I have seen this unit installed on a gas engine, and when the ignition was place to the on position (before starting engine) the oil gauge actually showed oil pressure.Gary - K7GLD said:"I have a Frantz for mine, but if I had to do it again I believe that I would get the Amsoil BMK11 and add the preoiler that bolts up to it. "
You know, that pre-filter does look interesting - but a question after reading the installation instructions on the Amsoil website:
IF the oil system attachment point is used as they suggest, that pre-oiler - or any other, for that matter, is dividing it's lube flow between the bearings, where you DO want it to go - and ALSO a percentage is traveling back thru the oil pump into the oil pan. In other words, ALL the lube flow is NOT going ONLY to the bearings where it is most needed - and for that matter, very little or NO prelube gets to the cylinder walls prior to engine startup , and THEY are still dry until normal flow after startup...
An added question as to the Amsoil unit is reservoir size - 160 cc is NOT very much volume (about the same volume as inside a toilet paper core), especially if a significant percentage of that volume IS lost, as I suspect it is - think about it, after the oil drains back outta the various engine oil galleries back into the pan. 160 cc might not even be enough to refill those galleries! Would it help? Sure, but enough capacity to truly PRESSURIZE the entire system would be my goal...

Thanks for the response Wayne - but do you suppose the registered PSI was OIL, or the PSI resulting from a mix of oil and a large volume of trapped AIR left in the oil gallerys after the oil had drained back into the oil pan when the engine was shut down? The oil pressure guage sure won't know the difference between oil, OR air pressure in that case...
I suppose the only REAL way to check, is to pull the pan off a test engine, and see if and how much actual OIL is seen to be flowing from various main and rod journals - or if what appears is largely air bubbles...
Like I said, it's a good step in the right direction, but personally, *I* would prefer a reservoir source closer to a quart or so for a no-doubt-about-it supply that will purge all air from those drained oil galleries, and actually pressurize them with OIL prior to startup...

The "Moroso" pre-luber is a larger unit, measuring about 18 inches long, so installation is a bit more difficult, and it also uses compressed air to operate, and could be a source of contamination, such as moisture etc. The unit must be manually activated under the hood!RedRam401 said:Morosso makes the "Accumulator" in either a 1. 5 or 3 quart size that would handle what you want.

You would have to supply your own solinoid valve.
After turning the key there would be plenty of time for the oil to flow while the grid heater does it's thing.

IT DOES HAVE A LARGER CAPACITY... ... ... ... ... ... ... ..... but is it needed?

RedRam401 said:Hey Wayne, the Accumulator does not need compressed air to operate, it uses a sealed piston that is displaced under oil pressure which compresses the air on the back side of the seal. Then either the mechanical valve or a solinoid controled valve closes.
At that point the gauge shows the amount of air pressure on the backside of the oil seal. When the valve opens the air pressure pushes the oil into the engine.
This unit was originally marketed to racers to gaurentee oil pressure should the pickup become uncovered due to G forces, one of the reasons for the manual shutoff.
I have seen these for sale with electric solinoids included, but can't remember where.

I guess I'll bring this one back up...
Has anyone installed one of these systems? From my understanding, there is no pump on this system; rather, it simply delivers a little 160 c3 shot of oil, and has to be recharged by the engine's oil pump after it starts... is this correct?
Because of some disturbing wear that I found at only 57k miles, I'm contemplating adding a pre-oiling system. However, I would like to have something that incorporated an electric pump. This way, I could have the electric pump run for 20 seconds or so until oil pressure was verified on the gauge, and then the truck could be started. I would also like to use it on a timer for a post-oiler, to allow oil to be circulated through turbo bearings, etc for a few minutes after shut down.
This may sound like overkill, but I just can't seem to get to the place where I feel compfortable with the longevity of this truck. I've been running Schaeffer's 9000 5w-40 oil, Donaldson Endurance oil filter, OilGaurd bypass filter, and FilterMag magnets on the primary... and still, the Blackstone reports come back indicating high wear with only 8,000 miles on the oil.
When doing a partial tear-down and inspection of the engine last weekend, I saw evidence of above normal wear as well on the rockers and trunnions.
Does anyone know of a true pre-oiling kit that will allow oil to be pumped up to pressure before starting? The 160 c3 shot that the Amsoil Oiler only gives around 10 tablespoons of oil, or about 2/3 of a cup... that doesn't seem real assuring to me.

As far as pre-oiling goes, the valve trunnions/rockers (as you call them) are not going to be affected, as they are not pressurized as I understand.
Might check these out. They are built for airplanes, but will accomplish what you are wanting to.
