Porsche **only** used the oil pipe on the left for the M97 2.7 and 3.4 engine in the 987 and 987C
The M96 3.4, 3.6 and the M97 3.6 and 3.8 utilize the same oil return pipe as the 2.5/2.7/3.2 Boxster engines.
What gives? Why change only on the mid engine late cars?
I know what it does.. and I know which one **technically** should work better
Anyone out there "know" why they did this?
