Well the timing belt was broken. Its all fixed now and the truck is actually running well. I expected it to have to have a head job. There is no power loss and its driving just like it did before. The only thing different is a barely audible click in one of the valves. I expect it to get worse, but so far so good. The only question i have is when i go into 4 high and then go back into 2 high I dont have the same acceleration anymore. Its slow, but if I go rom 2 high to 4 low and back nothing changes. Anyone with an answer? Is my timing slightly off maybe?

You probably do have a bent valve. The tick will be the cam follower tapping on a now too wide gap between the rocker carm and valve tappet. Check compresson on the ticking cylinder, you'll probably find it to be low.
