[QUOTE="integritymechanicsbydavid, post: 1567044, member: 38890"] Heard something new today. Cold start and tiny bump bump noise coming from intake box. I’m starting to lean towards a sticky valve. Gonna take the valve covers off Sunday and look at rockers and bridges then do a compression test on all cylinders. While I’m there I’m replacing both injector harnesses. Might as well replace the pressure sensor. I’ll also be adding 60oz Hot Shots Secret Stiction Eliminator. The heads were done 60,000 miles ago and still look new. I’m not going to be happy if it’s a failure. [/QUOTE]
