New TSB for 3.5 GDI Sartup Rattle 15-0131

[AJP turbo]

Man those f150's are junk...id get rid of them

How does the rattle respond to RPM, and how long does it last?  The belt tensioner might be worth looking into also.

The belt tensioner is near brand new. Its definitely a metal on metal rattle. Ill try to get a video of it tomorrow morning before work.

Yep, that's pretty close to mine. Seems extra common, which is extra special.

Yes - time for the chains AND cam phasers. The TSB is actually replacing both items for this problem. A new cam phaser design was implemented mid-2015, so need to watch which parts are used.

Are the parts for the SHO/MKS and F150 interchangeable?  Which TSB are you referring to, 93Cobra?

EDIT:  This one?

I also want to know what TSB.  I thought there was a TSB for the F150s, but nothing for the SHO/MKS and that those SHOs getting the fix were "one offs."

There is no TSB for my vin/year.

Actually, TSB 16-0027 supercedes it. This is what will take affect when you bring a cold start rattler ecoboost.

Do you have the PDF handy?  Heres a howto from the f150 forum

Got it!

Only change is to update labor time standards.  9 hrs or so.

That TSB is for the F150.  The dealer may or may not take it seriously if you print it out and tell them to apply it to your SHO.  What am I missing?

You are not missing anything and they will likely not take you seriously.

Is that list of parts the same for a Flex 3.5? Have to go at it myself I guess

Mine goes in in the morning for a diagnosis.

MrsFoMoCoSHO is aware of the F-150 TSB and after listening to vids I can't tell if it is the same noise or not.

The car has had the VCT solenoid and the pigtail replaced already.

I will report back with their findings.

Guess I gotta go detune.

The parts do not cross over AFAIK, at best you can see if the revision numbers have been updated.  But it's possible the part numbers are diff for F150 vs SHO/Flex/X/MKS while the actual part is the same.
