My post before said that the pollution pump thing froze up and it wasn't the belt had lost a tooth or something but it was that the belt was rubbing the pulley and burning up causing smoke. Thanks for the warning about the oil screen. Also, I baby this truck reving up to 4K at most...the first run was because of a bad cable sticking and the second one was just for the hell of seeing if the engine could take it again. Wont be doing it again. The whole point of this thread was I was just asking about people taking their engines past redline...its gone way off topic now, and I am not in the mood to bash on people so later im out.
