Diesel cleaner?

Diesel cleaner?
Is it a good idea to use diesel fuel as a cleaner? A guy was in the shop yesterday telling me to put some in the crankcase and let the motor run for 15 min, then change oil.The 350 has not run in 19 years and she is pretty gunky on the insideAny suggestions would be appreciated.

I would pull the valve covers first and see how bad it is. You do not want a lot of old crude deposites to break loose and run through your motor. If its all gunked up, clean it the best you can, put the valve covers back on and then do what others have suggested.
I use a quart of transmission fluid and drive it for about 3-500 miles, while monitoring temps and oil pressure.
