New TSB for 3.5 GDI Sartup Rattle 15-0131

[Woody]

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.

My MKS is a 2012 with 65k.  It already had the 6/100 certified used warranty and I bumped it up to 7/125.  I see people saying it should be covered under emissions warranty though.

They are killing me.  They told me they are waiting on the chain and will have my car another weekend (it will be 2 weeks Tuesday)  In the next breath he says "The H&R lowering springs made it look really great."  Yeah, thanks for telling me after telling me I won't see it for another 4+ days.

Sorry

Seems that Ford is doing worse than usual for parts.  My car has been down for 12 days waiting on the HPFP gasket in order to fix a monumental leak in the valve covers.  My wife, who works at the dealer, had Lincoln get involved and somehow they were able to get a gasket in a couple of days instead of the 6/22 date Ford provided.

How they can be out of a simple gasket that has been used since 2010 on every transverse 3.5EB is beyond me.

Are you in a dealer provided rental?  That usually spurs them to action much quicker.

So I am out of town for the summer, and my rental ended up being a 2016 Taurus SEL V6.

I realize it is not the EB but, like the 2011 SHO I test drove, it is quiet on startup, and is much quieter and smoother sounding during idle than my 15 SHO.

I really believe this is a loose timing chain issue. For mine, the startup noise also translates to a much more CHK CHK CHK sound at idle than those without the issue I have driven. That sound isn't offensive necessarily, but is coming from the same area of the engine as the startup noise. At idle, I would describe it as a very muted version of the noise in the videos in this thread - so I believe it to have the same root cause.

The mystery to me is whether Ford will end up calling this a "normal operating characteristic," given is has no affect on performance. So Woody's results interest me. When I get back in the fall, I might make an appointment with my dealer and give it a shot .... depending on what transpires here in the meantime.

I think what your hearing in the sho is the direct injection fuel pump on top of the front valve cover. It has a very distinctive tick sound.
The non ecoboost is a sequential multi port.

 

[John Miller]

Except that the 2011 SHO I drove didn't have the noise to which I refer.  Or maybe I am hearing the DI, and it is just louder on my car than the one I test drove.

Who knows.  I know it is hard to diagnose noises on the internet.  But, if I was a bettin' man, I'd put $ that the start-up noise, if fixed, would quiet down my normal idle as well.

Very likely the rental is well-maintained and/or has the OEM oil/filter in it.  The 3.5 is pretty quiet in the cabin, not so much once you open the hood and take the cover off

Yeah.  My dealer is good about the loaners.  I have extended warranty.  I am in a 2016 MKX AWD.  Not an ecoboost, but I really enjoy this vehicle.  Doesn't seem to be spurring them on at all.  My car will be gone 2 weeks on Tuesday.  But I am having a lot of other work done and the bill is pretty high.  It's going to be like a new car.   Plugs, new chain, H&R's, full detailing, front brakes, coolant and rear diff fluids.  Tempted to do a tune with all this stuff touched up.

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?

I had the split second ticking on startup, no CEL but definately ticking that went away quickly. I know this thread has both examples and the suggested oil/filter combo helped my issue as indicated in earlier pages.

I find when it is warm/hot outside it'll rattle REALLY loud but when its cool/cold it barely rattles at start up. Can someone explain why that is?

 

[SHOdded]

Is this observation based on fresh oil, midlife oil, or endoflife oil? Could be viscosity changes, could be parts expansion (ie, timing chain tensioner) in hotter weather, OTTOMH ...

I got about 1000 miles so far with my motorcraft filter and aimsoil.

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

I thought the rattle sound we were hearing was the tensioner ratcheting out when the oil pressure increases.
Not the actual chain slapping around.
It's probably a combo of both.

 

[SHOdded]

IDK, trying to ascertain whether this sound when warm/hot is related to oil at all or not.

 

[93Cobra]

The clicking you hear is from the cam phasers. These don't seem to last very long. F150 folks are feeling the brunt of this right now.

 

[ajpturbo]

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

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.

[John Miller]

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.
