Question: engine not running right

the truck runs very rough and has a extrem lack of power it back fires ocationally and also losses oil pressure after about 6 min. and this started after one of the timing gears jumped a link on the chain becouse of a bad tenstioner but that is fixed and after a long perioud of driving it i here a tick so i think it could be a colapsed lifter except for the fact that the tick gose away during the six mins i have oil pressure so. i think its one of the two what do you think? thanks

What is low oil pressure? 10psi? 0psi? If it is less than 10psi, I would suspect a weak oil pump or an internal mechanical failure of the engine (worn bearings possibly).

You need to diagnose why the oil pressure is low and go from there. It could be the engine is just worn out or damaged from the timing issue and there isn't much that can be done other than replacement or rebuilding of the engine.
