ALOT of people use 50% kerosene /deisel fuel mixed with 50% oil. There is of course variations to this. Here is the BAD news...

This is NOT a good idea at all. Doing this can break big sludge apart in the head and end up clogging the return ports for the oil to drain back into the oil pan.
If you do decide to do something like this, be sure to pull the valve cover too and ensure that no big chunks are there to dislodge and block return ports. Also make sure you keep an eye on oil pressure.
As for how long to run the engine with the solution it it, well I dont know. I'd surmise that u want the engine warm when you drain and put this solution in, then run it for 5-10 minutes while its hot and then change oil. Idealy another oil change withing several hours would be advised as the first draining is not going to get rid of all of the kerosene, deisel. Dont foget after the flush to change the filter as well, as it will probably be pretty much toast and the oil pump screen will probably need cleaned as well..

On my 4.3l s-10 motor, I took the intake off, the oil pain, the valve covers and removed all the sludge I could by hand, then I used about 10 cans of carb cleaner to flush the sludge down into the oil pan and did the same to the bottom of the block, then I let it sit for a day to dry out, then I rfuilled it up and everything was good.

Take this advise as a guide, not instructions. I wont be liable for anything and use common sense. I'm sure others can also gie you better details about this procedure, as I have neveractually done it. The idea of running diluted oil in any engine just bothers me...
