Engine pre-oiler... anyone make one?
Posted by: Brad54 ()
Date: November 03, 2010 06:14PM

So I just took a worn out distributor and made a pre-oiler for the wife's engine.
It's so amazingly simply, I'm curious if others have done it.

The temporary engine we're dropping in has sat for a long while, and I'm going to pre-oil it before firing it up.

I'd recommend the same for anyone taking a car out of winter storage.

Yep... the only way to go. Beats the hell out of the sawed off screwdriver! angry smiley

Oh.

I thought you actually installed a motor on the distributor top etc. That'd be just keen to have!

I used a large Crapsman screwdriver that fit just right into a socket and drove it with my 'lectric drill. Cheap and effective, but not as cool as a purpose-built tool would be. Gotta check and see if I have any more sewing machine motors laying around...

I make the spin-in-a-drill type for any motor I'm rebuilding.

Back in '82 I was bored and made an onboard version (which I called the Pre-Oiler) for the first Corsa I restored. It used a solenoid, an old fire exinguisher and a flexible grease gun hose tapped into the oil filler/alt. adapter plate.

When you first start the car the solenoid would open and fill the fire extinguisher with oil under pressure. While doing hard cornering, the fire extinguisher reserve tank would help supply oil back into the engine for a short period of time in the event that the oil pickup was starved.

Before I would shut the car off I idled it up briefly to build good pressure in the tank and then when I turned off the engine the solenoid closed and I had a small tank of pressurized oil ready to release before the next start.

The next time I went driving I would first turn the ignition to "run" position so the solenoid would open and release the oil. I waited until I saw the oil pressure light go out and then I would crank the engine.

You can buy systems like this of course but I wanted to make my own back then. These days after a long storage I just disable the spark and then crank until the oil light goes out. I then enable the spark and start it up.

I also use an old distributor. The weight/springs have been taken out as well. Sure makes priming the oil system easy before that first start.

A distributor is the only way to go. It saves the bore in the rear engine housing from getting screwed up. When you use a mashed down rod, or a cut up screwdriver you have the potential to nick and score that lower bore. That lower bore is the second "bushing" for the distributor shaft. Fairly important for that bore to not be mangled or sloppy.

On some V8 engines like thee SBC you have to use a modifed distributor. One of the oil passages runs around the housing. If you don't use a cut down distributor part of the engine isn't pre-lubed. Luckily the Corvair isn't like this.

Ideally if you pre-oil the engine, you'll also slowly rotate the engine by hand while turning the oil pump so you make sure all of the bearings get a chance for the holes in the bearings to line up with the holes in the crank throws.

An old Corvair distributor shaft and an electric drill motor works wonders. No modifications necessary.

Gee, somehow I was thinking along the lines of an accumulator for start up oiling
when I saw this post. Anyone here done that?

What I'm talking about is for everyday use, so there is instant oil pressure on starting before the oil pump gets up to pressure. when the engine runs oil is pumped to a small tank with a bladder and a check valve. Next time the engine starts the pressure 'accumulated' is released immediately. You are talking about a priming type setup for after a major service event.sad smiley

No I'm not.

This system was installed onboard, behind the battery area, and I used it every time I started the car. That car was sold years ago (with the system still in operating condition). If I stilll had it I would have included photos.

If you will read past the first sentence of my first reply you will see that I discuss an entirely different system for daily use.

Electric pre/post oilers are available. - we installed one of my pal's truck. Sure was cool to hear it pump up before cranking the engine.

I believe we also added an Amsoil filter block to the system, too - he was all set for loooooong life out of that engine, 'til my dad bought the truck from 'em... and crashed it thanks to a construction flag man who waved through two vehilces 90degrees out into the same intersection... The minivan took the brunt of it.

I take the ops out of the oil pump housing and install a oil presure gauge,,put in the modifide distributor hooked to a cordless drill,,run the drill till the oil presure gauge has pressure,,then tap the starter with a remote start button to turn the motor to get oil in the mains and rod bearings,,install dist and fire away! I like the oil presure gauge on the motor for a first start to make sure I have good oil presure thumbs up

Hey Brad,
I welded up an oil cooler adapter to have an extra 1/8npt tap for cool, filtered oil delivery to the turbo bearing. Thought about putting an extra fitting in the line for an on-board, electric pre-oiler pump. Something cheap like this might actually work if you never let it get too hot:

for a couple bucks more this would be better:

Buy a couple check valves from McMaster-Carr and run an intermittent button on the dash so you only run it when the engine is cold. My idea was to run it's own oil pick-up and filter.
Lot of work.

MOROSO makes an oil accumulator for this very purpose! They work great on street or race/off-road engines. I think the kit is around a couple hundred bucks, though we made our own for several race cars.

I use the drill and screwdriver method myself. An old dizzy would be nice, but I always seem to lack that...

I am confused as to why you are making this. I understand about wanting to make your engine last longer by getting oil pressure first but wouldn't this be easier?

Just hide a toggle switch under your dash that cuts off power to the coil. With the toggle switch in the off position so the car is not firing just crank for a few seconds to build oil pressure. Turn the switch back on and crank again to drive away.
