The thing I really wanted to do was some sort of an adapter to the dipstick tube. Ideally, I figured it would be a metal line that wrapped around the front or back of the engine. Then I would remove the dipstick tube and have a replacement made that had a T-fitting for the oil to return to the pan. I am really against the idea of drilling my pan, or otherwise removing it, because it is a HUGE pain.
The oil line that went to a banjo fitting into the drain bolt hole apparently was not the best solution either, but I am not quite sure why. It seems to me that it would have been the best solution. However, it was pretty messy to work with come oil change time. Andrew had one on his car and it just spilled oil everywhere when we took it off.
So I have not sourced any oil feed or return lines yet. As far as the 25 PSI, here's the quote:
Too much oil pressure can create problems with turbos. It is possible to force oil past oil seals that are in perfect condition if oil pressure exceeds 65 PSI to 70 PSI at the turbo. ... Problems of oil pressure overpowering the seal are evident in a frequent if not quite constant smoking problem."
Okay, so it seems I did not read it correctly - he also goes on to state (in a table)
Idle, hot : 5 PSI
Max load: 25 PSI
Idle, hot: .1 Gal/min
Max load: .5 Gal/min
So that means you need LESS than 65-70 PSI and you're okay. Now that I've read that twice
I am not worried. The Scooby puts out about 65 PSI at full RPM, right?
