We have a Allis Chalmers M100 road grader.
It has been stored in a shed for about 25 years, without use.
We recently decided to use the grader & checked the engine oil. That was ok & also all other fluids.
We worked the grader for about 15 hours.There was a small amount of intermittent smoke from the sump breather pipe. The engine exhaust was normal. The engine was using a small amount of engine oil.
After the 15 hours however, the sump breather pipe was emitting a constant flow of smoke, with some oil also.
There was air pressure in the sump; as when the dipstick was checked (with the engine running) there was pressure emitting from the dipstick hole.
Can anyone suggest the answer to the problem ? We are wondering if the piston rings are sticking & allowing combustion gases down into the sump. Is there a way of fixing this, without having to strip the engine down & renewing the rings ?
Thanks
