Whats the build date on your 19?

Truck 7-19 Seems like engine was built 5-19.

I wonder if the 2019+ valve springs are any stiffer than the earlier 6.7 valve springs?
Normally the cam profile is more aggressive with roller lifters and then the valve springs have to be stiffer.

No idea. I definitely notice a wobble and bounce pattern on the cam after the roller leaves the top of the lobe. Also the axle of the roller rotates and has slight play on the Cummins lifter.

There is no pressurized oil feed though. Going to call Wagler and ask if the Jesels have a pressurized oil feel to the roller bearing. If so, will buy. If not, I’ll just get new Cummins rollers.

Also, for @krs and @H3LZSN1P3R, timing case, cam, and lifters are made in USA.

EDIT: See post #89

So the Wagler Jesel lifters do not have that oil feed as they say factory ones don’t have an oiling problem. They state the wobble and bounce is from the hydraulics.

So, I ordered new Cummins lifters from Chrysler. About a week out max thankfully at $87 or so.

Just as a warning, I’ve found that the lifters with 2 grooves machined in the upper neck have more wear than the later smooth style. IMO, It’s best to upgrade to the later style.

Also just my opinion, if anyone does this swap before 20k miles, I believe it’s OK to run the factory lifters and cam.

Slight discoloration is fine, but if it has discoloration plus scoring, I’d say replace.

I dont have the door sticker that says mfr date since door was replaced but i know it was one of the last ones off the line for 2019 so i hope mine is good lol i have no sounds though

 

[elephantrider]

mine is one of the 1st ones lol i may be in trouble.

Well just hold your breath that there is a recall like the CP4 then you can put more better parts in and get reimbursement lol

I wonder what the price difference is between the Mopar/Cummins roller lifters and the Jesel/Wagler roller lifters?

Before I installed anything, I would want to closely compare and examine the original lifters with the new Cummins lifters and the new Jesel lifters, trying to determine which is the best choice.

And closely examine and compare the original camshaft and the new Jesel camshaft.

Knowing @cumminsturbofreak , that's exactly what he will do..

my build date is 05/19, so def an early one.

$87 a lifter for Cummins. And as you can see the new smooth style looks great. For 12 is $1,044

$220 a lifter for Jesel. For 12 is $2,640😵

Since Jesel doesn’t use anything different for oiling, I’d only use it if going with stiffer springs.

 

[cumminsturbofreak]

This is how I’m reading a wobble and skip with hydraulics. I’m assuming that’s the noise we hear at 1500+ rpm. We’ll see after the swap if I’m right.

 

[elephantrider]

def looks like its jumping.

 

[krs]

Gross.

 

[cumminsturbofreak]

I’m guessing this bigger lube groove (which supply oil to roller) is the reason the newer roller wears better.

Well if I don’t rent my lifter tool out or sell it to you, I may sell it to Wagler.

So anyone wanting to do this please let me know now.

 

[elephantrider]

your making me think about selling !!

 

[Shock88]

maybe i missed it, but r u keeping the hydraulic lifters or putting in that spacer they sell to make them solid and getting adjustable rockers? (like it should still be from the factory) 😩

 

[cumminsturbofreak]

Spacers obviously

 

[StealthDiesel]

Lol... I hear that the 2021, 2022, 2023, 2024 trucks will be perfect!

 

[elephantrider]

I'd be going backwards on year models!

Every gen has one problem or another. FWIW, I prefer the new trucks with a couple fixes then old trucks with much more fixes.

 

[elephantrider]

no doubt... they all have issues. cam blank softness issues wasn't one of them, though.

was it?
