Sorry, I have tried the search but I am on my phone and it is proving difficult or else I just feel too panic strike! Says it all in the title really, looks like it is coming from the black cover on the side. I might have a gasket set in with the spare wheel? It has only just started dripping having wound it up a step mountain this morning I guess and noticed it dripping when I pulled in the service station this afternoon. A) head home. B) Not worry and do an additional 600 - 800 this week and then head to the ferry sat for a crossing to Denmark. Then 1100 to St Malo. C) Have a go at changing the seals, if that is what it is? Only have basic tool. Nearest big town is Oslo 240miles away. Dripping about one drip every 20 seconds or so. Whilst I do not want to drop diesel in Norway the old mechical pumps on the Mercedes om636 actually had a connector to collect excess diesel as they wore. Feeling sick and grateful for any advice. Hope it makes sense as working on about a sq inch of screen. But up til now all good. Thank you.
