My dipstick will not read any oil........when I put my engine back together, I put 2 full quarts in(which I knew was too much). So I used the oil check bolt on the case, and drained about a half of a quart out. What is up with that? Also, when I accelerate, I can hear a whistle, almost like a turbo spooling up. When I let off, it goes away. Are these normal issues??
