I am a long time F-150 owner, but recently bought an '02 Ranger w/3.0L, 2WD, and A/T. The truck has 123,000 miles. I am using 4qts. Valvoline 5W20, and 1qt. Lucas stabilizer as lubricant. The motor is strong.
My question is: At an idle, engine makes a ticking sound. Is this normal for this motor? Also, coolant is brown. Is it normal for this to happen in this motor? I have run V8 engines my whole life, this V6 is a first for me, and I want to learn all I can. Any input will be appreciated. Thank you.

I'd flush and fill the cooling system. Brown coolant is not normal, but it could just be old.
My 3.0 has always ticked a little. It's kind of quiet though. Sounds like valvetrain and injectors clicking on/off. You can only really hear it when the hood is open. If your ticking is loud enough that you can hear it while sitting inside your truck, there may be an issue.

I would get rid of the Lucas and just use regular 5w20 with no additives. As for the coolant, it's possible someone put the wrong kind of antifreeze in there and two different chemistries mixed. The correct coolant to use is Motorcraft Premium Gold, or Zerex G-05 which is available at Napa. It is a light yellow/gold color. I would flush out the cooling system and refill with the correct antifreeze.
