47 Flattie w/ supersonic L-Head

I just purchased a 47 on a farm auction last weekend. It is literally a barn find dream. It has set inside a brick barn since 91. The guy had done a pretty good job of restoring it in the late 80's to original. It is in very good condition w/ a white soft top. The engine tag says it is a supersonic. I am a Willys fanatic but arent theese engines pretty rare. Obviously it is not the original engine as it has a Kaiser tag on it but neat anyway.

Before the auction, they got it out put new fluids in it and it started right up and runs good. It shifts fine and runs down the road great but smokes pretty bad. I put some sea-foam in it and have started it every day or so and ran it down the road on about a half-hour trip.

Any ideas on smoking, I dont know condition because the gentleman that had it is gone. I assume rings but any tricks or ideas after it has set so long???


Thanks,

Bryan

 

Seafoam will cause smoking until it burns through the system, was it smoking before the Seafoam?

 

Yes,

It was smoking before and that is why I put it in. But I have only ran it about a half hour or so since putting it in and worked it a little on a gravel road w/ some hills. It had not been started since it was put away in 1991 but it does seem to smoke pretty good when you give it some throttle. It has a oil smell or odor to it.


Thank you,

The supersonics are rarer than the standard engine. Supposed to make a little more compression than the standard L head..equalling a couple more horsepower.

I may have missed it but what color is the smoke? white or blue?

 

I think the smoke is bluish in color and has an oil smell to it. But honestly I have only ran it for maybe a total time since it has been stored about 45 minutes or so. Would putting any restore or some kind of lubricant possibly help it or just do the compression test????

Get some snake oil from the traveling salesman.

 

Let me clarify my statement.. Any oil additives are nothing more than "snake oil" . They are not going to fix anything. Those engines are pretty easy and cheap to rebuild. Whenever you get a chance like this winter, I would just tear it down and rebuild it.

 

To really know what you got, put the Jeep under a load untill it's good and hot. Work it for a hour dragging or pulling something to put a load on it. Alot of these Jeeps that were rebuilt never get a good workout and do a lot of idling. These run rich to begin with alot of crap loads up in the exhaust. After the work out do a compression check.

 

Thanks for the advice guys,

I will do as stated.
