w211 E320CDI SUMP LEAK

[boxer 01]

Hi whilst carrying out oil service I noticed that oil sump is leaking. On closer inspection the seal seems to be some type of sealant I was wondering what type of sealant this is and whether it can be done by myself I would be grateful if any of the experienced members could provide a detailed procedure to carry out repair.
I have a roll of ptfe gasket material which is approximately 10mm round and on tightening will fill the seal gap perfectly but I am not sure how ptfe reacts with oil. I have only used on hot water/steam and it's superb (it's also very expensive.)
Regards

Thanks for the advice, just what I was looking for. What size tube, is 70mg enough to do one sump repair.

Yes you don't want to use to much and risk any sealant getting into the sump itself.

I was looking for oil to use after sump repair and I came across thisLook at this on eBay 10L Genuine Mercedes Benz 5W30 Engine OiL Low Ash SAPS MB 229.51 Fully Synthetic | eBay it's a merc dealer and looks the correct oil for my car and I am thinking of ordering just wondering if anyone else has bought oil off them.

Or 20 litres from MB Newcastle for £53-49, even cheaper. In my sump now.

Make sure there isn't oil leaking down the passenger side of the engine/gearbox.

Above the sump all-round dry and the sump gasket I was told needed doing a couple of years back. So the sump will be resealed soon and thanks for everyone's input much appreciated.
