BBQ tick - another attempt to understand

[careature]

Would like to share my info from Ford powertrain engineering on the BBQ tick (the random metallic tick at bottom end at idle - Typewriter nosie). From my understanding they dont know what exactly causes the issue on the 5.0, with some engines the oil is forming tiny air bubbles and popping like bubble wrap when getting hit. This is the same tick issue that they had on the diesel engine for 11 years (TSB 46407), which they just solved (I think) last year by re-designing the oil pump. I have been told by egineering there is no durability issue with this BBQ tick, they call it typewiter nosie. Was told by changing to different oil, weight ect... can stop it. Also mixing a teaspoon of a very fine carbon powder that is an ingredient in womens make-up, in a half quart of oil. And pouring it in will stop air bubbles forming instantly, no more tick. I will have this ingredient tomorrow and trying it, on my engine.

How did they come up with make up powder?

Why engines from factory do not do this ((mostly)? What do they add from factory?

What oil models are less prone to this?

My thoughts on this are kind of coming to fruition after a bit of theory I had in the past. This may be a cavitation issue. Carbon powder additive, may be changing the cavitation property of the oil, similar to what happens when you add a Moly additive. This is probably why people who are using Ceratec are almost immediately making the BBQ tick go away.

Ceratec not only has that hBn surface treatment, but it also has some Moly in its formulation. It may be killing two birds with one stone by treating the cavitation issue, but also adding a more slick surface for all engine components.

It's a very fine carbon powder. It's cheap to buy and at the right mico size. Used to make make-up.

Some engines do it right away, some do not. Mine started at about 100 to 500 miles.

I would not use Motorcraft 5W-20 on a high performance engine.

I dont know how believable this is.

What happens if you don't hear it idle only when slowly revving engine to 2200 rpm? Your saying that rapid tick that is normally acting as typewriter tick isn't metal on metal? I used to hear it at idle on cold start but after 500 or so miles on oil change, its only heard now when putting foot on gas pedal, revving, or slowly driving down the street.

The fact that a tune to the car brings the noise back at idle.... How would you explain that than?

I'd preffer some additive to make up powder... at least they are tested to some extent.

I would not use ceratec after seing pictures on how used oil with it looks like.

IMO this is a cavitation issue for the BBQ Tick. Too many videos of cavitation sounding the same as BBQ Tick.

Ford engineering told me it is NOT metal on metal contact, its typewriter nosie, what people call the BBQ tick. Tiny bubbles in the oil forming and getting hit, producing that metallic tick.

I noticed this typewriter tick in a month of car ownership. At 9k shortblock replaced and I was told - rod bearing at cyl 4. So how come it is not harmless...

Why would they be replacing parts that wasn't damaged.

Because I think some people are getting rod bearing damage. It could be independent of the tick, or the tick/cavitation is forming small bubbles in the oil, which momentarily is causing a tiny spot of no lubrication. Thus, journals exposed to cavitating oil may be slowly wearing out faster. Just a shot in the dark with that idea, but seems to make sense.

I was referring to this part of post above:

"I have been told by egineering there is no durability issue with this BBQ tick, they call it typewiter nosie. "

Right at idle its typewriter .. revving to 2200 is not typewriter in nature, but the same noise tapping/ticking at a much faster pace...

What is hitting the bubbles?

This is what I was told by engineering. Maybe yours wasnt the random typewriter nosie, I don't know. I know a few people including myself that have many hard driven miles and many, many passes at the track with the tick and no performance issues to report.

I will find out tomorrow if my random tick is gone.

Do you have a link on carbon powder and sources to buy?

Personally, if a Ford tech actually told me to add carbon, then they must not be too concerned about the use of oil additives voiding warranties. I personally would try a small amount of Liquid Moly, or a half bottle of Ceratec, before I put women's make-up in my engine oil.
