    Check the right rear brake. If they havent recently been reaplaced it will be toast.

    One of our trucks is an 06 with the 5.4L and as of yesterday it has 60'ish K on it. The only things we've had to do to it was replace the exhaust studs and gaskets one it one time and a couple years later (last month) we had to replace both exhaust manifolds, studs and gaskets. Both times it was after towing our skid steer and some other things on the trailer long distances. We put a K&N air induction with air filter on it and a programmable chip when it was new, other than that it's been problem free and its towed or pushed snow since it was new. 5.4L's might not have a ton of power but ours has done everything we've asked it to do. I wouldn't shy away from a 5.4L, they are solid engines!

    I have the powerstroke for serious power when needed....Thumbs Up The 5.4 is going to be towing a 20' hardscape tool trailer & plowing snow in the winter. Something the 5.4 is more than capable of doing.

    like all fords watch out for the oil pans being rusty. i have a 5.4 and love it for light and medium work but have a powerstroke for the heavy lifting

    I have had 3 of the 5.4s, check the manifolds, check for the lifter tick, find out when and if the spark plugs have been changed, check the tranny lines, I would check the rear diff cover for rust. I would also check the bed mounts for rusting, also check the sway bar links and suspension!

    how old coolant?
    Have oil been changed? Motorcraft oil filter or aftermarket filter?
    Peek in oil cap with flashlight look at camshaft while it idle do you see oil splash on it?
    Check exhaust pipe if it black it been running rich need fix.
    Look harder in coolant they do had issue with oil get in coolant.
    Ask owner what oil they use? 5w20-5w30 is ok but 10-40-20W50 isn't OK.

    I will disagree with anybody over KN air filter. I wouldn't dare put that KN air filter on my fleet. I use stock purolast or motorcraft so I can know dust not going pass though air filter and get in engine ruin cylinder then it suck tons oil.

    I never have issues with exhaust manifold or studs on mine but I don't drive like employees while tow heavy load and drive across water puddles. When you have common sense don't ever drive across water puddle those will break studs quick. Learn hard way when I did with my Explorer.

    Inspect rear axle brakes. I have 2 with defective brakes cause they wasn't maintain by previous owner so it was cost fortune to fix them. They got rusted and seized.

    The lifter tick. Is that a common thing? I've heard a lot of Ford gassers tick. Is that what that is?

    So I must have no common sense and it should never be driven in the rain right? to avoid puddles of course. Funny, both times mine went bad were on dry thru-ways during the winter. To the OP.... Problem is they get too hot while basically maxing out there performance for long periods of time, they warp, stretch and crack the cheap studs. They usually break off at the manifold and IF your lucky you can still get something on them to remove the complete stud. Most of the time you end up replacing the manifold, gaskets and studs to the tune of 500-900 (or more depending where you take it and if they use OEM parts). Good news though, if you have an Advance Auto Parts store near you, you can buy a "aftermarket" manifold which seem to be nothing more than an OEM cleaned up and the surfaced shaved so everything is nice and level for 95.00 compared to Ford's 300.00 or so each! Another thing, these new 5.4L's are 4 valves per cylinder versus the older 2 or 3 valve per cylinder (its been so long I can't remember what they were) but the old style kept blowing out spark plugs through the tops of the cylinders but thats a thing of the past. I worked on these things weekly years ago and I never heard or seen oil in the coolant, not saying it never happen but I never saw it. About the only other thing we've had to do, and it is common is ball joints, if you plan on running a plow on it expect to replace them every other year. One last thing I remember is check the oil dip stick tube where it bolts to the head, when we replaced the manifold we took off the dip stick tube and where they weld the bracket to bolt it to the head rots away letting dirt right into the engine, other than that just check maintenance records and all the obvious stuff.

    Care to explain why I found THICK BROWN SLUDGE inside tank. It was common issue from early 5.4L to mid 2002 not sure exact. When they finally update head gasket issue that was LEAK on passenger side.

    It was look like this [​IMG]

    The tick could be bad manifolds or lifter problems, the cam phasers go bad causing the tick
