as you all myay already know that i overheated my rex this last weekend this weekend in going to do the block weld trick. but my NEW problem i started her today and i opened my radiator cap and i see small dark black deposits in my coolant. i was able to get some out with sticking a old t-shirt in the neck and i felt it,it was clumpy, thick, and it was almost like a grease. what could this be. am i goingto have to add something to my oil too. oh and while starting it was flooded so i knkow its going to smoke like all hell for a while but she was running for about 20 minutes b4 i shut her down i dont know that is either.

thanks guys!

well the only other fluids in the engine are gas and oil, so it would seem some over heated engine sent some burnt oil in to the water jacket.
