I just finished breaking in my fresh rebuild 396. What should the oil look like after break in? It looks kind of grey. I put a magnet in the oil and didn't have any metal to stick to the magnet. Is all this goopy looking stuff from the moly lube and assembly lube? Can someone describe to me what there oil looked like when you first change it after a rebuild? Everything went almost as planned on the break in, except I started the car about 3 times, (20 seconds or less each time) to find out that my new Edelbrock fuel pump was not working. New pump on and varooom....for about 15 mins. Set timing again, adjusted the carb to get it to idle and then road test for 5 miles and then parked it. I kept the RPM down below 3800 and it ran great, no misses or stumbles. I was just concerned at how the oil look when I changed it.
