This should be easy to figure out. Stick a pencil or the like up
through drain plug hole and I will bet you you find pan it loaded up
with sludge blocking drain hole. That engine is old enough together
with the quality of oil back then if it was not changed often that
some serious sludge could be built up in there. I would not try to
flush it as that much sludge could damage motor is broken loose. If it
is sludged up, the best fix would be to drop the pan and clean it out
if you plan to keep vehical for a while yet.

That's interesting. It had never occurred to me that it might be crud
blocking the hole. I'll check next time.
The truck belonged to CalTrans for most of its life, and I assume it got good
treatment as far as the running gear goes. The body is beat to hell, but who
cares? We bought it in 1998 with 8,000 miles on the odometer. Not a clue
about how many times it had gone around.
We also have a 1968 Dodge van with the same engine, which drains "normally".
I had that experience many years ago. I had bought a well used 6 cyl
flat head Chysler and when I removed the oil pan plug nothing came out
untl ran a screwdrive inot the hole to open it up. My next chore was
to remove the pan and clean it out.
That's what I planned on doing. This morning I opened the drain plug and the
dirty oil flowed out quickly and smoothly just like it does with normal cars.
First time sincd we bought it in 1999.
Makes no sense at all. Witchcraft? Gypsy curse expired?
