On our trip across country already at Hover Dam. Anyway I've developed an oil leak that is getting worse by the day. It's a t-drive setup. The oil seems to be running along the top of the intake under blower between head and blower. (it's like a half inch channel there) It's not the valve cover leaking. looked and looked and can't find the source. Any idea's? Thanks
The blower supply oil line is probably the culprit
"The blower supply oil line is probably the culprit " Where is it located?
On the back of the engine a 1/4 in tube with a nut and special o-ring it supplies the blower with oil from the engine, access is from the inside of the bus through a hatch,if you have a tack drive on the blower the holding strap could have broken also
good luck
Thanks, I'll check to see if the guy that did the conversion left a way to get at it

In a pinch, I think (iirc) I have "made" that seal ring from neoprene 1/4 inch id hose...

I pulled it apart and replaced the o ring and that solved it.
Thanks all. I still haven't found it even tried putting my camera back there and snapped several pics but, couldn't find a 1/4 inch line. Did find a hose coming of the side of the head going somewhere but its Luke 3/4. And something kids like a solenoid valve (maybe its the tach drive) couldn't tell if oil was coming from there. Anyway getting worse so, still looking
You are going to need access from top side to see and replace the o-ring lol a simple job once you gain access
I just can not believe some one has oil leak on a detroit diesel.
uncle ned
PS its monday morning on a tuesday
There is a 4"rubber boot on the back end of the blower. Along side and on top of the boot there is a short steel oil line parallel to the boot.
(Right Clifford 😀)

I found it. The nut was loose so I, tightened it and let motor idle for awhile and no leak but, still getting the oil mess. maybe under load it is leaking. Going to find a Detroit shop and see it they have the o-ring. Can it be leaking under the blower?
This is a pretty simple fix. No need to find a Detroit shop. Pull the pipe off, take it apart and go to NAPA and get an O ring.

Thought it was some special o-ring?
OK, replaced that o-ring but was not the problem and now the problem is much worse. Losing over a gal. In 50 miles. In the middle of nowhere in Three Forks, MT .. As best I can tell it's coming out under the front of the blower it takes some doing to even see under there. Any more ideas please?

If its got worse by doing the O ring, did you do something wrong installing it? There is a truck stop there and a Flying J to the east. You sure dont want to venture far from there if you are unsure. Theres not much else and if you are heading west you have a big climb coming up.
sorry about the big picture...but i was hoping to make it clearer things you may not be able to see.
there are only a few places oil can leak....
the small tube
the large hose
the blower end covers
the governor area
govenor rack control rods front to each head small short hoses
the valve covers
the end plate between the block and gear case
a gallon of oil makes a huge mess. do you have a huge mess ? the whole back end of your bus black ?
Back of bus and toad black..... No it got worse before I did the o-ring. Not leaking there. Looks like maybe the front blower cover or the back of the governor box very hard to get at. There is a Detroit dealer in Billings but it's 150 miles away and I'm down to my last gal. Of Dello 100. In a pinch is there any other oil that I can buy at a truck stop that won't kill the motor?

Adding 15w40 will not kill your motor.
I worked for a Chevron jobber or 20 years.. I know a lot of owners who ran Delo 400 for ever without any problems.
I would do it with out even batting an eye.

Thanks! I called Rons earlier but, lady said he was not available tell after 11pm. Tonight and would call me back so, will wait tell morning and see. I don't have enough tools with me and have never messed with things like the governor box and if it could be messed up know I, could do it....lol
It does take a special o-ring 4 bucks from DD you losing that much oil it is a pressure leak not a return leak.install the correct seal and check the coupling you are not going to lose that much oil on the return side of the blower.
Those engines have 2 different styles of supply line and not knowing if you have the old style makes it hard to help it will pour if you installed a o-ring in a newer style tube. If you are on F/B I can show you how to fix that leak but photos here for me is impossible to post
The blower to block gasket ("blower mounting gasket") seals the return oil holes to the block. I have changed several that have gotten hard and was the cause of an oil leak.
--Geoff
They will leak sometimes at the blower gasket but he is not going to lose a gal of oil every 50 mile from a gravity return and he said he made it worse by changing the o-ring.The rear mounted tach drives are famous for the strap or set screw breaking and causing a major leak too
Thanks folks. At the diesel shop mech. Says it's coming out close to a water pipe that's in the front of the blower in the center near the bottom. Keep u posted
No luck mechanic said he couldn't fix it and would have to get it to Detroit shop in Billings. Said it could be a bolt behind that water neck in the blower front cover that backed out or something. Anyway he thought the blower might have to come off
There is another guy in Billing that is a good 2 stroke shop but I for got his name are you out there Andy Wright ? help this guy stay away from Interstate
Thanks. Found out his name its Jerry Olson Big Sky Diesel. Hes booked up through next week
If you go to Billings don't take it to the Interstate shop right by I-90, take it to the one up in the Heights on hiway 87. Hopefully Larry hasn't retired yet. :)
Do know the name of the shop?
There are several 2 stroke shops in Miles City Mt if I can find my book I will post some numbers one is mobile he will come to you.Check for Rimrock Stages if they still have the shop open in Billings they will work on your bus
Rimrock out of biz. Made it to a Walmart about a mile from interstate diesel the one not on 90. Hopefully I'll find someplace else. It took 5 gal. Of oil from Three forks to here 180 miles

But you made it... ;D
Scot Becker is the service manager there. That is where i had my engine rebuilt last summer, Chris and Cherie of Technomadia had theirs done there the year before. Say hi to them for me, we will be back there in Sept. to have them check everything before my warranty expires.
OK Ed, will do.
Don Fairchild is 200 miles from you I can contact him and see if he will fix it for you on his day off Sunday
Please my number is 540-937-0538 thanks
Lee,check your E mail
Got it. Thanks Clifford! He said I was at at good shop to get it fixed so, I'll camp at Walmart tell they open Monday. Oh, he thinks it blew the gasket under the blower
Bummer I hate those high dollar leaks,usually when that gasket blows they go down on power and the black smokes rolls you made no mention of being down on power
No loss of power runs like there's no tomorrow. Just pouring out oil. Hopefully I'll know the culprit tomorrow
Well left Walmart this morning and drove up to Interstate shop and parked. About 2pm a truck came in for after hours emergency work. I talked to the mechanic and he said he'd have Larry come in at 7am and get started on me. Maybe they'll get it fixed by the end of the day
Tell Larry that so far my engine is running great! ;D
If it ends up that you need to stay there for a couple of days there is a motel right next door. They were booked up for several weeks when we first got there so we ended up down in town at the Dude Rancher Hotel. Prices were about the same for both and we never looked at the rooms in the other place, but the Dude Rancher was fairly nice and i have a feeling it was better than the other one. It is 3 & 1/2 miles from the shop. Just go down the hill, stay in the right lane and go to the right along the base of the hill until you get to the Library which is on the corner on your left. You want to be in the left lane and turn left just as you get to that corner. In the middle of the block you turn into the bank parking lot and the entrance to hotel is just in front of you.....lot of one way streets down in town so pay attention if you go there.
Alright Ed, message delivered. He remembers you. He said it's the blower gasket near the oil feed or return ports and I would have had no loss of power because of it. Anyway tearing it down now
He's got the blower off and it was the gasket at the front of the blower right at an oil hole. Cleaning stuff now said he may have it done tonight
You were lucky it didn't blow to inside,I hate that leak a $10.00 gasket cost you 1000+ bucks to replace
I'm sure it's going to be costly. He said my blower had a little play in the shaft but will be ok
Thats what I said it was.
--Geoff
Yep Geoff. >:(Tried to upload a picture from my phone to here but can't make it work. Anyway, he has the blower back on and will finish tomorrow. 8 hrs. So far
Hope they got you out today's that is not a fun place to spend much time with the meter running

Nope they just flat rate to the manufacture for warranty work which is almost a 1/3 of what the public pays so says Bill at WW Williams

JeezPeez...
So I guess the guy doing the work today gets peanuts ;D
Willaims pays 20 to 28 bucks a hr for a mechanic I never could understand why bus people don't use www.truckdown.com (http://www.truckdown.com) .I used it for years and knew what the rate was before I found a shop.
It really ticks you off when they charge 95 bucks hourly rate for a seated bus then want 125 to 140 bucks a hour to work on a bus tagged as a RV,I find the FreightLiner dealers the worst and they manufacture RV chassis.
I cannot figure it out the shop guy at Vegas FreightLiner said it was because it took longer what the hell you are paying by the hour so it takes a extra hr no big deal @ 95 bucks not 8 hrs at 140 bucks
Well folks here's my sad story. Yea they got Done today Well, not exactly.... my intake air hose had a small split in it and they couldn't source the correct size locally 5 1/2 inch so the got a six inch and made adapters to make it work. Oh did I mention my bill was $2787 after they were kind enough to cut the labor from $135 a hour to $120. My tail hurts! To add insult to injury after leaving the shop going east bound on 90 I realized I wasn't making enough power to pull a wet string out of a chickens a$$. After 22 miles turned around and now back a IState waiting for them to open in the morning. Seems that air tube they made up kinked near the turbo and the kink also interferes with the air throttle and now it's leaking air and not fully opening..... so, the fun continues

how much of that was parts ?
Bummer,I was hoping for a smaller bill for you, I don't say much about Interstate some people like Interstate.
They got me in ND $8100.00 for a head gasket and 1 liner kit on a 8v92 the parts were less than a $800.00
Yea never liked dealing with dealers. The labor alone was $2280. I'd say Your $8100 bill was an even bigger bath then I just got. OUCH!

how do you get 2280$...a 10 hour day is 1200$...
Are you saying they paid 2 people....
back in my days at a DD dealer, a complete rebuild was 46-48 hours...that included hot tank, steam, gasket scraping pressure test the heads, and dyno...
the only hourly charge outs were for field work.
Billed 19 hrs. @ $120 per
Quote from: skytrends on June 09, 2015, 10:02:11 PM

Sounds like they charged you flat rate not hourly.
Wes
I don't doubt the 19 hrs in a bus there is more too it than just removing the blower and replacing a gasket.I was figuring 10 hrs but I wasn't there to see what all had to be removed but it sounds like a lot ? what model and make is the bus
It's a 63 Flexible new look city bus. 6v92 Silver with blower and turbo. Plenty of room to get blower off and never even needed to use the inside accsess panel in the back. It's a T-Drive
How did you reach $500.00 in parts that is a lot
Wife's put the bill somewhere but, they charged me $95 something for the gasket set plus $120 something for oil plus filter and then $80 something for the air intake hose they used plus I can't remember how much for the adapters to make it work. By the way that made upper intake hose is the source of my low power problem cause it kinked right in front of the turbo and also was hitting the throttle lever stopping it about half open. They are redoing that now
Finally all is back to normal. Larry is a good mechanic but, Interstate not on my favorites list. Tried to charge me another $379 dollars for making up another intake air pipe. I told them I already paid to much and they backed off and just dropped it down to parts so, $64 extra was all. I'm good with that cause I know have a custom made stainless air pipe with very short rubber on each end that looks good and will last a long time
If it weren't for bad luck now the fan miter box started leaking and tried to sieze up. Burnt both belts tell the broke. I can turn it by hand with the fan blades so going to take the side cover off that appears to be leaking and make a gasket put it back together, fill it with 90 wt. And pray
Dang, good luck

Well, we all enjoy them until something like this hits you in the butt. Everything on all of them seems to be like Gold.
Good luck Bubba and hope it quits giving you fits and starts paying you back with enjoyment.
What the heck is the deal with these shops trying to charge every time you go in even tho it is for a problem they should have fixed the first time ???I had this problem with Clark Power Systems .Started with a field guy in a service truck. Finally wound up having to take the unit 150 miles away to their main shop at my expense .To their credit ,they fixed it there but this was three times to their shop .I was charged all three times I took it back and to make a long story short I wound up paying $4500.00 for a 20 dollar gasket and a gal of Transend.They did agree to give me credit for a tcm that was installed on the first call provided I would let them take the unit out that they installed to start with and put my "old "unit back in.Well they did not give me the old unit back (which I should have insisted on)so I had no way of knowing whether the unit they but back was the same unit that they took out.I mean they had screwed with this thing a year and I couldn't believe that they still had my old unit just laying around to where they could get their hands on it that easy,and I couldn't come up with a serial number for my old one.
Sounds like a place to avoid
Next time some one is in the Three Forks Montana area and needs help look me up. I'm about 15 miles North of I 90 just out side there. Been tinkering on the diesels for a few years, about 30 of them. I have a shop with most tools you need to work on most diesels, Buy the parts and a STEAK or 2 for dinner and we'll get ur back on the road.
This is good to know! :)
