New TSB for 3.5 GDI Sartup Rattle 15-0131

[FoMoCoSHO]

Here is a video I took of mine the day I took it to the dealer.  Sounds like the same noise as the F150's, just not as extreme.

Hmm, mine has a much more "metallic" sound to it.

my engine light went off so I tried to get it inspected and find out I have 4-5 not ready's. The car seems to run fine I don't get it in fact my chain rattle seems much quieter after my last oil change and I just turned 100K miles.....

You need to drive the car and also let it cool down and heat up too

Anyone try BG products and had success getting rid of the start up rattle? Im using Amsoil and the rattle is pretty bad.

And by the way mine sounds exactly like the posted video. What year is your Lincoln? Hopefully mine is under the same warranty.

Some people think its oil related...i dont....its just the inherent design of the late ford engines going back at least to the triton series

In so many cases i'v seen the oil dipstick loose and oil erupting like a volcano and all over the front valve cover which many members have lost a couple or more quarts of oil and not realizing it due to worn out gaskets on the dipstick right under the handle and two small rubber gaskets are needed for a tight secure fit.  Z

Mine is about the same duration, but far, far less pronounced than in that video.  Frankly, I am really unsure if it is the same thing or not, but interested in Woody's results with the dealer fix. 

EDIT:  Mine sounds more like the car in these videos:

I think oil can affect it... Like quieting valves with the old STP.... But I agree it's a design flaw ultimately.... I do wonder if the increased amount of hard acceleration the 3.5 EB is subjected to (and I'm guilty) contribute to the rattle by taxing the spring on the chain tension era or stretching the chain... I don't seem to have the noise from either of the last two vids or any startup rattle.... I'll hate it if it develops.

I suppose you could find a full synthetic oil with boron in it (since the boron clings to metallic surfaces) to help reduce the chances of a startup rattle also.  I don't think the lubrication system is active before you crank the engine.

I did notice if you let the engine crank a few seconds before starting the rattle is not present.

How do you do that... I push the start button and the car takes over... What's your trick?

[SHOdded]

Keep the gas pedal pressed to the floor when starting.  Probably still cuts off the injectors ...

[glock-coma]

Yes. Floor the gas and push the start button with foot on the brake.
It will keep cranking until you release the gas pedal.

Made the Amsoil/Ford filter change at begining of May and all is still quiet every morning when starting.

Are you sure you were experiencing the same thing presented in any of the three videos from prior posts in this thread?
