Yea, I recently worked on a 2014 E350 van with a 5.4 engine. Had belt squeak and noisy bearings in the idler and I replaced the belt, tensioner and idler. All work was done from the bottom on the belt problem. Good luck even seeing the problems from up top. I hate working on any vans designed like that. If I do accept the job, I charge extra labor. There is typically blood shed.If you think the f150 engine bay is bad take a gander at the vans! It’s so small under the hood it’s practically worthless to even pop the hood. The dog house is awesome and makes accessing the back of the engine super easy. But for front accessory drive stuff it seems working from the bottom is easier.
Your so right tho the 5.4 dual overhead cam design is just a monster in size. Takes up so much space and is such a turd of a motor.
I wanted to turn the work down but is a church van and my former neighbor is an assistant pastor there and recommended me.
