 front but its got 150Kmi on it. If its going to need outer bearings (unit bearings) these are spendy and a good deal is not such a good deal anymore.....
Also - why did you replace your rear axle? Was it not a full floater?
Thanks and good luck with the rest of your amazing project!

Solar charge controllers make fine battery isolators. Charge the house batteries when the engine is running, won't backfeed, limit current so you can downsize your interconnect wires (still need welding cables if you want to self-jump), smart charge, and isolate so you can have multiple charging methods running at the same time.
