No, I'm in california but have a non-ca emissions vehicle and I don't have the knock (the fuel is extra ****ty though).
Well I have nothing to do tomorrow so maybe I'll go by the dealership and pop the hood on one. It should be super obvious.
Maybe ford changed a parts supplier and the new part is making the noise.
Not sure but there have been a lot of people with Cali emissions complaining about the same thing. I would stab a guess at a belt driven air injection pump or similar because Ford says it's a normal characteristic.
They all say the knock goes away with the FEAD belt removed eliminating base engine and narrowing it to an engine accessory.

Thanking everyone for idea,s and help. My new truck is 50 states emissions for California! But,I see water- pump,alternator-left belt and a/c to rt. belt? No air pumps etc. The knock does sound like a loose piston, deep toned knock,knock,knock.Frequency increases with rpm and best heard 700 to 1500 rpm.But is there all the time!Could be torque converter? There was a old TSB 11-7-1 for FEAD belt, but does not apply I was told. I wish they had shut-off injectors,one at a time ,and listened to make sure not piston slap.
I have a 2011 Mustang with a 5.0 and a 2013 F-150 with a 5.0. I had planned on having the 2011 Mustang's oil changed before 1,000 miles, but heard of other Mustangs that exhibited knocking or ticking noises after the first oil change, typically when the first oil was change was made before 1500 miles. So, I waited until 7300 miles for the first oil change in the 2011 Mustang. I noticed no engine ticks or knocks beyond what I would consider normal (I had a 5.4 in my 2004 F-150 that sounded like a diesel, but ran fine and would easily break both rear tires loose for 20+ feet, so maybe my perspective is off a bit). The 5.0 in the Mustang burns typically just less than a quart in between 7300 mile oil change intervals, and has achieved an overall average of 27 MPG.
I decided to stick with 7300 mile oil change intervals on my 2013 F-150. I noticed no ticking or knocking after the first oil change. This 5.0 seems to burn less than 1/4 of a quart between oil changes.
I just went out to verify that both 5.0 engines are very quiet. There is a very faint ticking noise in the 2013 F-150 (with roughly 14,000 miles on the OD) on a cold engine start up and drive forward and reverse after a 5 minute warm up. I believe that the faint ticking noise is normal, just the injectors doing their normal activity. The faint ticking noise in the Mustang was even quieter (with over 34,000 miles on the OD), once again I think that it is just the injectors doing their normal thing. I typically give my vehicles just a 10 to 60 second warm up before driving away.
Did you use the correct Ford oil filter and semi-synthetic 5w20 oil for the oil change, and verify that the oil is not over or under filled? I have had all of my oil changes in the 5.0s performed at the same dealership, in one case the oil was a quart low after the change, and in another it was two quarts low (the old push rod 5.0s took 5 quarts, so there is a chance that you are down 3 quarts if you had the oil changed at a shop of some sort that used out of date oil capacity charts). There were some early reports of Mustang engine ticking apparently caused by a defective valve (weak spring?) in the oil filter close to 4 years ago, but I would think that problem would have been resolved a long time ago.
An Internet search turned up a few threads on Mustang forums that may be related to the problem that you are experiencing. The first thread suggests that a knocking sound could be attributed to a stretchy belt (I seem to recall a couple of threads where the ticking/knocking sound was caused by a faulty timing chain):

I had the dealership do the oil change at 1,200 miles. It was making the noise already.Thats why they did the oil service and inspected my oil filter for metals. Motor craft parts and oil was used.Stretchy belt TSB does not apply on 2014 because the rt belt tensioner is different,I was told. Thank-You

If it has a metal slap/knock OEM has to fix it. A belt U may have to pay for but not the labor while a water pump is warranty. You can find a piece missing from a belt! A valve tick is a bad original fit. Same with piston noises which do not go away until the motor warms up/ A rod nock / near by main bearing problem is there when the motor gets under light load. Motor does create its own problem when it is first started up if everything isn't near perfect during the build. These motors are spun not run at the engine plant.
