Diesel Engine Pre-Oiler Pump

[yamajason]

Alarm! Alarm! Your driving down the road, in Nevada or somewhere deserted, no cell phone signal, and you have alarms going off on the dash, OIL PRESSURE 0psi

That happened to a guy I knew last year, and before he could shut off the engine it seized up and died. $40,000 later he is running again with a salvage yard engine(engine rebuilt). A Back-Up Oil Pump would have saved his bacon that day.

Some guys get a Spun Bearing after an oil change(especially on older Detroit Diesel engines) others spin a bearing on a cold morning, and sometimes it happens because of the EGR Soot Monster.

Spun Bearings and Camshaft destruction are much more likely after the truck has sat for a week off work and the oil drains to the pan. Get sick or injured and take a week or 2 off work, the last thing a guy needs is a $5000 - $40000 engine breakdown to deal with when he comes back ready to work.

Hate to sound like a marketer here, but here is cut-n-paste things I found to support spending $$ on this project.
A Pre-Oiler Pump could have saved a lot of life on those bearings and camshafts.
"Cold Start Scuffing". During the initial start-up of an engine the lack of any type of oil pressure leaves the cylinder walls, bearings and valve train without the necessary oiling cushion that is normally provided by the engine oil pump.

80% of all engine wear occurs at startup. The longer it has been since an engine was last started the greater potential for wear!
Pre-Lubricating any engine before it is started will decrease or eliminate the overall wear normally associated with the "dry starting" of an engine, thus extending engine life.

After a week, even oil that normally is in the small oil passages and oil galleys has run back into the oil pan, making the initial starting of your engine even harder on the bearings and valve train components. "Why?" Because now when starting the engine the oil pump has to fill all of the oil passages before any oil gets to your bearings or valve train...on some engines this can take 5-10 seconds or MORE.

A Pre-Oiler and Back-Up Oil Pump could be the best investment to keep your truck engine running for 1M+ miles.

I am looking for an engine Pre-Oiler and Back-Up Oil Pump combination for a 15L Cummins ISX diesel engine that uses 15w40 oil.

My main questions to the manufacturers technical sales rep are:
Will this reliably perform 5x a day for 300 days a year, sometimes in -15F weather.
Will your pump flow oil thru it in the de-energized state if it has 50psi of engine oil pump pressure to it? (which would require a solenoid to interrupt)

so far, I am looking at the $300 GP301-12 – 12 VDC / 10 AMP / 60 PSI / 3 GPM – 11.4 LPM

I want to install a Pre-Oiler pump in a few weeks when I install a new cylinder head and camshaft. Also going to do the Engine Oil Pump shim to raise engine oil pressure 5-10psi at idle.

Do you guys think the best engine oil ports to use for the Pre-Oiler / Back-Up Oil Pump are the 2 ports on the oil filter housing that were intended for Bypass Oil Filter installation? I would like to avoid adding a shut-off solenoid in line with the Pre-Oiler / Back-Up Oil Pump

I need some clarification, if the pump spins freely when it is not powered, it would allow oil to bypass the oil filter and return unfiltered to the engine, right? I don't understand how the bypass part of the Oil Filter Housing works... if a hose were connected to the 2 oil ports on the housing(hose port to port), would the oil flow unrestricted thru the hose all the time and very little would go thru the higher resistance oil filter? Is there a Bypass Valve somewhere in there?

An updated lubricating oil filter bypass valve is available for certain ISX engines (does this valve control flow thru the Oil Filter Housing Bypass Oil Filter Ports?)

Saw some Oil Bypass Filter kits return oil to the bottom of the pan, at first I was thinking that is an unnecessary risky location.

Im thinking it might be the perfect place to get a lot of oil quickly to a Pre-Oiler Pump. I could probably use one of the EZ Oil Change valves and run the hose to my pump.

Seems very smart to me.

Idea pre lube engine was already here before last forumquake.
Here is link to another manufacturer http://www.varnaproducts.com/EP-4_Pump.php
Someone did call them to find out the price and price was $240 if my memory still intact.Everything what is related with avia is expensive due to FAA certification requirements. Varna pump has check valve integrated don't have to worry about.

I called Varna, it was over $600(I think $685) and they could give us 20% discount if we ordered 10 of them. It is rated 1.75gpm @ 60psi. Their main claim with their pump is quiet operation.

The $250 unit was from a motorcycle racing store and is rated 2.0gpm https://www.rbracing-rsr.com/eatshit.htm

The $300 one that airplanes use is rated 3gpm @ 60psi
$300 GP301-12 – 12 VDC / 10 AMP / 60 PSI / 3 GPM – 11.4 LPM

To be fair, the rated flow of the pumps doesn't specify the Viscosity or Temperature so it is hard to compare which moves more oil.

Here you go, maybe this will help (Huge THANKS to Daniel Babbitt for the videos)

Pump looks promising, I have a cm 870 my oil pan has outlets on each side about half way up the pan.also at the top of the pan along the block I think are access for the pressure line return.
