"driven a few hundred miles since we had the oil changed and filters replaced"

Did you happen to look to see if the oil filter was still there? I have seen numerous times where people have lost their oil filters on the highway not long after oil changes.

Whatever you do, follow up and don't let this incident sour you on the coach. It may be something minor and just a bump in the road.

Agree with Pierce on reply 18,this may be an easy fix.

I put a call into the truck shop I use as per their willingness to work on the V6. should that be needed (hopefully not) I'll post up their reply.

Just a suggestion for the future. Call Coach-net and spend the $200 on a towing policy.

I will call! I have AAA and Progressive but both only cover a small fraction of the towing expense.

That depends on where I can find a mechanic.

With all the timber industry in that area you should be able to find a road man that is familiar with a 6V92.

Here is what the mechanic said:

Oil leak coming from unknown component. Seems to be oil pump or possible driving force for alternator. Leak is coming from seal connecting to intake manifold.

Can anyone identify the unknown component?
What is the difficulty level of the fix?
What should I reasonably expect to pay for a fix? and does it need to go to a shop or can a mobile mechanic fix?

The current shop said they could fix it but don't want to because it will take months.

Thanks!

Someone with your engine will soon answer,but if the "shop" can actually fix your problem but somehow will take "months" I would
run like hell and find another place.

1) You're talking to the wrong guy. DD 6V engines are not rare or exotic, the guy you want can tell you what he's seeing.
2) Pierce?
3) Ewwww. That's difficult. Unskilled labor can do much damage if heavy handed. Or a patient guy with a parts manual will get the job done eventually.
4) Skip.
5) The current shop knows nothing about Detroit Diesels and doesn't want to learn working in the back of an RV.

Not sure on Detroit's but it looks like a power steering pump. See what Bigdog comes up with for a reputable shop, and there's also JD Truck repair in Pasco, near the river.

Presuming the 6v92 shut down because of low oil, I'd add oil and drive it if I could.

Didn't get a call back from the shop. It's just a few miles away, So I'll go over in the AM and ask and show them that photo.

Shop labor at mountain-hi is $135.

Appears to be a leak from the tube that feeds your blower.
Ours cracked, leaked quite a bit (dinner plate size when we'd park).
Completely broken or gone maybe?

Looking down at the photo, this is the back (toward the front of the coach) of the engine with the alternator with it's two V belts top right easily seen. A little below that is the power steering pump, internally driven and below that and a little to the right is the air compressor with the fins, also internally driven. Also visible is the little cap on the air governor where the air pressure for the brakes may be adjusted. There is a small very short hose that can leak. Ours did but not a huge amount and not enough to lose a lot of oil. That area should be cleaned and then checked for a leak. Ours does not use any oil to speak of and only burned 2.5 quarts in a coast to coast and back trip but some do. You do have to check the dip stick frequently as well as the other tanks and air cleaner gauge. Since the owner has only now learned about checking the oil, it may have gotten low enough that the DDEC started the shut down procedure. If a gallon or so of oil can be added and the engine starts, it then should be checked for leaks and if none are serious, it may be driven home with the dip stick/oil level frequently checked. To the owner, your Detroit needs a special low ash oil, best with Delo 100 #40 (not 400) or Shell Rotella #40. The capacity is 5.5 U.S. gallons with filter. Using any other and especially a multi grade is asking for engine damage, with stuck rings high oil consumption and poor starting the result. When checking ANY diesel's oil level, the dip stick should be smelled for signs that diesel is getting into the crankcase from a fuel pump or injector leak. This dilutes the oil and will also cause premature wear. Unless an owner has a unlimited credit card or does not care, it's very important to know where all the critical fluid levels are located so they can be checked and also the belt condition. Spare belts, filters, especially fuel, oil, coolant should be carried.. Foretravels have been parked in a garage where the coolant level went below the sensor and the coach would not start. Since the coaches engine compartment was against the back of the garage, coolant could not be easily added. As I remember a very helpful member traveled to the coach and helped get it started.

If I remember in the morning, I will take a photo of the potential leak spot and post it.

Perhaps a faulty oil filter. I would strongly advise you to go over it with your coach and, as previously suggested, check the oil dipstick to see if it is low. It will most likely not display anything. If you try to sell it as is, you'll get pennies on the dollar.

I would do what Dakota Slim said. Once the oil is full and if oil isn't pouring out it can
be driven. Looking at the picture I can't see a big oil leak there is looks to me like there
is a tiny oil leak and it took along awhile to accumulate. Talk to my friend who has rebuilt
lots of Detroit's and he said to make sure the crankcase breather tube is clear as if they
get plugged the pressure in the crankcase will blow all the oil out.

My shop said they have no issue with working on a DDtwo stroke. But as they are the main shop that the local farmers and wineries use for their equipment. They are always 2-3 weeks out.

My shop said to give North West equipment a call. They just opened a new shop just outside of Pasco in Burbank, Wa.

Thank you for taking the time to reach out to your shop!

NW Equipment was actually my first call while on the side of the road and they said they couldn't service the coach. I think I'm going to have it towed to Fat Boys fleet services.

Best of luck and let's all pray it's something easy and cheap to fix. Be sure and update us when the fault is found.

I think you may find the leak is at that pump or to do with the Blower for your motor which is the big squarish looking intake behind that pump. Blowers do need new seals from time to time. What is the mileage on your engine? As previously mentioned only straight weight 40 grade motor oil. Less than 1% ash content. Rotella 40 or Delo 100 40 but not Delo 400 40 don't mix them up. Also since it was ran so low on oil and if the mileage is up around 100,000 I would be tempted to have them pull the oil pan off and inspect the rod and main bearings just for peace of mind. You can thank that DDEC computer on a mechanical 6V you would probably have a large paper weight by now. I would inspect all oil lines for integrity and strength. You need a good two stroke guy.

Update: The supercharger has to be taken off to find the leak. I'm told 10-20 hours of work and the leak is significant.

Re: No Oil Pressure in Need of Mechanic

Reply #49 – June 01, 2022, 04:06:09 pm

Seems like 10 minutes would find the leak on our Detroit or any other engine. I mean, how many places can a leak be coming from? Cheap gasket on the back of the PS pump or hoses, air compressor gaskets, etc, etc? Sounds as if your shop has found a golden goose aka the danger of owning an RV and taking it to a repair facility. $30,000 can disappear in a hurry as "they can't guarantee the repair without replacing the reflex valve, optimizer, rotary valves, etc"

If the leak is significant, where is it coming from? What does significant mean???
