2010 Tensioner Question

My 2010 Expy stranded me with what is probably a leaking transmission cooler line. Its got 150,000 miles. It runs good and doesn't burn oil. The bigger question is my new noise on the left side of the engine between the crankshaft and cam shaft. If I had to guess, it sounds like a chain slapping the side of the cover. I've only had this for about 20 months, but put 25,000 miles on it.
Since the vehicle is waiting for the tranny work about 300 miles from home, my options are limited. If I were at home, I'd know what to do. Trailering it back home with my 2012 5.0 with the 3.31 rear end is not viable.

Question: Repair or repower?

My thought: Good compression check and good oil pressure at idle - repair
Low compression check - Repower
If you repair factory Ford parts are critical for longivity.
Use a Melling oil pump if you replace the oil pump.

Are you concerned that the F150 would not pull the expedition home on a trailer?

it looks like you should have between 7900-8100 lbs towing capacity, assuming you have any kind of towing package.

the expedition will Weigh about 6,000, plus the trailer gets you right around the 8,000 mark. Vehicles on car trailers pull fairly easy compared to a camper.

if it was a concern about vehicle ability, I would consider it a viable option. It is one I would tackle with judicial caution.

Thanks for your responses. The problem with repair is the vehicle is in the middle of Pennsylvania, near Bellfonte, unless somebody knows somebody. The F150 has 6,800 pound tow limit (from memory). But with the 3.31 rear end it jumps all the way down to third gear. That's why I bought the Expy. I've got some time to figure this out.

My expedition with 3.73 gears jumps down to 3rd gear quite a bit as well.

i wouldn’t let that stop you. The 5.0 makes it’s power higher in the band than the 5.4 even, so rpm is the name of the game.

i think If you took it easy and didn’t try to make the trip in record time you’d be just fine if you can find a trailer. The f150 is up to the task IMO.

Good advice. Lets see how it unfolds. Tranny first, and I think its just the cooling lines, not the tranny. Parked it night before, no puddle. Only drove it about a mile to get gas. About 15 minutes later, I came out and noticed small river of tranny fluid. The source appears forward or above the skid plate. Fingers crossed. Tranny guy is slammed, Might be mid-September before I hear.

Transmission lines on those are a coming failure point. Anything with the 6r80 is prone to the same problem.

Here is an update. It wasn't transmission fluid. It was coolant from the water pump. I had been having temperature excursions to the red line on the temperature gauge while in traffic. Fans would kick on and temperature would drop back to normal. Looked under the hood and found no leaking or busted hoses, no evidence of escaped coolant and the coolant reservoir looked good. Still seemed to run the way it should, until the coolant escaped from the water pump. However, there was a noticeable sound of a chain slapping slapping on the left bank between the crankshaft and the left camshaft. Its 300 miles from home, I'm already out about $600 for towing and extra lodging. Towing it home would be another $600 plus two days of driving. Then I'd still have to fix the water pump and dig into the cam chain issue. And did the over temping cook something else?

So, I'm going to repower with an engine from Jaspers. Pricey, but it gives the peace of mind I require to keep rolling between NW Ohio and Rhode Island. This is my Mad Max traveling machine I would use more than my other rides. This is only the third time I've been stranded. First time I t-boned a Mustang II with my Father's 1972 Plymouth Sport Fury station wagon with the 400 CID, 70 mph in sleet and snow while on the interstate. He took it pretty well.
