1972 wheel horse commando 8

[upstate yank 219]

well guys; i have a very nice 1972 wheel horse commando -8 ;it needs a seat but that is no issue as of yet' i did some trading as  for years i have collected  and restored the older Coleman lanterns and stoves for years as a hobby even certain ones from across the pond 'England  that is plus other countries so make a long story short i did some trading with the lanterns and lamps no cash was added as i had over 200 lanterns and lamps so the ones i traded  won't be missed ;the thing is yes it smokes bad and i was told that during the trade but after changing  the head gasket i thought that would help but it didn't ;other then the smoke the motor spits oil out of the muffler so i wonder if it needs rings or just maybe taking the head off again and using the sea-foam or the mystery oil down in the piston sleeve and let it soak for a day or to or is it that far  gone where it needs an a over haul 'really it is to nice to use for parts 'so i ask  here  your  thoughts ;

If it's letting oil out the muffler it isn't too likely that the penetrating oil would help but we've all seen weirder things happen.

I'd say try it. Can't hurt.

 

Certainly time for a leak down test on that engine.

it smokes bad and i was told that during the trade but after changing  the head gasket i thought that would help but it didn't

While the head was off the engine did you take a look at the condition of the cylinder wall? Have you removed and cleaned the crank case ventilation (valve cover)? If the crank case is not properly ventilated the internal pressure can push oil up past the rings into your combustion chamber.

That and too much oil is as bad as not enough, there is no snake oil that I know of that will fix a bad condition in an engine. Smooth out an idle, clean a little carbon from some valve's, OK. I'd start if you haven't already, drain oil and then add to the correct level. Clean engine breather and see what happens. IF you have to rebuild, not that hard to do. All the help you could need is right here at your finger tips. Good luck

thanks for the reply and yes i did check the cylinder wall and it seemed smooth ;and no i haven't checked the crankcase ventilation but that is next 'really i never thought of that ;i did drain the old oil out of it and it was quite dirty ;so once i check the valve cover i will add fresh oil and hopefully it clears up if not well we know what needs to be done ;again thanks

thanks for the reply back as i appreciate it;the oil level was good but the first thing i did once i got it home i drained the old oil out and then replaced the head gasket thinking maybe that was bad but that didn't help ;as of now there is no oil in the motor but i will add fresh and really i never thought to check the breather but that is next ;once the head was taken off i cleaned what i could off the valves and the top of the piston ;the piston sleeve was smooth which is good ;with this cold spell we are having it will take some time to get to the garage and check the breather and yes hopefully that is the issue ;thanks again and i will let you know what happens ;

I had a 312-A with the 12 HP Kohler magnum on it. I adjusted the valves on it, and then it started leaking oil around the valve cover. So I pulled it down again and used new gaskets and put it back together again, Then it started to smoke, I thought I don't remember it ever smoking this bad before. So after talking to some people I pulled it apart one more time and found I had put it back together wrong had the one piece in upside down. I think I had it apart 3 or 4 times before I got it straightened out. Once I fixed it it quit smoking. So it would definitely be worth taking it apart and checking it out. Check a manual to make sure you get it right the first time, unlike me  lol

It had been sitting quite a while since it last was run, there a slight chance it could have a stuck ring. Spray a good amount of carb cleaner down the spark plug hole and let it sit a few days. You might flick the flywheel back and forth a tiny amount to work the cleaner and rings   Before you start it upsquirt a small amount of oil in cyl to lube it back up then spin it over with the starter to blow excess cleaner and oil out

What did the old oil look like?   If the oil was really black an sludgy I would use cheap oil and change it a few times using it lightly. If it still smokes and you want to keep it used motor honey in it. It will help with the smoke. I have had a few like this some times they work it out and become good engines. Good luck.
