You can drain your engine of water thru this type of plug....

[cudabob496]

When they've been in there for a while, and you unscrew them, water may not initially drain out because corrosion products have built up in the bottom of the engine coolant passages.  If you dig in there a little with a small screw driver, the rust will break up and the water come pooring out.

That is why when you rebuild an engine you need to take all of the plugs out of the engine.  There might of even been all of this in the engine when it came from the factory.  Sand and rust will be in there.

OK, - thanx..
But I got all the antifreezeplugs out of it, and try to get a little space in there for water...

It.s my 1959 383cui, and it's all filled up with "stuff"....

Was a 383 made that early?? I believe that 361's were made around that time....

In 59, you could get the 383cui. as a B-Block, (Dodge-DeSoto) - and as a RB-block (Chrysler-Imperial)..
