I did not take / make the time & effort to get all the rusty flakes out of my intake manifold before reinstalling it and doing the initial start up of my recently rebuilt 272...
well, now I've pulled the heads off to replace the freeze plugs and while its off, I'm trying to grind off/smooth off the casting flashing on the outside of the intake manifold... and wondering the best way to clean up the inside of it...
suggestions please...
also, when I get the engine back together, what can I do to "flush out" the water passages in the rest of the motor? could I simply run a garden hose in the top radiator hose and leave the bottom radiator hose off the radiator and let the water run out on the ground for a while till the water looks clear while the motor is running?
