Have until Sept 30th. .

Awesome thanks! I think its the same promo I used about 6 months ago. With an OEM filter the oil changes comes out to just over $30!

From Mustang week, fast forward to about 1:40 and they are discussing a possible way to address. Haven't seen anything else on this so just a possibility.

I've read it could have something to do with the crank hitting the windage tray?

Possible cause but not the case here.

Just a possibility?
Coyotes have had the issue for awhile now.
Many makes and models have the same challenges for decades.
Riddle me this... how long in length is the gen 3 timing chain?

I'm currently running the Pennzoil Ultra Platinum 5w-20 since 5k miles. Got nice rebates from Amazon on it too like above.

Absolutely fantastic oil. I had more of a ticking noise with the stock oil that was in the car when it was cold and very noticeable in a parking garge. I don't really hear anything now. I had my windows down this morning and it was about 64 degrees outside. Pure cold start and low rpm, not hearing much. The engine runs quite well on this and I think I'll continue to use it.

I'm 90% sure the tapping noise is piston slap. Here it is about a minute after a cold start :



I went out and started a few 5.0s , not all did it, but I suspect thats because they werent broken in or were already warm possibly. A couple did do it but not as loud as mine.

From a thread I found while looking up piston slap

"Here is what a GM engineer told me on this subject..

Are you talking about piston slap during the first few minutes of warmup..??


If so...that is what it is. Nothing to fear or nothing really wrong...just the piston noise until the piston warms up to fill the clearance to the bore.

Pistons rock as they cross TDC where the thrust load from the rod angularity shifts from one side to the other. This makes noise. Harmless..but it is the source of piston slap in most all situations.

To prevent this, pistons are designed with long, tapered, flexible skirts so that they can be fitted very tight in the bores when the bore and piston is cold. The taper of the skirt and flexibility of the skirt then prevents scuffing when the piston is hot. Also, the piston pin in OEM production pistons is always offset to one side....it is NOT in the middle of the piston. By offsetting the pin in the piston, artificial thrust load is created to control the piston "rocking" as it crosses over TDC.

Unfortunately, all of the above control techniques, common in past model engines to the extreme, create excess piston mass, cause friction and cost power and fuel economy. With the desire to build in as much power and free-revving capability and to improve fuel economy as much as possible thru friction reduction these design features are pushed in the other direction on modern engines.

Piston pin offset has been reduced over the years to a bare minimum today to reduce the thrust load generated and reduce friction. Pistons have been lightened up considerably by shortening the skirts. This creates less rotating/reciprocating mass which is good for power, free revving capability and fuel economy. Light weight pistons are great but the skirts, by necessity, are short making it hard to make them both strong and flexible and the shorter ckirts make them more prone to rocking.

Unfortunately, when the performance and fuel economy oriented pistons are run cold they are very prone to "slap" until they warm up to operating temperature.

The piston designers and development engineers are always treading the fine line between piston slap cold and friction and power/fuel economy loss when the engine is warm.

It is possible that you are hearing piston noise from an engine that is on the "high limit" for piston clearance so that it makes some noise cold. The good news is that the condition is harmless and that engine is probably a little more powerful (due to less friction) than a "quiet" counterpart. The bad news is that...it makes noise cold.

As an example of what the piston pin offset can do, it was common back in the early 70's to turn the pistons around "backwards" in the large displacement Chrysler engines to gain power. Those engines had large piston pin offsets to create thrust load to control the piston slap. So much thrust load and friction was created that just turning the pistons around in the bores was often good for 10 HP. The engines were very quiet with the pistons in correctly and they slapped like crazy, especially when cold, with the pistons reversed so as to reverse the pin offset.

Racing engines do not have the pin offset and thus the pistons slap like mad...but no one hears them over the open headers...LOL.

The noise is an annoyance but will not hurt anything and the engine is fine.

I don't remember if that engine had full floating pins or not but they can also cause some ticking just after start. Same sort of deal...the "correct" clearances in floating pins will cause clicking after startup for 30 seconds or so. To prevent the start up noise, the floating pin clearance must be kept so tight that the pins are almost press fit again."

That could explain why some are louder then others.

Well I am glad I found this post!

My 2019 does this. I am taking it into Ford on Monday AM.

Originally I thought it had something to do with the AC system because when I turned it off it quieted down a bit. Maybe it just happened to be a coincidence and it was naturally winding down when I happened to turn the AC off.

Like yours mine only does it on the first start up. I can drive it to work, let it sit, and then come out and go home and it doesn't do it.

 

[mustangflanagan]

Same here..mine has 600 miles on it

 

[Zinc03svt]

Mine was super quiet at start up for the first 1500-2000 miles. Now @ 3000 there is minor clicking/ticking right after cold start. Once warmed up it goes away. Not sweating it folks! Car runs like a beast. Can everyone chill out about this? Lol.

 

[mustangflanagan]

I wonder if any of the shop/genders know about this like Beafcake maybe they can chime in.

 

[stangman638]

No tick again past few days at drive thru or idle for the most part, happened yesterday a little at idle and very little while revving..

I'm gonna hold off on going to the dealer.. 3500 miles.. I'll drive it around for another 1k miles and see where we are at, I do not like the idea of having a new engine torn down if it doesn't need to be, I want to see more pics of damage done from others ticking noise

 

[Turbolag87]

guys chill out. I have the same tick as well and happend after my first oil change. Tick is only there for like4min when cold then it stops. Just SEND IT and enjoy the car

 

[Turbolag87]

i also heard that someone fixed their bbq tick by replacing his timing chain. Forgot where i heard it.
