2018+ OEM Harmonic Balancer

Wow tasca has a great price on them if truly viscous.

This is what the 2021 elastomeric looks like.

Ahhhh yes Sir. 100% correct.

Thanks for posting the link! @K4fxd

I couldn't find it because I kept searching for harmonic damper or balancer.

I was curious to see how much this fluid damper is, but I cant find it anywhere. Was wondering if its significantly less than an ATI. I plan to change the damper whenever I get to the pump gears/sprocket.

You can't get the fluid damper new anymore; it's been superceeded by the KR3Z part number. The "K" indicates that the new damper is a 2019 part number and I know elastomeric dampners are
used on 2020 coyotes.

Could also be the 2021+ has better OPG's.

There's no reason for Ford to upgrade the OPGs, despite all the hubbah on the internet. It has been proven over and over again the stock OPGs are perfectly capable of handling the designated power and RPM limits from Ford. It's only when people take those parameters beyond that that things go south, and even then on very rare occasions.

Ford is not going to spend money upgrading a part that works perfectly fine as is to please the tuner crowd who take their engines to 700+ hp and 8000rpm.

based on that why even bother with a new balancer for 2018-19.

Crazy theory but maybe the 2021-spec higher viscosity oil dampens the OP gear impact enough to not need the viscous damper.

the 2021-spec higher viscosity oil

Before I spend time looking what is the 2021 North American market 5.0 oil spec.
Thanks in advance

If that theory was correct, then you would see a solid correlation between people using higher viscosity oil and lack of failures. At the same time, you would see more of that in Gen 1 TP Coyotes which are spec'd with 5w50 oil. But there is no such correlation that I'm aware of, OPG failures are more directly related to abuse (whether excessive power, RPM or purely bad driving).

If it was that easy to save your OPGs, then the entire billet OPG model would be throw out of business.

 

[engineermike]

I’ve tried making that correlation myself some time back, but sadly, the data set is just too small.

Wow.
Is this more or less a result of oil dilution due to D.I. ?
Any thoughts @engineermike

 

[GregO]

Yup, just as I suspected.
I love Wikipedia reference feature.

Considering a large percentage of my catch can capture is fuel, wouldn't surprise me.

However, do we even know if the 2021 oil pump is the same style as the older year vehicles? Because on the F-150 it's completely different now.

I’m 100% convinced the new 30 end wt. is to mitigate DI fuel / oil viscosity dilution. I’d go as far as saying this is also one of a few reason the Gen 3’s have a 10 qt. capacity sump.
