Hi my name is Ryan, I am 13 years old, my dad gave me his 93 ranger with a 2.3 L to work on , it has 50psi in one cyclinder, and about 100 psi in the other three, I plan to pull the head off to see what is wrong, I do not have a cliton's manual yet, wondered if you could give me some pointers, I replaced the water pump on this truck a couple of months ago, but mostly my experience is with lawn mowers and motorcycles. I would like a basic few steps to get started and what to watch out for. Thanx

FYI - the problem started after the water pump went bad and the motor was over heated. Truck still runs but it is weak.
