Does anyone have any experience with "pre-oiling" systems that bring oil up to the top end prior to start-up?

cheap insurance, they also eliminate risk from starvation in hard turns

I've not run one, but I will be adding one when I put on an oil cooler

Pedro (bmw1602.com) has a good write up on his installation on his site. I'm thinking of getting one too.

yeah...

The electric 'fast- in slow- out' valve is worth the money.

Otherwise you have a problem pulling away from lights

where the sump's filling and you have 20 psi-

and 4k rpms...

it also makes checking the oil level a little entertaining.

If you drill the tii pump oiler boss on the oil filter holder,

you can attach the sump there. I think I got a 1/4" fitting

to work, and opened the inside of it a bit, and that did a pretty

good job on an otherwise stock engine.

But it's not really worth the $$$ or the hassle unless you

track the car- or have an oil- leakdown problem with your motor...

fwiw,

I never hear this pulling away from the light business...

well, for the street the valve is worth it since you are starting and turning of the car all the time and messing withe the valve all the time is a pain.

for the track(like me)......you only turn on and off the car a couple times a weekend so....

$7 for the manual valve, $100 or so for the electric.

easy choice for me..

Yes, I totally agree-

on the track, an open system will work ok. It fills a little too fast (I run a restrictor) so that your oil stays artificially low as you come out of the left hand sweepers, but not so low as to kill you.

On the street, you're sitting at a light for 2 minutes. All 2.5 extra quarts drains back into the pan, because your idle oil pressure's like 15 psi. Then you floor it- with an open system, the pump's immediately trying to fill the sump, and you're headed for redline in 1st. With maybe 25 or 30 psi at the bearings. Enough, maybe, but way less than ideal.

With the electric valve, you immediately get 50 psi at the bearings, and the sump gets a trickle to start refilling.

FWIW ;-)
