Good value, does the job
This was recommended to me by a friend who rebuilt a Land Rover Diesel engine. I needed to remove the sump from my 2000 Reg Audi A4 2.5 TDi. Audi charge £35 for something similar but this is just as good, no leaks at all.Make sure both faces are smooth and clean, free from old silicone, clean with meths or similar, do a trial fit first before applying the silicone and use the correct torque setting.

Great Gasket Sealent
Excellent stuff, used to rebuild the sump gasket on my V6 406 Coupe highly recommended. Would advise to keep in a warmer environment before use, I left mine in the garage at winter and it too some force to get out of the tube.
