I have a 93 t100 v6 3vze 2wd. I have misfire and a kinda metal knocking sound from the engine. I’ve done a compression test. And changed out the spark plugs and wires. Still the same if not worst. I feel like a have messed up valves or piston ring problems. I’m thinking of maybe rebuilding the motor or swapping it out. Don’t know what would be cheaper. Any help plz.
