Timing chain problems?

Timing chain problems?
My 04 started making a "tick" last winter and never gone away. It is more noticeable on start up and gets less noticeable after warm up, but is still there. Also, I have noticed less power and a slight drop in MPG.
I ran 1/4 bottle of sea foam for about 200 miles and changed the oil, in hopes it was a gummed up injector, but no luck
I have read some thing on the timing chains, guides can be an issue, does this sound like my problem? Is there FIX or would I be putting the same inferior parts back in?
O, tick started at 140k

well, for what its worth, my 03 makes a similar noise to that explorer on cold starts, but not nearly as bad or loud.
I dont remember my 02 being that bad either, but it did make a ton on noise between 2.5-3k rpm's.
anyone know that the motorcraft part numbers are for these chain tensioners ?

Well I just put them in today. 3 hour job my A S S.
I started at 3, finished, changed my oil, greased the front end, rotated the tires, adjusted the rear brakes and washed the truck. it in now 5:50.
SIMPLE job. The hardest part is getting to the drivers side top side one.
I still have some noise under the drivers valve cover. I am going to have to pull it and see If I see something out of the ordinary

Pulled valve cover the other day.
Started engine and listened with pry bar.
TICK was coming from front cam bearing.
I figured the lash tensioner was not "pumping" up, so I ordered 6 new ones.
Today while changing them, Spinning engine overI noticed my problem .#1 cam lobe was failing
I orded a cam and 6 new rockers.
My problem is now, how do I go about timing it? Do I HAVE to pull the front cover?
Or can I do it with just the valve cover off?
