Wayne,
attached is a picture showing how I worked around the issue.
The red line shows the
normal position of the line using the Boxster line as the 997 line would require a cut and connection of the Boxster line in another position. as you can see - it would go directly through the air/oil separator... which cannot be put elsewhere, nor could I use the Boxster separator which sits in an entirely different spot ( left front corner of the 987 engine) as the 997 does not have the connection below the separator where the oil flows back into the engine beneath.
The 987 engine has an electrical sensor (no sure for what ) sitting at exactly the place where the 997 has the separator - lucky I found the same sensor at the 997 engine not too far away, further on the left side on top of the engine case, so I was able to plug the cable in after loosening the harness less then an inch for that cable...
BTW - this was really the only connection where I had to loosen the harness a little bit, all other connections seem to be in perfectly the same place...
(of course I fit the additional VarioCam connectors on either side plus the Oil Pressure sensor in additionally)
The yellow lines show the piece of hose where I cut the line and fit a piece of hose in on both sides.... no better idea how to handle it.
My assumption is it should hold as the return line hopefully has very low pressure on it, the oil is just pumped back into the reservoir?
