CLASS RACER FORUM - View Single Post - Any Ford techs out there?? 5.4L questions...

I have been towing with a Lincoln Mark LT with a 5.4L (no jokes, Billy). It's got almost 80k miles on it. I have not heard of the spark plug problem but I have heard of exhaust manifolds coming away from the head. (I'm told the studs in the head are of inadequate diameter and they work themselves loose. I had this happen on the passenger side and it was successfully repaired (so far). Other than that, it pulls just fine. My race car/trailer weighs about 5500 lbs.
