1985 F250 6.9 Auto ATS Turbo Oil LEak

:)
This is a 1985 F250 6.9L, auto, Ast aftermarket turbo with 135000 miles. Does anyone think a minor oil leak on the driveway can come from a headgasket? A mechanic told my relative that this minor oil leak (size of a tennis ball) is coming from the head gasket. the truck requires no oil between oil changes. T thought when a head gasket leaks, it leaks collant. The collant on this truck never needs to be refilled. Any idea where these 6.9s typically leaked? And if this minor oil leak could be coming from the Head gasket, will it get worse?
Thanks

could the turbo, or where its connected be leaking a bit of oil, I dont see how the head would be.

I be more inclined to look at front seal and also the rear seal as being the source of the leaks. My '83 F250 ( with a 460 ) has always been a leaker at these points. Just enough to keep every thing 'gooie'.
