I found an sc300 with 1jzgte swap and wanted to buy it, but currently it is untuned and is running rich. During idle it flucuates between 9-10 afr and cruising about 10afr with occasional 11afr. Would the rings wash out if driven like this for a few hundred miles? I asked the seller to bring some extra plugs so that it can be swapped out every 100 miles while driving it back. I don't even know if that is necessary.
or I should ask, has anyone ever driven the car like this for couple hundred miles and been ok?
thanks

trailer is less expensive than an engine rebuild.
I wouldn't even be buying a car in such bad shape.
and if it is a "steal" then you can afford a trailer.
otherwise... you are a dreamer.

Well, I dreamt of doing some extensive googling and as long as their is spark and the timing is right most if not all of the gas should fully combust. It's not like the car has a carburator; this car is spraying mists of fuel. The only way i think there would be a wash is if the spark plugs fouled out in one of the cylinder and there was just gas pooring in there. Therefore, I'm just going to have some extra spark plugs to change them every 50-75 miles or get a wire brush to clean the tips. I'm also going to have the seller change the oil to 20w-50 with lucas oil stabilizer. I'm also doing a compression test on the motor anyway. btw, the seller is meeting me half way distance.
Lastly, have you had an experience where your oil began to thin out and spun the rod bearing?
