New Project: Engine Pre-Oiler

I have a project to complete for my CAD Engineering class. I've decided on installing an engine pre-oiler, using this kit: https://autoenginelube.com/ What do y'all think? Any suggestions? Me and my partner are still in the planning stages, but we do have the go-ahead from our instructor.
 
Sound like an idea with a basis in logic. Are you using this kit as an idea, and engineering your own, or buying the kit and the install is the project?
Either way it's intresting.
 
Prelubing an engine is never a bad idea. And for a class project, it's a great idea. But is it a necessary item that should be installed on all engines? I have a 1986 4 cyl Ford Ranger pickup that I bought new in 86 for a shop service vehicle. It now has over 200 thousand miles on it. The oil pressure is only 5 lbs lower than when it was new. The engine has never been apart other than to replace the timing belt at 100 thousand miles. We still use this little truck around the place on occasion. It never fails to start. Best little 4 cyl engine I ever saw. It's oil, (Penzoil) and (Fram), oil filter are still changed every 3000 miles. PJ
 
We had designed a system initially, but it was actually cheaper to buy the kit (and we're getting a nicer solenoid too). We're kind of on a tight deadline, as it stands now our previous project will not be completed in time, so we need to do something soon to get credit. This should do the trick.

Can anyone say Accusump?

I don't guess so, guys, we have been using pre-oilers on the British race cars for 30 years, both electric and manual valve.
 
Part of the important properties of oil is a factor called boundary layer lubrication or it's ability to lubricate just because it exists in the mechanical clearances of something like a crankshaft bearing. Generally, it is able to protect the bearing surfaces until oil pressure is regained. Obviously, the time it takes the oil pressure to build up is critical and changes as the engine gets older. Once the pressure builds up, you get a hydrodynamic layer which is what the crank "floats" on during regular operation.
 
If your car has been sitting for a long time and you are worried about a "dry start", crank the engine over for 15 to 30 seconds (or so) with the ignition turned off, to build some oil pressure.

Then turn on the ignition and start the engine....sort of a "poor man's pre-oiler" (this is what I do on my race car).
 
Hap, back in '69 or '70, i made one using an accumulator from an F-100 fighter. I was racing at Riverside, and there seemed to be a lot of interest in it. Did I inadvertently start something?

Pre-oilers are very useful for cars that sit for long periods without being cranked over. A lot of damage can be caused in the few short seconds of nearly dry running. They seem to be especially popular in older cars with less sophisticated lubrication systems.

Another unit that is helpful is the post oiler for turbos. It maintains oil to the unit during spooldown.

I'd have to get a turbo first. Wait a second...idea brewing... /bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif
 
I ordered the kit today! It should be here next week. Once I begin the installation process I'll be able to figure out the length of the lines I need. Since installation will be via the oil cooler lines I plan on upgrading to stainless lines - I seem to recall Moss having various lengths availiable.
