Stage 1 Comp Cam HV Oil Pump and Lifters

[bitdrive]

So, a few weeks ago after installing a super 10 cat back system on my 2015 Ram -with MDS- I drove for a few days and using the gear +,- to select 8th gear while driving making the exhaust sound better - I had a lifter failure.

Stopped driving immediately once home (less than 15 km away from where I heard it happen) and found a local shop we've used to do the repairs.

I considered putting a brand new crate motor in, even a 6.2(?) swap, or just to upgrade the lifters and cam to non mds, and get a tune.
This route became the most likely as i'm only in town for school and only had 4 weeks to have the work completed.
Well, last week the parts have begun to arrive. The HV oil pump is on, cam is on the way, and lifters are arriving wed.

Need also a tune to remove the MDS from the computer and needed a new water pump.
We are looking at 10K CDN for the work. When they checked the MDS solenoid they my mechanic said there was a very tiny amount of metal in the screen but likely I'll be fine after several flushes through the galleries.

I just want my baby back here. It's been weeks and I miss her terribly. Any input is welcomed, and is it a good idea to install exhaust headers while this work is being done? Or at least upgrade the exhaust manifold bolts?

Thanks for reading and I'd love to hear your feedback. Cheers

Edit: I forgot to mention the Stage 1 Cam and new lifters are NON MDS. Finally.

Good luck with the time factor.I really want that pump.

Have your guy pull the VVT solenoid and check it for metal flakes to. Which high volumn pump did you go with,if you went with the Hellcat pump,install the stock bypass spring from your old pump,if you went with the Melling pump,install the lower pressure 60 psi bypass spring,if you don't theres a very good chance you'll end up with oil pressure codes.Install long tubes while it's apart,they'll really compliment your cam,and make sure you have him remove the mds solenoids,and install Ma Mopars block off plugs,that way you'll have full time oil flow to the lifter bores.Who's tuning it for you?

Look in to Johnson axle oiling lifters. Yes, they're expensive. But you won't have another lifter failure due to lack of lubrication.

You can have all the oil flow in the world with OEM lifters and they'll still fail as the rollers are lubricated via crank sling. There's an oil passage for MDS that sits directly below the cam blocking a majority of the sling. Lifters also sit at a very shallow angle limiting run down.

5.7 and 6.4 are just poorly designed blocks when it comes to lubricating the cam and rollers. Johnson lifters are pretty much the only solution.

If you have a high volumn oil pump,then the Johnsons are the way to go,if you have the stock oil pump,i'd avoid them,as the stock pump doesn't have enough volumn to offset the extra leak the Johnsons create.Been a few guys burn up bearings using the Johnson lifters with a stock 5.7/6.4 oil pump

I suggest it for sure.

Some info on the oil pressure I’d say it’s roughly 100 kPas increase in pressure. 500 at idle and 545-560 under load iirc.

I’d love to her my baby on a dyno for more detailed info

Change you're evicc settings to SAE,and give us the hot idle psi pressure and pressure at about 1800/2,000 rpm driving down the road,as 14.5 psi over what you had,doesn't really mean much,when we don't know what you originally had.

 

[DILLIGAF]

We talk in PSI on here dude

 

[Riccochet]

The conversion from Canadia units to Americani unit is 72 PSI at idle and 81 PSI under load.

Still, that doesn't translate to better oiling of the cam and lifter rollers.

Sorry forgot to add OEM readings.

On average difference would be 75-125 higher psi - give or take - while now using the HV over OEM

OEM numbers weres Idle: 350 psi, load: 400 psi - IIRC

when mds was being deleted we had a shop travel to their shop to tune ratios and tolerances after the delete. I don’t know specifically exactly what was changed and to what though. I’d like to find that out with a phone call

You might want to set your Evicc to SAE and get the correct numbers,as no way in hell are you seeing 350/400 psi,you'd blow the filter right off the engine at those pressures.
Sorry kid you're wrong again

that'd blow just about every seal on the engine. Rear main straight to Narnia.
