I’m having an issue here, this started a few weeks ago and it getting worse. At start up there’s a loud rattle then it goes away with in a few seconds, Now it’s lasting longer. I have no clue what it is or where it’s coming from.
Any help to determine what it maybe be?
Thank you in advance

If it goes away, and also isn't present when you start with a warm engine, then it is likely the timing chain. Just replaced my 2008 with a 2021, as nobody would touch it and the full engine swap was just too much vs. vehicle value.. Sucks, because that 2008, even with 219k miles was a great car.

How many miles? Has it had a timing set replacement? My 2013 had noise on start at 80k. Both tensioners had failed seals. I changed it all, followers, and added a high volume pump. No noise afterward.

I have a 2010 limited 2wd with 260,000 miles on it now and have owned it for 13 yrs. I also use 5w30 every 5,000 full synthetic oil. I said no to the current suv prices even with going to my credit union and told my wife I'm going to get everything fixed. I watched all the videos on the 5.4 that FordTechMakuloco did and went a head and called BSG Automotive (FordTechMakuloco) 181 Commercial Dr unit b, Yorkville, IL 60560 ph:630-687-1207 left a voice and sent an email about the issues i was having and what i needed fix and his recommendations.

It was the best $6,500 spent

Items replaced at 250,000 on original engine and transmission.

The following items are replaced during the service: chains, tensioners, guides, tensioner arms, VCT solenoids, phasers, Melling HV oil pump, gaskets and oil change after. two heater hoses, oil pan removal for clean out, all engine mounts, transmission mounts, coolant hoses, new water pump, new spark plugs, new rocker arm, valve lifter, follower lash adjusters.

All work was completed and done within 2 days.

Before I had all the work done I had all the u-joints replaced at local drive axel company. I did new rotors, pads and parking brake, replaced all suspension parts on the front end, inner and outer tie rods, lower and upper control arms, ball joints, sway bar links. I replaced all the rear trailing arms in the rear, lower control arms rear, rear diff drain and fill, replaced transmission pan (Dorman 265-854) with drain plug, gasket, drained and fill transmission all at home in the garage and made my oldest son help.


The truck drives like new, improved gas milage city and highway.

I did the drive from San Diego, CA to Yorkville, IL in 26 hours only took a 3 hour nap.
