Are you using a motorcraft oil filter that has the proper anti drain back valve if not I would get yourself a motorcraft fl-820s and six quarts of motorcraft synthetic blend from Walmart and do a change and see what you got from there. Be sure to fill the filter before installing. With out hearing it it's hard to tell if that's what you are actually experiencing though.

I have a 2003 V10, I use the 820 filter and motorcraft 5w20 synthetic blend. Are you sure the sound you're hearing isn't the vibration of the aluminum flex plate cover on the tranny? Sometimes when mine is first started there is a metal vibration sound coming from the front of the tranny. Ive poked around under there and cant find what the vibration is, but it goes away after the truck warms up anyway so I don't worry too much about it.

It's more of a tick noise. I'm using 5w-20. It goes away after 5 seconds of starting. I just can't figure out what I need to do. When it was really cold out side I would plug her in over night and start her up the next morning and the noise would be very short. Could my oil pump be going bad?

Sounds like your issue is a common one. There are many posts from owners addressing the same noise. Some say piston skirt slap, cam/follower, timing chain... It could be all the above?? Mine does it and has since I bought it 5 yrs ago with 70k on it. I have read posts where the engine has 200k on it and has made this noise for 100+k with no mechanical issues. Just alot of moving parts to oil up at startup.

I can not say if it will be the cause of failure of any given part of the mechanical workings of your drivetrain. If you are referring to the 'tick', I failed to mention exhaust manifold stud breakage. This can contribute to the 'ticking' sound. Check them for breakage. This is a very common issue with the Triton engines.

if it is coming from under the engine and not on any side like more driver side or more on passenger side then it could be bearings or pistons and in that case there is not much oil is going to do to stop the noise. when i was running rotella 15w40 i had a knock on the lower end on the motor i switched to 5w20 and still had the same noise.
i am to the point now that im going to run 5w20 and a motorcraft filter till it blows i do not have the time nor money to tear in to the bottom end of a motor that still runs.
and my truck has over 260,xxx miles and the knock goes away after a minute or so.
which use to worry me but now as long as it goes away im good.
these engines make alot of noise and it seems from what i have read on here that is just how they are

You could send a sample of your used oil off for analysis. This will be a good way to tell if you have something wearing excessively in the engine.(higher than normal levels)
On a cold start piston slap is fairly common for a short period of time. hypereutectic pistons with a short skirt coupled with a rather long stroke tends to produce some slap until the pistons get some heat in them. If you have a minor exhaust leak at the manifold, y-pipe, etc you can get some ticking until it warms up
I'd just keep running a quality name brand 5w-30 oil (blend or synth) and a Motorcraft oil filter.

My long gone '90 with a 300 six would tick for a few seconds with the Ford recommended oil, 5w30 if I remember correctly. Changed to a 10w40 and cut the ticking time in half. Then changed to a good full synthetic 10w30 (maybe 10w40, do not remember) and eliminated the ticking. This was back around 1991 with about 30,000 on the truck. Loved that old 300 six!
Used a good full synthetic in my 2000 V10 after break in. Changed oil every 10k and Pure 1 filter every 5 k and never had any engine problem. Sold that truck with only 134,000 on it.
