Will oil help...
Last year I purchased a S70 GLT that had a motor locked up. From what I knew, the PO purchased it with a bad head gasket and let it sit a few months before trying to fix it. Well, between the PO PO and the PO, the motor rusted inside and locked up.
BoxPin showed how fast the inside of the motor starts rusting when the head gasket blows and allows coolant into the block. So, I'm wondering, if I find a car that has a blown head gasket, and the motor is NOT locked up (meaning that I can turn the crank a full revolution), do you guys think I can drain the motor of all oil, fill the motor with oil (about 10 quarts or what ever it will take to fill oil into the head), then turn it over once by hand, then let it sit till I get around to doing the head gasket? I'm trying to figure out if there is a way to lube the motor with good oil so the thing doesn't rust inside and lock up.

Robert, unless you know the history of the motor, the HG might not be blowing into the cylinders...I'd pull the plugs and see. A squeaky clean cylinder means it was getting wet. I don't think I'd massively overfill the engine as you suggest. You'll hydro-lock the engine and the rods will bend long before it can be turned over ever again w/o tear down...would keep it from rusting though. I'd say a much more reasonable solution would be to pull the plugs and shoot some Marvel Mystery oil into each cylinder.
Unattended, it really doesn't take long...

Sorry, I couldn't resist! Well, here's the thing. You're pulling the plugs regardless, might as well peek in there. I have a bore scope which makes it ever so much easier but I'd still have to peek. I've been known to use a shop vac to extract standing water, blow out as much as I could and then oil it up. Just don't oil more than an ounce or so per cylinder and besure to turn it over once a month.
