  1. Well done! There is another case of noise being the answer, but being a Toyota mechanic you may not see it much. Exhaust leaks from one branch of the exhaust manifold can imitate a rod knock. Nissan had a lot of problems with broken exhaust manifold studs in the 1990s. The tap-tap-tap sure sounds like a rod knock, but listening to the engine block reveals that it can't be heard on the engine, only in the air. That truck sounds so much better fixed!

  2. Well since my aux belt was not supposed to be glazed, I got the spare tire out and poured sugar syrup all over it and let it dry. I don't see what all the interest in glazed donuts is about. Hmmph.
