Is anyone using an engine pre-oiler?

Default Is anyone using an engine pre-oiler?

I was thinking about installing a pre-oiler system on both my vettes and was wondering if anyone is using one? If so could you recommend one? Thanks, Paul

I have one of Canton's Accusumps on another vehicle.

While the primary purpose of the Accusump is to
maintain oil pressure in the event that oil moves away
from the pickup and the pump begins to cavitate, when
equipped with a valve, either manual or operated
electrically by a solenoid, it acts as a pre-oiler.

I have the same one and it works like a charm.

Some years ago I got all enthused about building or installing a pre oiler. After thinking about it awhile, however, I decided that it was not worth the trouble and here's why:

The pre oiler primarily helps the engine bearings by ensuring that a film is present upon start up. That's great, except I have never torn apart a modern engine due to worn bearings. I have torn them apart to replace bearings, turn crankshafts and such because of oil pressure loss, but NOT due to normal wear. Engines are taken apart for a myriad of reasons, but worn bearings alone is not one of them.

As a previous poster mentioned, the accusump does indeed provide protection for oil pressure loss while engine is running. It is a much more useful addition than a pre oiler.

My $0.02,

I think's it's a reasonable mod. I'd like to add one someday.

A motor can sit for an extended period of time and still have a film of oil on the bearing.

I am adding one to my motor this year. A moroso 3qt for insurance purposes.

Many drag cars, especially more powerful ones that need to get on the brakes hard at the end of a run will experience "low pressure" or no pressure from the oil moving away from the pickup.

After any amount of WOT runs for over 10sec most of the oil in the pan winds up in the upper portion of the engine, this in turn causing the braking at the end of the strip to move whatever oil is left towards the front of the pan, and the oil pump sucks air.

Question to those of you that run one already. These things are pretty large - where did you put it? Any pictures?

Thanks.

As mentioned previously, mine is installed in another (non-C4) car. I
can take pics easily, just don't think these'll answer your question about
locating one under the hood of a C4.

I recall several pics appearing over in Autocross - most were for C5s,
if I come across one of a C4, I'll post or PM.

But it does not have instant oil pressure. And since the majority (by far) of engine wear occurs upon start-up, why not? I intend to install an Accusump eventually too and use it as a pre-oiler, particularly on cold starts.

If your cars are street driven, it would be dead weight in my opinion. The startup engine wear schpiel we used to hear is long gone. I think the oil standards are SM or SL now(i don't know what that means), not old tyme non detergent pennsylvania crude.

I installed one on my ZR1 due to timing chain rattle at start-up. I used a Chrysler Lebaron convertible power top pump and a pressure relay.
