Did you ever figure out the ticking or ? Wondering if it was a valve, and how difficult it is. I called around and Im not happy with what people are saying about valve adjustment. Called 5 mechanics, 3 said they wouldnt do it, 1 told me to drive it til it blows, the other said around $2000.. Unbelievable. Its getting lounder and louder. What a real bummer. Anyone know any good Toy mechanics around Akron/Cleveland Ohio area? I think I may need a miracle.. I would kill me to sell my truck. Hail Mary.
