Yes, they are still out there NUMBER 2

[Terry,OH]

For my 34 I removed the oil pan and found one of the welsh plugs to be leaking (rusted through) so I removed all four and with the oil pan off, I put a piece of plastic over the crank area and flushed with water through the water pumps as well as the lower mounts and used wire in the rear welsh plug holes to remove build up and foundry sand. I got a couple of cups of junk out of the rear plug holes replaced the welsh plugs and assembled the clean pan.
