    Default M60 pumping out rust fountain?

    Definitely a red looking fountain shooting out of the expansion tank when revving it up. So I am guessing the only rust available on these engines would be water pump or head gaskets. What else would cause a rusty coolant? It's not a different color coolant it IS rust!

    I also think the head gaskets could have rusted through or possibly a missing thermostat, OR the bleeder that was partially clogged is causing cavitation causing the fountain on rev ups?

    Anyways I pulled the hacked up radiator and JB welded the leaks and will wait a bit to finish that part up to confirm if the engine is good or has a head gasket issue. Anything else I should be looking out for at this point? Not going to be dumping a ton into this thing until I have an idea if the engine is good. No oil in rad and and no water in the oil. No white on the oil filler cap either and no steam in exhaust.

    Working on this 540 is a bit of a challenge since my main driveway spot is still taken up by the E46 that I wanted to sell last year... Another story for another time.

    Any help appreciated as always.
