Re: Cold start rattle!

ZSHO · September 22, 2017, 08:21:25 AM

I will start a separate Topic on the subject on hand soon.
I unfortunately have been hearing this short one second rattle upon cold start up which has me a bit concerned.

Today was the second time this has occurred in two months and always have used Redline Full Synthetic and Amsoil signature series full synthetic oil along with the Motorcraft Fl -500s oil filter.

I have always changed my oil religiously at frequent intervals and 3K would be max for a peace of mind.
To be continued, thanks. Z

Hmmmmm it's not the typical one second rattle on start up that happens? I can't remember the name of the part ATM...

Ugh. Rattles suck, unless they are meant for babies ...

Cam phasers.... it sometimes takes a second for the oil pressure to build. Might want to check your oil level. It appears some cars make more noise than others while the oil moves up into them...

That being said, Z knows his car better than anyone, so if it's a new noise then perhaps there is something else going on. Other culprits of that noise based on forum feed back is the rear turbo.

Some have mentioned the HPFP as well during start up rattling...

I appreciate all the replys from ^^^ and only has happened twice in the past few months IIRC!
I noticed that it sounds more like a plastic rattle than a metal sound.
FWIW almost have 2k since my last oil change. Z

SHOdded · September 22, 2017, 03:48:17 PM

so MANY plastic parts on this car. bellypan, hose clamps, hpfp cover ... hopefully it is just a fastener at fault, spurred the vibration of an engine at startup. Doesnt sound like a suspension or mount component. Maybe check the direct meth system as well?

ZSHO · September 22, 2017, 04:01:22 PM

Thanks so much and will just keep my ears and eyes open and just monitor it. Z

I was getting a similar noise when using the motor craft oil filter, switched to Mobil-1, poof gone.

Might want to check to make sure your noisemaker is secure. Also any plastic parts that may have been impacted when LMS removed and reinstalled your intake manifold.

Additionally if you can get under your car I would check to make sure that the new Alky pump is still secured, along with the new reservoir that they installed.

Not uncommon for something to be slightly loose after everything settles in after being taken apart.

Just my .02 cents..

I guess sometimes its in front of you and you don't see it!!!!!
I found the front bumper a bit loose which makes perfect sense since having the DPM installed.
Does anyone know how to tighten the front bumper on the 13+SHO?
Its unfortunately getting dark here and will try to tackle it early tomorrow am or will contact LMS,Thanks. Z

May need bumper cover mounting brackets, or new fasteners. Ever since the transition to pictorial description of things in the FSM, it's a bit hard for me to tell.

ZSHO · September 22, 2017, 07:37:33 PM

-MANU Thank you so much. Z

I called a good buddy of mine to give me a hand with the front bumper and will post some pics of during the day. Z
