Default Leaking Clutch Fluid under transmission

Hello all,

I've looked around regarding leaking fluid from the clutch and initially thought it was the clutch slave cylinder. Finally I got under the car and saw something different. The fluid seems to be leaking from directly under the transmission from these two holes.

Anyone seen this before? The video/picture was taken with 10 PSI pressure from a Motive Pressure Bleeder. I don't want to replace the clutch master or slave before I figure this out.



At 25 seconds is when the pressure is built up to 10psi

Thanks for your help.

Just seeing the fresh brake fluid seeping in your pic, and not being able to view the video you posted, and that you didn't go above the recommended 15 PSI on the pressure bleeder and blow out the slave seals, I'd say fluid is getting past a worn slave cylinder diaphragm and exiting through the vent hole in the bellhousing.

This.

Your slave cylinder is shot.

Two 13mm nuts to remove it from the bellhousing.

I came across this problem as well, could it be the slave cylinder? There seems to be some pentosin on it and massive leak under the car, here are some pics

You have an E46 M3 with SMG. This is the E36 section. You could have a slave leak, but that mess looks like oil leaks from CPV, rear main seal, oil pan, etc.

I checked the CPV and there's no leak around it at all,
