6070 need advice Engine Smokes!!

I recently bought a 6070 and it smokes something terrible drips oil from the breather tube!! I know nothing about the 6000 series tractors other than I wanted one to help my son-in-law with haying. Hour meter shows about 5000 hours. I am not sure where to start, looks to me like a complete overhaul. Could it be something simple like oil from the turbo? I have rebuilt two 426s but I knew they needed overhauled. It is a late model with improved thrust bearing, it starts hard but doesn’t knock, oil looks good no water in it. Injection pump is not black so I guess it has been rebuilt and the starter looks to have been replaced. Engine does not appear to have been worked on, bolts and nuts do not looked to have been disturbed. Any thoughts are welcome and appreciated. Thanks

Dr. Allis what do you mean when you said:  Injectors installed backwards will do weird things

Son in law has a road tractor that had blow by but used no oil.One day i noticed no blow by and he said when he changed oil he put in a gal of LUCUS. Might it a try.

Thanks guys I haven't really run it other than to load and unload then put it in the barn. We have been busy with hay. The smoke is blue and I haven't had time to crack the lines to see if it is hitting on all four. I did notice that when I shut it down I could here the turbo spooling down always a good thing to here. I am reluctant to run it much with the way it is blowing blue smoke and not knowing anything about it's history I bought it at an estate sale the owner had passed and apparently he was a loaner that know one ever talked with, not even his family. I don't like that it starts hard it should fire right up at these temps.

A whole lotta fretting over nothing !!!  Throw the throttle wide open and take it down the road for a couple of miles!!!

You might try giving er a stiff drink of some Stanedyne or Howes fuel conditioner in the diesel fuel, then give er a workout. Darrel

Blue smoke and hard starting can be indications of low compression.  Might need a ring job.

Dads starts just fine down to about 45 degrees. It had become harder to start and then began missing one day while baling. The pump needed to be overhauled. It starts much easier and smokes less. The 6000 series do smoke when at idle. And it has a blue haze to it, above 1,000 rpm it clears right up. Like the DR said, throw her open and take it for a spin. .

Steve    DITTO   The factory ether button on ours gives a premeasured shot and only if the engineis is being turned over.     I never press the button unless I got lots of white smoke.    I have never heard it "rattle" like they do when you spray ether in the air cleaner.    How about it Dr. Allis, is the "factory" ether injector still a no-no?

Same tractor needs a glow plug below 80 degrees and will cough a little at first startup but it's a fuel sipping bugger. Good luck!

Since it has been sitting I would highly advise some Seafoam in the tank and the crankcase before you change the oil. Run it for at least 15 minutes once its up the full temperature. Run the engine at different rpm’s. It cleans the internals very well and if it has carbon build up on the rings it will clean those up also. I had a engine that smoked horribly when I finally got it running. Ran it 15 minutes and it continued to bellow blue smoke. Put Seafoam in the fuel tank and the crank case and within 5 minutes it started smoking less, after 10 minutes the smoke was almost gone. Changed the oil and filter, fresh oil, and more Seafoam. After 5 more minutes it completely smoothed out and has yet to smoke anymore. Changed the oil and filter again and the oil was jet black when drained it. I thought I was looking at an overhaul but it cleaned up the rings and has ran great for 6 years now.

we have a 6060 with 9192 hours, second owner, bought tractor in early 90's and this spring when it came out of winter storage it started doing the exact same thing, hard starting even after engine is hot ,smokes blue smoke an has a lot of blow-by with oil dripping out breather,( Never had oil or noticeable smoke out breather tube)
