Believe it or not, I ended up just flushing my original extensively. It was the only option I had. As my engine builder suggested, I just used a good old fashioned garden hose and flushed it back and forth about 15-20 times with degreaser. I also changed the oil about 7 times within the first 1000 miles to be extra sure. Might have been a little overkill but what's an extra couple hundred dollars after spending 8 grand on a motor. Better safe than sorry. Hope that helps
