Rootes 1725 Cooling issue

Think you need a new radiator? probably not, these engines (and the 1500/1600) suffer from poor cooling, pre ignition in NO 4 due to local overheating due to sand/silt build up in back of block. Clean it out!

Good demonstration.. Had to do that recently on a 1965 cast 1725, reckon I got a shovel full of crud out of it. We also took a pineappling on the head work too $$$$..

I suspect my 1500cc Avenger motor might benefit from same. Thanks.

Where can I get spare parts for frost plugs ?
