Oil leak on 8v92

[busnut104]

I have noticed quite abit of oil more then usually coming out the left slober tube, what could be causing this, could it be the blower seals and if so how much of a job to fix. I will say that I have been starting the eng. and pulling in and out of the shop to work on other things and some time I have left it idlel for a while, could this be just a build up. I do plan on getting it out for a long drive when the weather clears up, but just trying to plan for the worst. The eng. has just a little over 100,000 miles.

It probably would be better to minimize your idling. The engine never gets warm enough unless it is put to work.

For what it's worth.

ANY Diesel engine likes to work.  They don't like to idle for long hours-especially 2 strokers.  Personally- I believe it better to let the engine sit than to start it frequently just to idle it.  Diesel engines can sit for months without being started without damage (so long as you cover the exhaust pipe or the bus is indoors).  I have an Onan 6kw 2 cylinder air cooled Diesel that was in storage for 7 years that I did nothing to prepare for the storage.  Took it out, pumped fresh Diesel into it and it fired up like it had been running the day before.  Now as too a gasoline engine-they should be run once a week to keep from getting gummed up and not to let the gasoline get over 2 months old.  Diesel fuel with stabilizer can last for months even years in a tank.  Good Luck, TomC

Tom C.,

What do mean "cover the exhaust pipe"? I have never heard that expression before.

Thanks,

Paul- if you are not going to start the engine for awhile, covering the exhaust pipe to prevent water from coming into the system is a simple way to prevent rusting since most likely at least one of the exhaust valves will be open.  This usually applies to a vehicle with a exaust up pipe, but humid air blowing into the exhaust can be enough to introduce enough moisture into the cylinder for rust.  Good Luck, TomC

Got it!

Now I remember from my youger days working on a farm, covering the exhaust with a can.

Thanks TomC

Happy Trails,

I just love all the answers I got from my question, about the oil leak, I have had DD for over 40 years and still have one in the bus and two in dump trucks on in a excavator and one in a grader, so I know about idling, and not starting for a short period of time, but when you have to move the vehicle to get another one in you have no choice, but in all these years I have not had to have a blower resealed or a real poblem with excess oil out the slober tubes, so I thought I
would ask if anyone else had this problem and what was there solution, but I got everthing else but. So again has anyone had this problem and what did you do to solve the problem. and if blower seals is it how much of a job is this.  Thank you for a real response to my question.

If you are getting more oil out of the slobber tube on one side than the other, most likely you have broken one or more piston rings.  You can check this out without taking the head off.  You open up the inspection air box covers on the side of the block.  For the cylinder you want to inspect, just tap the starter around till you see the rings through the intake ports.  Sometimes you can tell which cylinder is the bad one by the excessive oil, or just plainly looks different.  You can rotate the rings on the piston to inspect the full circle of the rings.  Good Luck, TomC
