How long are you expecting to get out of the bottom end of your engine, now that you have replaced the top end? How long do you think the main seals will last, compared to the new top end? How about the bearings, and rings? Now that you have it apart, can you see how oil couldn't get into your heat exchanger from your not blown head gasket? Can you see how the valves were adjusted improperly, and inconsistently from each other? Do you also notice that the fuel injector pop pressure varied between cylinders? Isn't learning fun?
