Are 616's/617's sand cast? I can imagine how that sand would be coming out of the block now that our engines are 25-30 years old. Scary stuff.
Another thing that blows my mind is how the o-ring on a spin-on filter will withstand the pressure and heat in a cooling system.
I saw a coolant thermostat designed to fit in the thermostat housing on our engines, now that I need to show you guys I can't find it
