I blew the head gasket on my truck last year. A good deal of oil got mixed into the coolant system and some of it has adhered to the overflow and radiator cap. I assume that is the situation throughout. I have had it flushed several times, but that doesn't remove the gunk. Is there a way I could do it at home--or a serive that can remove the buildup? Thanks!

There is a radiator neutralizer by prestone I have used to flush out muddy coolant systems. The process takes hours to do. If you do it exactly the way in the directions it will work. I dont remember the exact part number but I believe the gm dealerships stock it due to the coolant issues they are having with the new coolant. Try there and let us know how you make out.
