    Well, I scored a set of Pacesetter headers for my '06 FX4 4.0 SOHC and I've snapped the engine oil dipstick right down by the o-ring. Luckily the whole tube came out of the block and nothing dropped into the oil pan. Anybody heard of that happening? Should I replace it with a new one or...

  7. Another alternator question

    Good morning all. Working on SWMBO's truck today. We have a 2004 Ranger 4.0. The alternator went out a couple months ago and I replaced the brushes and voltage regulator. Just the other day, it wouldn't start. Figured we left the door ajar or something and jumped it. It's done the same now...
