Anyone ever seen/used/heard of one of these before..

sounds like a good concept..

Nice
 

I think I have seen something like that on a race car with a "dry" sump oiling system:D

They had them before the 2nd World War.

There are a few engines nowadays that might not like the early flow of high pressure oil.....Audi and VW 1.8 turbos for two.

These engines have a habit of over pressurizing the valve lash adjusters and bending the tiny valves on start up.....but in it's defense, it is usually a jambed oil pressure relief valve that does this on the stock equipped engine.....nasty :rolleyes:

If the oil pressure was less than 30 psi, I suppose it wouldn't hurt.


.

If it takes several hundred revolutions of your engine to get oil pressure you better spend the money on repairing your engine (or get a new car).

I was considering a similar product from Amsoil, but I believe it was about twice the price of this unit. I'm not convinced that there is all that much advantage for a daily driver (mostly if you are using synthetic oil), but think it's a great idea for those cars that sit for longer periods like many of our Mercedes classics.

I bought one recently for my 6.9 whose engine is being rebuilt.
Always liked the idea, though I have many posts here from people who don't like them. I don't think the design of my car is lacking, it just seems like cheap protection.

I haven't yet figured out how to plumb it in, but I am working on it.

If a car has sat for a longer time it is best to prime the oil system by letting it turn on the starter engine for a while without plugs. This way you oil the bearings without pressure on them and also oil the cylinder walls.

The pre-oiler system has been on the market for decades by different manufacturer. If it were that good, you can bet some engine manufacturer would have included such a system in their design.
It really solve a problem that never existed and give answers to a question that has never been asked.
Gadgets will always sell, thanks to excellent marketing campains. A good example is the dozens of miracle additives that are suuposed to bring unlimited benefits

This product is used on a lot of classics that are driven very infrequently. I called up a couple of car museums to find out about this and the number of cars that use them are limited, usually they are vehicles whose former owners equipped them with this device before the car was acquired by the museum.


There are less expensive versions of this device, too. Some are used on VW 181s, f all thins!

I've used these on race engines. Not only do they pre-oil the engine, they maintain pressure when the car is subjected to high G-forces. The most commonly used product is Accusump from Canton Racing:

The generic name for these products is "oil accumulator", there are a few brands.
