A lot of things on NJT MCI's are different,I ran across 1 with a DDEC 1 engine that was straight 12 v with a air starter they did that because the DDEC 1 is 12 V only they have their own manuals and it changes with serial numbers, of the 1100 or so NJT Mci 9's you don't see many for some reason
NJT did some weird stuff like the Eagle was a 12V system they used a 24v air and heating system with a air starter then every wire was white in color with a tag you couldn't read.Gary Hatt the owner of this board has a NJT MCI 9 moose cabin also

I think you will find NJT MCI 9's are 10 to 15v on that valve I could be wrong but I have chased that problem on the NJT 9's before

That would be surprising, but maybe they did something different there just for NJT.

Normal MC9 schematic has 24v going through the 12v discharge and blower cut-in relay to rear stud 2 to feed front stud 30 and then terminals 1, 8, and 7 on the
coach heat relay. From terminal 1, it goes out through terminal 3 when relay is activated to front terminal 43 to AC j-box stud 7, and then to water valve.
The heat relay is activated by the mercury switch sensing unit in the tunnel closing and grounding the coil on the relay at terminal 2. 

The schematic says the water valve is normally open.

I like that setup one lapper. I'll be able to slip up, grab it and run, well maybe when I was younger. You're right,they are really quiet. I have a Honda EU3000is that I have for around the house if needed and it is almost as quiet.

Wet exhaust is usually black, sooty unburnt fuel.  Can come from excessive idling loading things up.  On the air box drains, the check valves that were mentioned are supposed to close with around 5 psi of positive pressure in the airbox, which happens around 1000 rpm.  That should mean that there would be no leakage there when running on the road, just when idling.  Like the exhaust the black stuff leaking out may be mostly unburnt sooty fuel.  There will only be oil in the airbox if the turbo seals, blower seals or or the oil rings on the piston are shot.

Good info. What's a good recommended 7kw diesel unit? I know Onan has the name but I truly don't want a ton of complexity nor maintenance...

Found out the hard way on my tractor tilling the ranch field. hose came off the overflow tank and was very hot engine. It leaked all over the fI pump right below it started a fire on the engine leaked into the weeds in the field started a fire. FD had to come in and put it out and saved my tractor. Darn it, lol  Shocked

Thanks for all the advice, I have gotten most of the oil leaks taken care of. Put the slobber hoses into a couple of bottles and I have ordered a kit that mounts under the engine and both slobber hoses run into it. Cost me 85 bucks, not bad. I also found a pin hole in a cooper line, I think it's lubrication for the alternator/generator.  The only leak left is coming from the exchaust side of the turbo. Oil is leaking out from the clamp that holds the exchaust together, dripping straight down on the valve cover on the left hand side. Is it normal for the exchaust to be wet at that point.

Wow, not me. Timely question as the clamp on my, thermostat side, hose broke and anti freeze blew all over the engine yesterday. I saw white smoke out my rear view mirror and started looking for a safe place to pull over. The low oil light started to go off and I pulled into the shoulder just as she shut down. Luckily the shut off was working as I only hit 200deg. When I looked inside is when I saw the antifreeze blown all over and realized what had happened. Bad situation but I thought it was going to be much worse. No sign of fire. I am changing all clamps and hoses!!
