Hey, I've got this horrible ticking noise in the engine that is very inconsistant. It started w/ just doing it after 20minutes or more at a sustained speed on the freeway when I got off the freeway, it would start making the noise at around 2700rpm and as I reved down down. You can hear it really good at Idle. I've tried all accessory belts, and they aren't making the noise. I've tried devarnishing the engine w/ "GUNK" and changing the oil immediatelly, but it produced no results. If, when it's making the noise, I shut off the engine for a hot second, and turn it back on, the truck runs fine thereafter. Another symptom is that is sounds a little like a diesel at idle from the inside of the truck. I read on the net that this is due to a worn out timing belt tensioner. Any help is greatly appreciated.
