    NS Oscar 2 Group seal

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I'm getting an annoying small leak / drip from the portafilter (inside of collar and rolls down outside of portafilter) when pulling a shot.

    i thought I may have forgot to clean properly but clean as, changed baskets, then portafilter and all changes still have same issue in same spot.

    seen this small hole or gap on the inside edge of seal in the same area of drip. Is this small gap normal or did I wreak the seal/get a dud?

    A lot of group seals have 3 or 4 notches spaced around the edge. I couldn't see any others on your photo, but it may be normal.
    I would start by removing and checking it, ensuring there isn't anything caught underneath.

    Martin,

    Looks like you have a nick in the seal, and yes that is your problem.

    We are giving away 2 Oscar seals with every Eureka ATOM purchase, just in case you were in the market

    Cheers

    Antony

    Thanks Timmyjj21 looks to be the case as had a better look tonight and there is four notches spaced around the outer edge ridge. Might just buy a new seal in case.
