Hi All,

Just been out in the 996.1 C2 and when I got back and was parking in the garage, I noticed a tiny amount of oil on the floor under the Turbo S.

After further investigation it looks like the tiny oil reservoir, under the drivers side Turbo, is leaking from the hex-plug.

Should I just nip it up, and drive it, or could it be more serious?

Probably no more than a half a thimble of oil.

Photos attached.

Clean it and then go for a drive. Come back to it and see if you can trace the leak. Once you can be reasonably certain where the oil is coming from then fix that. It may not be the sump plug.

I'd bet on a pipe leaking but as above wipe it off and go for a drive.

That looks like the pipe rather than the hex plug to me. But as above.

To me and i'll agree with the above .. i think it's the pipe ..

Can i also just say .. that's not a leak .

At best that's a sweat and not worth trying to get that pipe out and replace it .

10 litres of oil aint suddenly going to gush out from that .. obviously if you want to fix it then that's fine .. i'm just humbly trying to point out its not broke and as such doesn't need fixing atm Smile

Just to echo what DeMort is saying, ive just had all that stuff off and if yours i similar to mine that pipe connector will be absolutely solidly corroded into the sump.

At that point your only option is to cut and replace the whole pipe along with all the oil that comes out.

Those pipes vary in price between £130 and £170 each.

Could give the pipe a tweak with a spanner and see if it feels like it will move, if not give it a wipe and keep an eye on levels
