Pre-oiler, pre-lubricator, Accusump

Hank,

More SS on the dash too! Can you ever have too much stainless? Isn't there a fellow with a SS body on his Cobra? And the DeLorean had a great body too...as cars go.
So are you going to go for it? Sounds like you're having fun with this anyway!

All the best,
Randy Klein

Zderf,

So that's what that valve's for, to charge the cylinder with 7psi! Live and learn. I too have the 160 psi gage and have yet to see the oil pressure get much past 55 psi, as I'd expect . I can read the gage easily though. Still, I will check into changing it in the future.

Glad to see that it is coming together for you!

All the best,
Randy Klein

Zderf,
I saw the gauge graduation but have not had time to think about it. ilike you fix and will go that way. thanks.

Randy,
Having more fun with the metal work than anything else, so far - driving will change that. Trade off with SS is weight over AL. I'm gonna dump the upper rear spring mounts and buy some weight for the fire sup. system and maybe that dash.

I have just installed a Accusump also, it was very easy to do and it looks great.

In regards to the gauge, I precharged the system until the needle just came off the peg, as the oil entered the cylinder the pressure rose to about 55 #'s.

I have several similar systems on some heavy equipment that require a precharge with dry nitrogen. The main failure with most of these type systems is corrosion on the (air) side that causes the seals to wear.

Scott... any digital pic's you could Email? Would like to see your installation.

Thanks...

I just found your site and it is great.

I've just completed my Unique 427 S/C, complete with 427 side-oiler.
I installed a Pre-Luber from Engine Lubrication Systems (www.enginelube.com)
It is an electric pump which picks up from a drain plug fitting.
It appears to be of high quality, if a bit noisy, and gives me about 45 psi before I crank 'er up.
I used braided AN lines and installed a diverter valve which allows me to pump out the oil through a hose without having to jack up the car. Much less messy.
I ran the pump output into the filters input to make sure that no unfiltered oil gets into the galleries, the engine's oil pump will only allow a small amount to bleed back into the pan.
With what these engines cost, I feel it's good insurance.

Later,

Hi Cobranut, Were happy you found Club Cobra!

You might want to check out Petek's website, I think he has the same system as you.

Make sure you send in some photos of your ride to post in the members ride section.

Bringing this back to the top to make it easier to find. I still think this thing is a great idea !

I got my Cobra's Preluber fired up 'bout a week ago. Less than 20 seconds the oil system is pumping along at 55psi. Noisy pump, but it works well.

One thing I didn't like was the PreLuber control module - so I'm designing my own (I'll have info on my web site in a few days).

It looks like some folks might be able to use this discussion.

To the top once more.

I love my pre-oiler

Randy....

Hey, I love mine too. One odd thing tho. The solenoid valve is directional sensitive. I have the "out" side of the valve towards the filter block supply. When I first started using the system, I would recharge to about 60psi then shut it off. After running and shut down, I would notice the pressure was at 80psi. I attributed that to expansion of the oil due to heat.

Guess what.... I think the solenoid valve permits oil to enter even when de-energized (it is a normally closed valve). It does not, however, permit the oil to flow out when de-energized.

As such, I simply leave the valve open until the car is at operating temperature, then close it knowing it will be at whatever max pressure it saw before it shut down (usually between 60-70psi). Also, by sutting the valve off early, I then won't forget to do so or won't have to race the motor to recharge if I've been running with it open all along.

So, what I first thought was a negative issue has in fact turned out to be an OK thing. Thus, I have not contacted Pegasus to raise a stink about the valves characteristics.

May You Always be Under Pressure!!

Your right about the constant fill capability of the solinoid valve. But you defeat half the purpose of the ACCUSUMP by shutting the valve when you do. It is there to maintain constant oil pressure in "adverse" conditions, such as long hard cornering (see highway ramps)when the oil goes to the top and doesn't come back down. Or how about the possibility of taking a good one in the oilcooler from road debris (or the oil pan for that matter). I holed my oil pan once, and it saved the motor. I have also had an oil line burst at an inopportune moment and I was saved again. They cost enough, don't waste half your investment.
If you have CRS like I do, wire the hot side of the manual switch to the IGN.on post and it will lock in pressure when you switch off the key and release it when you turn her on.

A427SC,

Hey, thanks for the advice on keeping the sump active during use. Your points are very well taken.

As for wiring the switch, I think I'll keep it as-is... will just have to be alert to closing it at the right time. Since my oil pressure at key-off is usually idle-value, I don't think thats gunna work for me. As well, I pre-oil prior to key-on for probably 60 seconds... and don't wish to have my fuel pump howling during that period (it would be fooled into thinking the engine is running due to pressure on the pressure safety switch).

Anyway, various senarios, nuances, and points of view... thats what makes things work so well!

Rob;
how do I contact you abut purchasing the preoiler?

This question keeps floating to the top; so here is another float!

All of you considering building a reliable engine might be interested in this thread!

All the best.
