Michigan Man, This forum is full of real mechanics that want to do nothing but help you. I truly understand your frustration, but you need to understand that we just can't spit out information on a whim. We need to truly understand your problem completely before we can advise you. Remember, you are there looking at the problem, we're not.

If you have the chain on and timed properly, and your still getting blow back through the Throttle body, you might have bent a valve. Have your mechanic check it out.
