Oil in the air box.

On the 850 there is wire mesh in the breather cover on top of the valve cover that helps to prevent oil drops going into the breather pipe to the airbox. Not sure if 750 also has this wire mesh, but maybe yours has been removed?

Yes, my 750 has this wire mesh as well, and it is in place.
Thanks for the tip.

Stuck rings can be freed up sometimes using Marvel Mystery Oil in the cylinders, or in the gas, so you might want to try that if the engine is actually burning oil like suspected.
Good luck.[/QUOTE]

Do you suppose it would be alright to pour some Marvel Mystery Oil into each cylinder, slowly turn the engine over a few times with the kick start, and let it sit all winter? Would that hurt anything by doing that? I would just need to be sure I drain and change the oil and filter like I normally do next spring.
Has anyone had any luck freeing up sticky rings this way?

Your friendly GM dealer...

my departed ex- father-in-law* was a service manager at Buick dealer many, many moons ago. He used and swore by the stuff. that man knew his stuff, unlike most of the ones I see today.

I've used it both as a pour in the carb combustion chamber cleaner and used it as a fuel system/top end cleaner, when I used it way back when.
it was very good stuff. (coming from a person who works at a Ford dealer)

*wishing He was still around... :(

procedure - 1 Internal Engine Cleaning

1. Warm up to normal operating temperature.

Important

In order for the cleaner to be effective, the engine must be warm.
2. Disconnect negative battery cable.
3. Remove spark plugs.
5. Pour 3 ounces of GM Piston and Ring Cleaner (P/N 12378549 12 ounce bottle) into each cylinder through the spark plug hole.
6. Cover the cylinder head and spark plug holes to prevent debris from getting into the combustion chamber and to prevent excess evaporation of the cleaner.
7. Allow the engine cleaner to soak for a minimum of 2 hours.

Notice

After the minimum 2-hour soak, there may be some cleaner left in the combustion chambers. Do not start the engine until all of the cleaner has been removed from the combustion chamber or severe engine damage may occur.
8. After the minimum 2-hour soak, remove the remaining cleaner from the combustion chambers by placing shop towels over all of the spark plug holes and cranking the engine through a few revolutions.
9. Install the spark plugs and spark plug wires.
10. Start the engine and run only enough to reach normal operating temperature.
11. Drain the engine oil and remove oil filter.
12. Install new oil filter.

I was trying to see the best way of removing the GM "P & R cleaner" and ripped this off from another site...
***After a 2-hour soak, you will vacuum the cleaner from the engine...***

***note, the stuff is probably flammable***

so be very careful with it!!!! and it may EAT paint!!!!!!!

Those early Saturn engines had a problem with piston rings getting carboned up. An engineer that worked at the factory told me they recommend MMO in the gas tank to help free them up. That soaking technique is more of an immediate fix, or attempt to fix anyway. Worth a try.

Thanks guys!! I'm going to give this method a shot. It's worth a try to fix the situation this way vs tearing into the engine.

Another thing I used to do with cars with sticky rings or valves was take the breather off the carb, warm up and rev the engine and pour an entire quart bottle of kerosene lamp fuel as fast as you can down the carb to where it almost stalls out and keep doing that until the bottle is empty.
This stuff is cheap, (back then less than a couple bucks a bottle) and comes in plastic bottles in places like WallMart where the keep housewares and the decrotive kerosene lamps. It even comes in scented aromas in different colors or non-scented clear.
I always did this at night because it would literally fog up the entire neighborhood with a heavy dense cloud of smoke.
It worked really well and made the whole neighborhood smell like vanilla.
I have a 5 gallon take on my GS750. I might try dumping a whole quart of it in the gas tank and top it off with 4 gallons of gas and like you say...take it out and run the snot out of it.
