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.

Watch Fordtechmakuloco videos on YouTube. I don't know if to trade or fix???
My wife would love to have a new fully loaded Ford Expedition or Lincoln Navigator, but with the current car market i would rather take vacation with the family, home improvement projects. I'm a person that like to keep vehicles for long term use and the current price for these suv are ridiculous to buy over $1,100 plus a month. I can find some lease deals on them around $800 plus, then higher insurance and registration. I just fill it is a waste of my money and my family. My current truck is loaded with every option for it's time, it drives very well, towing is excellent. I had had zero problems with it since i have owned it other than the timing issue that didn't show up until about a year ago. It was a simple choice do the repair and have the expert Brian at BSG Automotive do it.

Best decision to pay $6,500 and I can keep the other $90,000 in my pockets. I can wait it out for a new suv prices to decline.

Your timing chain tensioner gaskets have failed causing too much slop in your timing chain. That slop has probably broken your plastic timing chain guides that
cause rattling on start up. The leaky tensioner gaskets also bleed off oil pressure that is needed to operate your cam phasers correctly, thereby causing hot idle rattling or knocking noise. This is the most common issue with the 5.4 3 valve engine and simply requires a replacement of the timing components to include the timing chains, tensioners, guides and cam phasers. In addition I would replace the oil pump with higher volume Melling unit plus VVT solenoids and cam roller followers to truly bulletproof the engine. Its about 1500 dollars in parts if you do it yourself and Im guessing $3000 including labor maybe more. Is it worth it? I had to do mine at 100,000 miles but the truck was otherwise in fantastic shape so yes it was worth it.

Heck yeah Brain AKA ( ForTechMakuloco) is great! I would drive to him for sure and give him my business for the 5.4. Great job bud, i am in PHX and also plan on driving out to him when the time is needed.

I bet your Expy drives like new now.
