Cold start rattle - timing chain / phasers

[AJP turbo]

Used to be the mfr's would suggest running a heavier weight oil in summertime and a lighter oil in wintertime, for appropriate startup characteristics.  Now it's the same oil year round.  Oils and their performance characteristics have improved greatly over time, partly reflected in the SAE ratings.  So I would take the mfr's guidance seriously for year-round performance.  If you consider changing to another oil/weight, compare the characteristics to make sure that your new oil will meet or exceed the requirements, the "meets xxxx specs" being a starting point. 

Although this is not as much of an issue anymore, in the past, when dino spec'd oil was the norm, people started using a full synth (usually Mobil 1) of the same weight.  Unfortunately, the full-synth oil did not really behave even close to what the dino oil was expected to, and proved too thin for practical use (outside engine tolerances), causing oil leaks through seals.  So if you were supposed to use 5W30 dino, you would have to use 5W40 full synth for comparable performance inside the engine.

Shodded dont be that guy...if you are older than 60 ill give u a pass for being ignorant..tye guys that said you cant use synthetic because they cause leaks were stupid...if your car has leaks it will always leak..synthetics are more true to their viscosity ratings than non synthetic...so its kinda the opposite of what u said...non synthetics shear quickly so if u need 30 weight before long it will have sheared to less than that so more frequent oil changes may be required with crap oil

Anybody ever heard of Alisyn synthetics?

Straight less than zero weight oil...

No i havent...seems gimiky....where is the total base number...thats the good stuff...

I read on a different page it is claimed to be group IV, 100% PAO.

[AJP turbo]

Then i would say its good stuff lol..i like group iv oil

Did we ever figure out how to get rid of the rattle? Mine is quite loud and I just recently replaced the tensioner and belt (didn't change the noise). Im also changing the oil to AIMSOIL tomorrow to see if that will fix the issue. I'll try to take a video of the sound and post it here.

There is no timing belt..its a chain...your serp belt and tensioner will have no effect....the timing chain may be stretched

[SHOdded]

Yeah, it may be timing chain stretch.

[salsathe4th]

Yeah, it may be timing chain stretch.

Thanks for the info! Worth it to get one changed?

[SHOdded]

Wait till you run the Amsoil through.  If that doesn't do it, go for the timing chain.

Here's my start up rattle.
I'm wondering if it is the cam phasers, like was diagnosed in the F150's...

mine sounds the same as yours, sometimes even louder and longer

I would just make CERTAIN you use the Motorcraft FL-500S oil Filter to ensure the proper oil flow and here's a good video on the Chain tensioner and using the proper oil filter.  Z         https://www.youtube.com/watch?v=gwliuNGflV4

So I got 5w-30 AIMSOIL however my cars oil cap says 5w-20. Should I return the AIMSOIL and get 5w-20 instead or does it not matter? My car is a 2010 mks

Good question.... FMC changed the recs to 5w30 for '13+ ....

[salsathe4th]

Ill just go to the store and swap it out. No need to risk it

[AJP turbo]

That goss' garage video is crap lol....i hate people that advise against aftermarket alternatives....he states going oem is the best way to go...motorcraft products are middle of the road at best...Z as anal as you are about care and  maintenance im surprised you use that filter

Amsoil still shows 5w-20 for the older ecoboost...which tells me ford still uses that for those engines...amsoil is really good at updating their product recommendations to reflect what the OEM says for liability reasons
