2007 Lincoln Navigator Turn signal relay location?
It doesn't have one Controlled by smart junction box .
The smart junction box (SJB) monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is pressed, that input signal is routed to ground.
When the SJB receives a request for a turn signal or hazard lamps, the SJB supplies voltage to the appropriate turn lamps.
The timed on/off cycle is determined by the SJB and is set to flash approximately 80 times per minute if both the front and rear turn lamps operate correctly. If an individual turn signal lamp is inoperative, the SJB flashes the remaining turn lamp approximately 160 times per minute.

Lifter replacement 5.4L
I must mention that engines with the DOHC emblem had a problem with "Cam Phasers". These would rattle and knock very similar to a Diesel and the noise would fade at about 2000RPM.
This engine has 2 timing chains. Since the Camshafts are on top, the lifters are under the cam. You would need to remove the cam to access the lifters. You will need to keep the cam gear positioned or lose the mark. There are cheater tools which allow you to sneak the cam gear away from the head to change the Cam phasers.
The cam phasers can then be removed. This is perhaps as much as you need done. I retired before this style of engine was built, so I can not tell you if the Camshafts can slide forward to be removed once you remove the Phasers and gear. Otherwise you are looking at a full frontal disassembly, just the Cam Phasers alone required full frontal disassembly in the original Service Manual.
You can read more about this engine and find Videos on the Web. I have an Engineering print but an assembled engine may have clearance issues. Wish I could be of more help, but you can get quite a rattle from the Phaser issues. Don't blame the wrong part.

This is saying your gascap is not on tight or there is a leak in the tubing for the Emissions system.
If tightening the cap does not help, then a device called a "smoke machine" must be hooked up to your car to find the leak. You would need to call to find a service place possessing such a machine. Then it is a simple matter of fixing the leak.
