Does the cummins have a flood mode for after oil changes?

[KingRanch27]

Does anyone know if the motor won't fire if you hold the throttle down while cranking?

On a lot of gas engines you can do this to build oil pressure, but I wasn't sure if a diesel would do it.

I already prefill filters when changing, but was just wondering.

Thanks!

This motor builds oil pressure so fast that it’s not an issue for an oil change. The oil filter drains down to 1/3-1/2 full after sitting overnight anyways.

If you’re prefilling the oil filter be sure to only prefill the smaller outside holes. Prefilling the center hole will send unfiltered oil thru the motor and virgin oil has more large contaminants that you would think.

There is ZERO need to prefill filters or use a ”flood mode” for any engine in production for the automotive market. Your engine parts are still coated with oil and the 2 seconds it takes for the pump to fill the filter will not do any damage. Hell most engines the filter is full just from the cranking before the vehicle fires up.

I appreciate the replies.

Not looking to get into a debate whether anyone thinks if it's necessary or not. Just wanted to see if any knew if it had flood mode.

Thanks!

And I’ve been pre-filling filters wrong for 35 years. Probably going to continue doing things wrong as well!

I didn't see a Cummins in that video.

 

[H3LZSN1P3R]

Brand new rebuilt engine is not the same as anything in this thread that SBC has never been ran and he was also using a drill not starting it so that video is like most youtube videos complete garbage and a waste of time. Yea the oil from the drum is cleaner so they say but thats not always true

The service manual recommends filling the filter before installation.

Maybe i should have clarified. I dont disagree with prefilling the filter. I disagree with filling the outside holes only when pre-filling.

How would you pre-fill a side mounted filter if need be or perhaps an upside down mounted filter?

You wouldn't. In applications where it's possible, it's suggested. It will cut down on the 2-3 seconds the motor will run without lubrication otherwise. Despite what has been said in this thread previously, oil doesn't flow through that filter "instantly".

Obviously pre-filling filters isn't required, or we would see engine failures all the time, and all oil filter would be mounted vertically. That said, it is proven to be beneficial, and for my 80k truck...I'm doing it.

Regarding oil needing to be filtered out of the jug, that's laughable. It's as clean as it will ever be coming out of the jug, and you're pouring ~2.8 gallons of it into the sump.

No its not a gas vehicle there is no “flood mode”

You’ve clearly never seen a contaminant report for virgin oil…. It is absolutely not the cleanest it will ever be in the jug.

Why would the oil manufacturers waste money filtering the oil when it should be filtered in the engine before ever going thru any close tolerance bearings.

Do you even know how the oil flows thru the motor?

Your motor, your money, your call. But if you had seen contaminant reports on virgin oil you wouldn’t want to run any unfiltered oil thru your motor.

I've read many many VOAs, and have paid for several. I feel extremely confident the oil in the jug is the cleanest you're ever going to see it.

Regardless, you do you, and I'll do me.

Thanks folks.

Not that I'm getting my oil advice from youtube, but if you knew who that was, and his credentials you'd probably realize he's not just some random idiot making videos.

Lake Speed Jr. was formulating oils for Gibbs racing; he owns an oil analysis company.

Got some results you want to share?

I have, and will continue to, pre-fill my engine oil filter prior to installing it. I always use the outer ring of passages for the “dirty” side of the system when filling. The air in the system has to go somewhere when the oil is pressurized. Obviously you can’t eliminate all of it, but eliminating the volume of air that’s represented by an empty filter is worth doing. That air is being sent to the bearings, and the hydraulic lifter bodies. This system has already demonstrated questionable premature failures, I don’t see the need to do anything that would exacerbate that problem.

What about the components within the engine that come into direct contact with that virgin oil as it is added via the valve cover? Is there no concern that contamination from virgin oil could potential do any detrimental harm to those components? Not every vehicle offers a direct-to-sump fill port?
