Good Job!
I've always dreamed of doing something like that, butnever had the courage!
Bravo.
I would assume that the extra oil is necessary, since all of th eoil in the
lines would not drain back unless it was all higher than the engin, but
you still have to correct for it... Hmm, maybe you should do it
mathematically by calculating the volume (warm) in all of the lines,
and calculate the volume/height ration of the dipstick, and make a new
mark on the dipstick that coincides with the oil level.
When the entire system is in operation, there will be less oil in the sump,
and the oil in the sump is necessary for the splash-oiling nature of the
crankcase (someone slap me if I'm wrong here..)
Also, what provisions have you made for pressure losses in the
lines, fittings, cooler, etc?
We still have the problem of oil flowing out of the external parts of the
system (namely cooler and hoses) back into the engine, giving us a false
reading, reading higher than it really is. Perhaps by recalibrating
with a known quatnity of oil, a compensating calibration can be made?
Can the dipstick be re-calibrated to work with the engine running?
With my 911, you are SUPPOSED to check the oil with the engine warm
and at idle! But maybe the splash oiling interferes with that???
As you can see, there are a lot of questions here, and since I didn't
answer them on my own, I never embarked on the project.
