656D continuous exhaust smoke

My farmer neighbor accross the street has a 656D, 282D that is smoking...a lot. I have experience working on diesel engines and have listened to this one but not touched anything yet. I owned a 460D and worked on that when I had it having r&r the pump for rebuild and all six injectors but that was 20 years ago. Here's what I know: It will start right up, cold or hot, normal with glowing. Idles good, has ok power-they only use it for light utility chores mostly brush hogging around fields, Its not making oil or using oil. Not losing any coolant or making any. But running it leaves a steady column of white smoke and may have a slight miss. He's not mechanical at all and says a few years ago the dealer had it and had the pump rebuilt and I see the injectors look like they were all out recently too, hes not sure about the details, but they let it out of their shop like that. The smoke never clears up. They bought it new and Its almost at 10,000 hrs with no overhaul that he knows of. The high hours would leave me to think its just whipped out but if that's the case, i think it should start hard. The filters and fuel are all good. My first guess is the pump timing is off? Then possibly a dribbling injector...but that should yield a solid miss and gaps in the smoke? They're not interested in an overhaul, they will just cut their losses if it comes to that. Any tips from the 282D gurus?
 
It can be anything from low compression to a bad injector. Loosen each injector line one at a time , watch the exhaust , when the smoke disappears you have found the cylinder at fault. Then u can check the compression on it. Should be up around 350-375 lbs. I have seen the air cleaner get water in them and freeze and cause a no start.
 
My mf 165 had the wrong injectors in it when I got it. Same symptoms exept maybe darker smoke. A long shot but maybe worth checking since sounds like they were replaced recently.

That can happen on your engine because your injectors are four hole tips, and the AD3 and AD4 Perkins injectors are turned 90 degrees from other Perkins engines. The IH D282 uses single hole injectors so that won't happen.
 
I Would suspect an injector if it is not a heavy white smoke since you say it has a slight miss to it. If not an injector then I would suspect a low pressure setting in the pump not pushing the correct pressure to the injectors. Not familiar with the 282 engine just going by my last 50 years around all the engines we have here of several different makes we have IH, Deere, Cat of several vintages, Cummins, and a Pukins. Cat set the timing on our D-4 late and it smoked like a steamer under load with no power. This was 50 years ago. We retimed it and was good after.

Won't be low pump delivery pressure/flow since the engine will run..
