Head gaskits on a 85 ford 6.9 idi

Im not familiar with the 6.9L IDI, but white smoke is also unburned fuel also, or a sign of leaking antifreeze I would see if you exhaust smells sweet or if it smelled like raw diesel. Now if you have oil coming out of the exhaust it could mean you have a worn cylinder, cracked head, bad valve. ECT, ECT. Best place to start is to perform a cylinder compression test, see which side has low compression and tackle that side. If its a blown head gasket simply remove head, clean block and head, and inspect the head and move on with life. If you have a cracked head then well.. You need a new head, and head gasket. But if you have low compression in a cylinder, when you do the compression test see if you can see oil or any containments or damage in the cylinder. Hope that I was some of assistance.

its a 6.9 and it most likley just hasnt been driven enough to remove the moisture from the oil, short trips and such will do that ...
