Hello everyone! From this monday I'm an owner of 2006 Ford Expedition with 5,4l Triton engine. I was looking for a Chevy GMT800 Tahoe or Suburban for almost a month but I couldn't find any in an acceptable shape. Because of that I get interested in the Ford Expedition, and I was able to find one in a mint condition. It has only 99k original miles and seems to be very well maintained.
So after I've bought it and drove about 250 miles I realized that I can hear an annoying ticking sound inside the cabin. The sound reminds me a bit a sound of an old Singer sewing machine or simply a diesel injectors noise. The ticking speeds up with the engine RPMs and intensifies with the engine temperature (I can barely hear it after a cold engine startup). I have no other truck to compare with, but after 250 miles I think my truck acceleration is to weak and fuel economy is bad - I get about 12 MPG 80% hwy/20% high traffic city. There also are some DTC codes, I'm attaching them at the end of my post. There are no other issues, engine starts up fine, idles smoothly, no vibrations, no missfires. Engine oil pressure builds up immediately after startup.
At this point I must admit that I read a ton of topics similar to mine on the internet - most people would say that my cam phasers are gone. It might be, but there is one more thing: a previous owner performed a huge maintenance service about 600 miles before I bought the truck. Things that were done:
1. Timing set with a new phasers
2. Exhaust manifold gasket
3. New alternator
4. New set of spark plugs
5. New camshaft position sensor
6. I can see some new grounds wires undere the hood
7. Fresh oil and oil filter (I don't know the vishocity though, I can also see that the filter is an aftermarket one)
Previous owner told me, that a technician who worked on the engine decided to pull it out of the truck to have a better access to all components. I want to diagnose the problem properly before I start throwing money on the parts that might be good. I don't know quality of the parts they used for maintenance, and the quality of their job. The first thing I will do is to change the oil and filter. I bought Motorcraft 820-s filter and high quality 5W-30 fully synthetic oil. I'll check if spark plugs are not loose and look for any exhaust leaks. Knowing that the engine was out of the truck I also must check all electrical connectors - maybe they forget to plug in something. What else can I do to diagnose it? Do you have any suggestions? I'm a bit interested in the alternator replacement job - since it is new, maybe it produces any noise that may affect sensors on the truck? Any clues will be very helpful for me.
Regards,
MC
