Rolled my EX3200 and need help

[Neat 1500]

blue smoke indicates oil burning. have you run it for a while to see if it clears? does the engine sound any different? i have rolled mine on its side also and had it righted in 5 minutes also. i used my decompression lever before firing it up but it was all good, only did minor damage to the 3PH lift L/H arm. sounds like it has a gut full of oil its trying to clear.

Tonight I changed the oil in case there was diesel fuel in it. The oil was pure and did not have any smell of Fuel. Started it after changing and no difference. Still a lot of blue smoke and sounding like only 2 of 3 cylinders firing. Pulled the 3 injectors out. All 3 had a lot of carbon buildup so my hopes soared that maybe an injector was plugged. Cleaned all 3 and reinstalled. Started it up and a slight improvement in power but still feels like 2 of 3 cylinders and it is still smoking. I ran it for 20 minutes and no change. Based on the input from everyone the smoke has to be oil being introduced to a cylinder (ring?) and
the miss might be a bent valve? It breaks my heart to tear an engine down with 60 hours of operation so i will wait to see if any one else has suggestions of what i can look for first. Do you take compression tests on diesels from the injection hole with a hand held gauge? What should the compression be?

pull the valve cover and check clearances. I just had a tractor that had been dropped and it ended up have 1/4" valve clearance on one of the valves. once I figured out what was going on it ran great.

Yes, injection hole. Check all 3 cylinders and most likely 2 will give you the answer as to what the compression should be. Blue smoke that stings your eyes is unburnt diesel fuel. The clicking sound is disturbing. 5 minutes on the side shouldn't be long enough to cause internal problems. When it "clicked" was there any movement of the crank at all?

Note this requires a special 'diesel' compression tester. A tester for a gas engine won't read up to the 400+ psi you should have.

A simpler rough test is loosen the fuel line to each injector, one by one. If a cylinder isn't firing then diverting its fuel won't drop the rpms. But work safely - there is a danger of serious injury if you inject that high pressure diesel into your skin.

5 minutes is more than plenty of time for hot oil to infiltrate past rings and lock it up. The miss is either a pinched injector line or low compression which could be the result of bent rod(s).IMO.

The bad thing is there isn't any extra room for un compressible's in a diesel and it very well may have bent a rod or 2 and like these guys have said a compression test is IMHO mandatory at this point.

The smoke will be there a long time afterwards even when everything is good the exhaust will be soaked inside and it will just take time so thats not a real good indication of an engine problem for now fwtw. good luck

Hi guys, Thanks for contributing. I cracked the injectors while running which did produce fuel from each line as well as a noticable reduction in RPM from each individual cylinder. Also, although I had removed the entire air cleaner tube, filters and assembly I did not get into the actual intake itself. I will do so tomorrow night.
On the first night of the rollover the click was the starter hitting solid. No motor turnover. I hit it with 2 short attempts of less than 1 second each and then stopped until the nest night. On noght two it clicked turned over at leats one rotation and on the second try it fired right up.
The motor functions to well to have something wrong on the lower end. It seems to have compression on all cylinders (injector crack test) which should eliminate bent or damaged valve train items. However the continuation of the smoke after all of these nights of running gives me worries. It does not appear to be burning away like one would hope. The smoking has almost completely disappeared at idle but at mid throttle it has stayed mostly the same as the first night....very heavy and rich smelling of diesel. It is almost like it is running WAY to rich rather than it being oil burning.
There is absolutely no exterior physical damage to anypart of this tractor.

What controls the amount of fuel going into each cylinder?
Could there any check valves, electronic relays or fuses that might control fuel that could might have been impacted by the rollover?

I am having a hard time locating a Service Repair manual for this tractor so hopefully I can find one with schematics soon that I can buy.
Thanks for your help guys!

I'm a fairly new diesel owner that hasn't experienced any problems yet but I know the concept well. These are my thoughts but I wouldn't go tearing your engine apart on account of them.

Everything that you are telling us is pointing to a bent rod although I'm surprised at the 5 minute lockup. Car Doc thinks it can happen so I'm sure he has seen it before. It would be a very odd coincidence that you developed a starter problem at the same time as the rollover so I have to assume that you had a hydraulic lockup. If a rod is bent, that cylinder may not have enough compression to ignite the fuel charge which could be the rich diesel smell and smoke.

How is the engine power and smoothness now? The noticable reduction in RPM on each cylinder is something I wouldn't expect of a bent rod. Have you run the tractor under load to get it up to operating temperature to see if the smoke will clear up. If it doesn't get better after doing this my next step would be to check the compression.

Diesel engines gets its fuel from a precision high pressure pump that meters the fuel charge into the cylinder, very similar to fuel injection on a gas engine but mechanical. For the most part these pumps are reliable but they don't tolerate dirt or water very well. Maybe the tip over stirred up some junk in the fuel system causing a rich condition? Maybe everything is OK and it's still burning off fuel or oil in the exhaust manifold as Car Doc mentioned.

I second running birds suggestion checking rocker arm clearance.

In my limited experience (2x) with a vehicle which was cranked against an oil locked piston the results were disastrous. In both occasions the engine even appeared to run normally, but in one case the next week and in the other 2 months later the engine threw a rod out the side of the block.

The starters have to have tremendous power to overcome the compression of a diesel engine and if it tried to crank and was stopped by the oil on a piston, then something probably was damaged in the internals. I am not saying that it was for sure or that this result will be yours, but that is my experience only.

I imagine that this tractor is still under warranty? You would be careful what you do that might compromise that with unauthorized work, but I would get it checked out or check it out myself. And it does involve some major tear down, but it will be less expensive than replacing the entire engine block.

Just my opinion from my experience.
