Is there a replacement expansion plug ( freeze plug) for RB blocks that would be more reliable than those dish type welsh plugs?
I thought someone a few months ago posted something about a plug that has some kind of mechanical holder built in the plug, grabs the inside of the block like a block heater plug maybe??
I was road testing my F , one plug came off while passing a vehicle at 80mph...makes quite a big cloud of white smoke!
