i have been looking into a pre-oiling setup to get rid of the startup chatter on cold mornings & i came across a system that uses an air charged cylinder that keeps a reserve of oil on hand in case of loss of oil pressure or for building oil pressure prior to startup.

i was wondering if anyone had any expierience with these kind of products or pre-charging the A4's oil system before startup (check valve problems etc..)

with the added benefit of 'dry sump'-type operation if you ever experience oil pick-up starvation in the oil pan with high cornering loads.

just wondering if anone had any expierience with one on an A4/S4

IIRC there are around 4-5 check valves in the oil pan alone, id hate to hook it up &amp; be blocked by one......

Update: I changed the picture to reflect John's suggestion that the oil should flow through the filter first.

--------------------------

I'll be putting in the cooler this weekend using a perma-cool spin-on adapter. However, this picture represents future (Aug - Sept) plans.

Take a look and let me know what you think. In particular, is the oil flowing in the correct direction (filter then cooler) or doesn't it matter? Could the system be simplified in any way? Also, what size lines and connectors does everyone reccomend? The cooler is going in with 8AN Earl's Perform-o-flex hose, 8AN Earl's Auto Fit Hose ends, and Earl's 8AN to NPT adapters (1/2" on cooler side, 3/8" on spin-in adapter).

looks good to me

Did I guess right on the direction of the oil flow (cooler then filter), or doesn't it really matter?

I would guess that it doesn't matter, since it goes through each component before getting into the engine, but I'm not certain.

I'll sell it to you cheap.

don't want any excess junk building up in the cooler/thermostat.

Do the 12V's have the water-cooled oil filter housing?

If so, you'll probably want to remove it, as there's no sense in cooling the oil, then heating it back up.....

What's the Take-Off Plate do?

good point......
