Is there anyone out there that would be interested in some help via email to enhance the performance of their GM Diesel engines for tractor pulling? I am a retired diesel mechanic with 46 years experience working on Gm (Detroit Diesels) Included in this experience was 23 years of teaching Diesel Mechanics at our local technical college. I also spent 14 years in Super-Semi truck pulling. Our unit won the Grand Nationals two times during that period. I built up an 8V-92 Detroit engine to over 2000 dyno hp.I would be very happy to help someone who wants to pull an Oliver with a GM Diesel.Done correctly there is nothing out there that could outpull them. There is a lot of bad information out there about these engines. Anyone interested please feel free to contact me via email.You could field a consistant winner. Jim Bute

Jim, We have an 8V-92 engine in our semi-tractor. We are suspecting a broken fuel injector but have little experience with internal repairs on the Detroits. Do you know of a good service/overhaul manual? Thanks! Cary

I am looking at a Prevost 1994 Motor Home and one Detroit shop told me the 8v92 engines are a mess .. this engine has 116.000 miles and the oil analysis comes back excellent

I am asking for a problem with the 8V92?

Thanks

Dick Scottsdale AZ

Hi there Jim,

My brother and I are currently putting back heads on my dads ford dump truck. The manual says the head bolt torque is 110ftlbs but also mentions a torque and turn method. It says to give the head bolts an additional 1/4 turn. I usually work on small cars and trucks that don't utilize diesel engines. Is this additional turn necessary and if so why is it done this way. Thanks for any help you can offer. Can you please email me with your answer at [email protected] Thanks again.

I have a 6v92 Silver TA In a Ford 9000 Dump Truck. It has been just rebuilt and has Re.man blower and ijectors. I would like to know if i can get more power and better fuel economy? Or at least better MPG. It seems to smoke more than others.

Good to see another fellow CPA is interested in these Olivers... We just put a chrome straight pipe on our 1950 with no liner, do you think the chrome will tint? I am hoping not, as these are basically air cool engines.

Thanks for sparking this interesting discussion forum.

Jim,
It's great to see an expert offering advice like
this.
I have a 1900 with the 4-53. It has a clean engine
that doesn't leak oil, but tends to wet stack if
not put to work. Is the wet stacking something to
be terribly concerned about or is it ok if it goes
away once the engine is warmed up?
Thanks

I have a 1967 Oliver 1950 with a stock 4-53 Detroit that I part time farm with.I may try and get 15 more horses out of it.

Back in the early 70's we had a 1966 Oliver 1950 that had one size larger injectors and had the rpm's turned up.It was alot stouter than the 67 model I own now.Every 4 hours pulling a 6x16 Oliver plow would empty the fuel tank on the 66 model.The 1967 model will go 5 hours on a tank pulling a 21ft Krause disk.

I have always been a big fan of the Detroit Diesels and despite the fact that they leaked oil I still think they were a great old motor.A 4-53 Detroit running a straight pipe at 3000 rpms is one of the sweetest sounding motors ever built.I cant wait for it to dry up so I can get in the field with my old 1950 and wake the neighbors up.

It might suprise you that you could have your 15 Hp. and get better fuel economy at the same time. Good luck with your 4-53. As for the Detroits leaking oil, that is one of the misconceptions about them that are out there. A properly done engine leaks no oil!!!Jim Bute

We don't pull, but we do have an Oliver 1950 with a 4-53. We use it mostly for pumping water now but the engine (tractor) just seems to run and run. Only problem is oil leaks. Do you mind if I have any questions on the engine to forward them to you? Our local mechanic bumped this tractor up from the rated hp of 105 to around 120 hp.

Feel free to fire me any questions that you would like about your 4-53. I do not know how much of a load you are putting on that engine just running a pump. Perhaps it is just wet stacking due to low combustion temps and lack of load. There are several ways to check and correct that condition!!! Jim Bute

All Detroit engines leak some oil. Guess they never bothered to fix the problem. My great Uncle used to have several semi trucks with detroits in them and every one leaked oil. Good engines in all other aspects though. He has converted the dump truck fleet of 47 to late model Macks recently. Harley-Davidson motorcycles leak some oil. I saw a NEW Harley a couple of months ago in a dealer showroom with a piece of carboard under it because it leaked.

When I worked on Detroit Diesels I always offered my customers a discount if they could find any oil leaks after a major rebuild. Usually going in and correcting mistakes that happened in the past was enough to correct those leaks. Another thing to consider is the drain tubes on the air boxes of older engines. They are there to drain off combustion by-products. One such product is unburned fuel in the air box are. When that washes the carbon out off the air box floor via the drain tubes it is often mistaken for an oil leak. There are a couple of neat and easy fixes for this. Jim Bute
