Oil Leak Fixes- Opinions
Check the pictures out:
    There is a small gear oil leak from the drain plug i will tackle later. The oil leak is on the left (driver) side and definitely makes its way to the exhaust. When the vehicle is driven harder more leak compared to normal driving. Also ticking noise from the left side (exhaust leak or valve ticking). Side notes: I have attacked the triangle of death in the past but still not ruling it out. Rms has been changed with latest Porsche part. Again, not ruling that one out either. Eventually i will find it but it would nice to bounce ideas and get some thoughts. Thanks in advance. Sent from my iPhone using Tapatalk |

Start with a can of degreaser and a water blaster, once its clean and oil free you will have a better chance of identifying where the oil is escaping. Gear oil can leak from the breather on top of the gearbox if its facing the wrong way. Other leak spots are the axle flange seals and the gear shift linkage.

Oil leaks can be likened to roof leaks... the drip is here but actual leak is over there. Will agree that only sensible way to track down origin is to clean it all up... and watch. Would not rule out any number of different locations being contributors.
Impact... would be good to know year of engine, mileage, and if rebuilt / resealed and when, etc.

85 euro 87k previously resealed incl triangle and rms as well as an oil return tube. Now i got me thinking about the breather valve on the transmission. I wonder if it is facing forward towards the front of the engine. Also wonder would that leak visually look like rms.

Varied opinion on what "front" of Porsche flat 6 is. To be on same page... let's agree breather hole should face front of car. Have heard when breather is reversed, it ejects "considerable fluid"---not sure what this means since I've never seen it for myself. Am wondering if it's possible to reach up to breather from under right side of car? I'm guessing it's possible.
Seems these two leaks would show differently. Breather oil would be evident running down sides of gearbox case. RMS would exit at bottom of bell housing... and spread out from there.

Following up on this. Removed airbox and afm and peaked into the backside of the engine to see if there is any leaks from the triangle, as I happily found the area completely dry.
Leak is making its way only on to the driver side heat exchanger. I am leaning towards rms or case leak here.... Any suggestions welcome. |

No RMS.
Extremely rare to have a case leak. You're going to have to pressure wash the underside and take a look for fresh oil. |

With all that stuff leaking, I'd just pull the engine and replace every seal you can get to - most everything can be addressed with pulling cams / rockers. G |
