GL1100 smoking and spitting oil from left side

Postby BRS » Sun Jan 17, 2016 5:57 pm



Hello. I just recently was given a 1982 GL1100 aspen with 70,000 miles. Its been sitting for a couple years but it is running good and most everything seems to work on the bike. The problem is I am getting exhaust smoke from the left side. At first it was really bad and was spitting oil out the left exhaust. The oil that was in the bike was very thin and it was about 1 quart over full. I changed the oil to the proper weight hoping that was the problem and it reduced the smoking but not completely. It seems if it sits idling for a while it seems to get worse. It will fill my garage up with smoke after about 10-15 minuets idling. I keep it on the center stand and ran and drove it a few times but it still seems to smoke. Does this seem to be the valve seals? I also noticed a few drops of antifreeze from a hole by the water pump so that may need to be replaced also. I had a Goldwing when I was in my twenties about 30 years ago but I haven't had bike since or ridden in 25 years so I am excited to start riding again. I have learned a lot from this site and I appreciate the help. Also where is the best place to buy parts now?
Thanks

Older Wings are known for having oil leak down into the left side cylinders while sitting on the side stand, especially if they have too much or too thin oil. I assume you have drained and refilled with the proper oil so wouldn't worry unless is continues. My question is why too much and too thin. Sounds like the carb floats might have leaked and drained some gas into the crankcase. Something to keep an eye on as diluted oil can screw an engine up in a hurry. Sitting like that the carbs might need cleaned.

When I first drained the old oil it did smell like gas so I am sure your suggestion of the gas leaking into the oil was what happened. I dont know who did the prior maintenance. I just took it out again for a quick ride and when I got back it was smoking even more now.

First always shut off petcock when shutting off motor. What I would do is fill fuel tank and add 8oz. of seaform to the fuel tank. Run motor for awhile and let seaform do it's thing.
You can also when running motor. Shut petcock off and when motor starts to sputter for fuel turn petcock back on.
Before running motor to much replace timing belts. Because if they break they will take out valves.

Another point that was raised in a similar thread is that you may have gotten oil down into the manifold and muffler which will smoke for quite a while.

Thanks for the suggestions. I will try the sefoam in my tank and look into changing the timing belts, they dont seem too difficult. I have let the bike idle and warm up for about 15 min and drove it around for about 15 min a few times so I think that would have been long enough to burn off any oil that may have collected in the pipes.

I might even take the exhaust off and clean/wash it out. If you engine was over full, that would be where your oil in the exhaust could come from.

Also, get at those timing belts as has been mentioned here.

On the subject of timing belts, these all fit but are are much less expensive than the OEM, also usually in stock so no waiting for an order to come in. Ask for them by number at an auto parts store and hopefully you don't get the worker that has to have a vehicle make and model to find anything. If you get farther into the engine I can send you a link to a crossover list of auto parts that are interchangeable, most at a much reduced cost. Radiator hoses and fan switches come to mind.

Pretty much the same but from a different forum.

^^^ I resurected one a few years ago,took hours of running to totally stop smoking!!
Do your maintenence and drive it like you stole it for a while,keep an eye on oil pressure and water temp,if it still smokes after that dig into it.

Hello. I put seafoam in the tank took it out a couple times and gave it a good long hard drive. It smoked about the same throughout the drives and when I got home it was smoking pretty good. When I got home I gave it a few good revs and it was still spitting out oil from the exhaust. I did a compression check and I am getting 95 on each cylinder. I did it with the throttle open but I didn’t put any oil in the cylinders. I only had access to a harbor freight tester and the reviews said they read low on smaller engines. The compression seems low but at least it is consistent. The bike runs good and seems to have good power. I am thinking maybe valve seals or maybe even guides. Also the plugs look good. The bike is always on the center stand.
The water pump is dripping a little and I know I need to change the timing belts and I am sure the carbs could use a going through. I just don’t want to sink any money into the bike unless I can figure out the smoking issue.
Looking for suggestions as to what I should try next.
Thanks

Update, I changed the valve seals and that cleared up my smoking problem.
Thanks

BRS.......I was just reading all the posts under your thread, and I was betting that you had gas leaking past the fuel pump and going staight down into the engine crankcase. I think that is what is happening now with my 83 GL1100 Interstate. I was getting a half quart of gas mixing into the crankcase oil, even as the engine was running. So, the gas cant enter via the cylinders since they are running. The only logical place would be from the fuel pump, maybe due to a bad gasket there.

You said that you solved your problem by putting in new valve seals. But I bet if you look at your engine oil level sight window, you will see that your engine oil level is rising over time, and you probably have thinned-down oil with gas in it. Because if your valve seals were the problem, then you would be losing oil and not have the oil level rising.

Let me know what you find out.
