I went out to my car to finally finish installing my FFIM, it had been sitting for about 5 weeks waiting on parts, prior to that drove "fine", (still working on a tune)
anyway while pulling parts for the FFIM I started to drain my radiator, what came out was "black muddy water" if it had been reddish/brown i wouldn't be worried. the bit the splashed on me dried just like mud. it didn't have an oily feel but honestly I can't think of what it would be. its an aftermarket Aluminum radiator. the engine was cleaned prior to assembly head and block were decked prepped for a 2.0 mm MHG ARP head studs. I've got maybe 10hrs total run time on the new engine between tuning and some drives around the neighborhood. I was using tap water from the outside hose until I had the engine dialed in, only thing I could think of. Every other time that I had to pull the radiator and I drained it, water would either come out rust colored or clear. this is the first time i've had this black muddy water.
Thoughts/comments thanks
