Good one
what if it still produces alot of white smoke after replacing injectors?
I am intensely interested in installing a 4BT Cummins in a Farmall 400. Thusly, I watch People, like You, to learn any little thing that l can. Fergieman
Love it. Thanks for sharing!
Cummins V8s, Mack 998s, Cat 3408s always had a thump and cackle to them with the Mack sounding like a locomotive. Scanias do the same thing.
No this guy a dreamer not mecanic basic white smoking yes injector leak this engine showed drive for 1000 mile before failed on full injection open
I put a turbo on a 903, but did not change the cam key, is this a problem
Yes, they use an offset key to advance the timing. Also the early blocks didn’t have internal ventilation. It would cause oil starvation. The block not vented internally the oil would build up into one rocker cover ( bank ) and not return to the sump. The remedy was to remove the engine barring gear that was integral the compressor mounting cover. You tapped and threaded bore hole the barring gear-shafts passed through and installed a hose mounting nipple with a hose that ran to the rocker box.
Let me ask you something, was this engine an early build, and was originally naturally aspirated? It’s when Cummins added turbo’s that the problems began. The naturally aspirated engines had an issue where oil leaking down the intake valve guides was “ coking “ on the intake valve heads, and clogging up the port. As the build up of this baked oil restricted the engines ability to breath it developed smoking problems. Cummins decided they would initiate a program to deal with this as what the described as a “ social acceptability problem “ and added a turbo. That is when the trouble started. Boost pressure was causing the intake valves to float open at maximum boost pressure, so the they added more spring tension. They then had trouble with the valve seats, and valves dropping. The hardened the valve keepers, and beefed up the rockers. Then the pockets in the cam followers pounded out, so they addressed that, and the tips of the push tubes. The next weakest link was the bronze cam follower pine that carries the cam follower rollers. We were the distributor for Cummins products for Ontario Canada. We had some ( for that era of time ) large truck leasing fleets that had a lot of these engines engines, and they where blowing up left right and center while we where trying to catch up and retrofit these components into the engines as they where towed in. The first thing you did was get a antifreeze basin and position in under the oil pan drain plug to catch the coolant when you removed the plug. The dropped valve would smash the hell out of the head, and the injector and the copper injector tube. The coolant would down flood the cylinder, and as you know you cannot compress a liquid according Pascals theory, but it didn’t stop the piston from trying too once. So lots of towed trucks, and late deliveries of cement to the batch plants and hurt feelings all round it may have contributed to the failure of that up and coming truck leasing company. Some said the got too big to fast, but there may have been more too it. Meanwhile… the older naturally aspirated engines kept pounding up and down the road puffing out its smoky haze till the cast iron webbed oil pump that weighed what felt like 25 lbs or more dropped into the oil pan, and that was the end for that engine. You only have to get hit in the face once while laying on a creeper dropping the oil pan to “ No gonnie do that again, gonnie no ! “ The construction version of the same engine known to us as a “ 265 “ there where two versions of this engine, so don’t get confused here if your that old, but the one with the same rocker covers as the 903 but didn’t have 903 cast into them, they where mostly found in construction machinery like cranes, and large rubber tired loaders where all natural aspirated models. Turbocharged marine engines were capable of 420 hp.
The early naturally aspirated engines were far less problematic than the later turbocharged engines. I worked on many of these. They where a valve train nightmare, that and oil pumps falling into the oil pan. Don’t miss muscling those cylinder heads over the steering tire and up onto the the block. We didn’t have shop cranes over the truck bays back in the day.
you should probably mention that it's common to have a bit of white smoke when cold starting diesel engines in cold weather.
This guy is a wise old school mechanic
I need that turbo part number!! Please!
Possibly an ST 50.
M2 Bradley fighting vehicles are still powered by these,rated 600HP.
Built by Cummins not cummings.
I have white smoke on my 94 Nissan FE6 it burns my eyes. It's been like that but no severe misfire or power loss that I can tell... Im going to peek down into the cylinders with my scope. No cat converters or def, it's mechanical and old.
Love it. Thanks for sharing your knowledge of the Cummins with us.
Great video. Made me wish I in a class on these things. Long story short I just got a Dodge Ram 2012 ST 3500 over 200k miles and soon as I got hot from the dealership I noticed smoke coming from underneath the front side of truck with a strong smell like burning fuel. I'm still trying to figure out what it could be before I take it to shop. I only had it a few weeks, it only dose it after I've ran it a while can you please give me some advice on what I should do or what does it sound like?
Order a cheap borescope and take out your injectors or glow plugs and look, that's what I'm going to do, same problem. Fingers crossed 🤞
@@crazyDIYguy ok thanks for the info but after calling around and doing a headache of research I finally discovered the problem and I dosen't seem like it could be something so simple. It actually was the ring gasket that dose between the V-clamp on the turbo exhaust down pipe. If you see soot residue anywhere down in that area then you have an exhaust leak.
@@carnelsullivan6009 no kidding, I'll see if I have something similar going on. White smoke that burns my eyes. Thank you
They are well respected and loved in Australia. They changed road transport forever in that country.
They certainly did.
Those engines do very well in Bradley’s
they reminded me of the sound a 1950 ford car w/flathead v8 and dual exhaust makes when going thru the gears , or just going down the road . always loved that sound .
This has been happening to many people with the 2.8 diesel in the Canyon/Colorado because GM decided to install injectors that are running to close to the max rail pressure. Causing the injector to stay open and burn a hole in the piston within seconds of the injector failure. You don’t have time to shut the engine down before it’s destroyed. Years effected are 2016-2018 In 2019 GM changed the injectors to handle higher rail pressure and fix the issue. GM will not update the early years engines. Typical….
Over fueling. A lot of them newer Cummins have that problem. That’s why I like the older mechanical 24/12 valves because they don’t have that problem.
So it's possible that the injector on my 2cyl diesel tractor is doing the same thing. I'm getting lots of white smoke. It doesn't start though. I'm only getting 300 lb of compression max. So maybe it's something else.
I have a VT504 (VT190) in my International and I like that little engine

What about white smoke when off the pedal and black smoke when you hit the pedal down not much black smoke though.
Truckers called them nine O nothings!!
Because of lack of power??
The TV show "Movin On" Kenworth had a 903 engine in it.
That certainly sounds sweet
Sure does! What do you have for your boat?
@@dieseldoctorlane I have a Gardner 8LXB
Qwantwz hp??
What if there’s only white smoke occasionally? On an LML duramax
OK smoke means to get it fixed. But what if I only noticed the whitish smoke when the headlights were on? It is a Yanmar 324 24 HP tractor.
Hello. I have a Mercedes sprinter 2008, i have no white smoke when cold,when warm i get white smoke only at idle but clears when start driving, white smoke do have a diesel smell to it, can you please tell whats the cause of this, been doing it for over a year now
Please, please your advice. Hard to start, then big white smoke for 1-2 seconds, and black smoke. Then ok. Vehicle is 1996 Toyota Prado 3.0 Turbo Diesel.
Where is Mr. Harper's shop located?

So welcome
What would cause the injector to get stuck?
Sticktion ( asphaltine) look up hotshot anti sticktion)
