Do a quick check of the Turbo. See if it is pushing oil? If it runs well, just burns oil, a seal in the Turbo could be your problem. That is a high rate of oil consumption, or loss? You will be able to see it. Does it Smoke?

Here is a photo of mine. Yours is a newer design? Mine is a 1987 model top is a bunk. A bit tight for me up there but manageable.

Mine didn't come with the propane bottle either.

Okay, here are some engine bay pictures and dumb observations / questions:

Small labels in the image above are for:
1. This hose goes nowhere, and aligns nicely to where I saw large drip / small puddle forming after a highway stretch at 65mph. What the heck is this hose, and where is it supposed to go?

2. This is not connected. Is it a turbo-timer or some other pump that is supposed to run after the engine is shut-off?

3. The pressure cap has a hose that goes nowhere. You can see it terminate middle-left of the photo. Normally it tucks over a bit and just hangs down. Shouldn't there be an overflow tank somewhere, or did they not bother with it because the engine-bay is pretty full?

Additionally, this little guy isn't connected to anything (bottom middle of 1st pic, middle of 2nd pic). Where is it supposed to go, or just a test-lead?

And finally, this line seems to be a dead-end. I wonder if this is my fuel-feed for the diesel heater Exclamation

# 1 is your return line from the crankcase breather. That should go either in a catch can or back in the block (here's an image of my IDI diesel before installing , you can see the hose going from the puck down into the block: https://www.flickr.com/photos/srmpf/9113575120/in/set-72157626192344066) EDIT: looking closer at your pictures it looks more like the other hose going from the puck to the intake.

#2 is a electric pump for the coolant system. some european vanagon diesels came with it. connect it to your alternator via a relay so that it runs when the engine is on.

#3 should go to an overflow tank. the idea is that the coolant flows in the overflow tank when hot (expand) and sucks back the coolant when it cools down so that you don't have any air in the system.

#4 if don't have any idea

#5 i would check where it starts - if it's really for your diesel heater you should double check if it doesn't squirt diesel when you want heat Smile

oh and congratulations - that syncro looks awesome!

#2 is an aux water pump that will run AFTER the engine is shut off to help cool things down. Only the turbo diesels came with these along with a fan and ducting to cool the turbo after the engine is shut down. There is a relay and wiring behind the drivers taillight.(and the fan) No idea if the conversion to TDi kept the relays that make this system work.

If the relays and fan have been stripped from the van you may want to eliminate the pump and excess hoses.

Another note - despite new harness+glowplugs, the glow-plug light is on dimly all the time. Ideas?

Any further thoughts on the hose routing / unconnects above?

number one is the breather and on a standard set up joins to the air intake to turbo (hard plastic pipe)

number two is the aux water pump, only comes on with ignition off and very high coolant temp

number three, pressure cap hose should run to a top up tank situated behind the numberplate flap (as per petrol engines)

loose wire, don't know

fuel hoses, i can't quite see where they all cross over. but the two spigots facing the back of van on the filter are the fuel flow and return to pump. It looks like you have something t'd into one of these with a little filter? if so, yes that could be the supply for a heater.

#1 is the crank breather and the typical connection would be in the intake between the air filter and the turbo compressor inlet. Take great care with connecting it, though. If your engine has excessive oil in the crank case vent, it can cause a runaway situation where the engine runs on its own crankcase oil. When that occurs, the engine will run on its own at FULL POWER. The ignition key will not turn it off and if the clutch is depressed or the trans placed in neutral it will rev uncontrollably with internal damage very likely. In that situation, the thing to do is to keep it in gear and stomp on the brake to drop the rpms until it stops running away or stalls.

I had that occur on one engine of mine and despite keeping a clear head and reacting properly it was quite frightening to have the vehicle take off on its own at full power. I was jittery for the rest of the day.

I don't quite understand why there's a pre-filter fitted to either the outflow or return side of the main filter, since it has fairly large mesh meant to nab large chunks of rust and algae being expelled directly from the tank.

The crank vent will always blow some oil. The real question is how much is coming out of yours. You can run it into a catch can and place a crank vent filter from a V8 on the can so that you can see how much. The engine I had that ran away was running an absurd amount of oil through the crank vent. I'm not exactly sure how much as I didn't drive it much before it ran away and immediately took it out of service. It was definitely more than 1 qt in 500 miles. My concern in posting was the possibility that the engine ran started to run away on the previous owner and that they disconnected the crank vent in order to prevent the issue from recurring.

Can you get pics up of the turbo and oil return line?

the block will cool down quicker with the pump running as it circulates the water(removing heat). The water is likely to boil if just left sitting in a very hot block

Hello Brian
How is the rig? Do you have any updates? I got mine and got busy doing other stuff. I did use it a few times but have not built it out much. I am a bit bummed with the cabinets. The middle cabinet requires the seat to be in the bed position to access its' contents. Other then bedding in there is a pain. How are you liking yours?
