Been a while since I posted last. The '61 Apache is pretty much wrapped up except for a few minor details. Have one recurring problem that is baffling me a bit. When I start the truck after sitting overnight I get a good amount(maybe quarter to half cup) of VERY rusty water from the tailpipe, it continues to drip a bit while the motor warms then clears up. I done the usual diligence, no oil in the radiator, no coolant in the oil pan. No exhaust smoke or pulse in the radiator with the cap off. Oil and coolant levels staying the same, at least there's no noticeable difference over the last week. The water that comes from the tailpipe has no hint of the smell of the plain old green coolant that is in the radiator. And no steam from the tailpipe. Yet, there it is every time I start this thing.(on average about three times a week)Is there something I'm missing? Would you chalk it up to just plain condensation in the muffler? Truck stays inside the shop all the time, never parked outside at night. Thanks for any ideas.
