Hello all, I'm a new member. Name is Robert Boone. Most I know call me Bob which is fine with me. So I am in the process of acquiring a 2008 Ranger 4 cylinder auto with 180k miles. It's a fleet vehicle from where my brother works. He is giving it to me. He said it has a weak cylinder. Dealer told him 70% down on power in that particular cylinder in question. Told him they believe it to be a bad valve. The truck has been driven daily even with the "valve" issue. Doesn't seem to be blowing any blue smoke which would indicate a poor sealing piston, I believe. So maybe it is a valve? Im no mechanic by trade but I have been able to do most of my own engine work (not that much) and would appreciate some input specifically from those that have had similar situation(s) or are familiar with it. Should I just pull the head and go through all (16) valves or just do bare minimum? I'm going to be using the truck as a daily driver. My brother said he has driven it and he thinks its not that bad. Can notice the power is just a little off. But it was being driven daily for his company and up some of the steepest longest grades in So Cal. I may be able to just drive it for awhile and not be concerned but if I can't and have to repair it I need a little advice. I guess a "what would you do" advice. Thanks in advance. BTW the truck really looks good. Well taken care of.
