Ive recently noticed slight leaking when Im pulling a shot from my silvia v2 and I thought maybe the seal is probably full of stale oil so I went out to buy the group head brush + clean machine powder + blind filter. (I bought the machine 2nd hand)
The story so far is, I back flushed 10 seconds on/off a number of times, gave the rubber seal a good scrub and now my silvia is leaking more than ever. It seems to leak more when I try to lock my portafilter in to a point where it is past the 6 o clock point(where the portafilter handle is pointing).
I seem to have cleaned the machine well but the problem is Im getting spraying water or water coming out of the group head leaking into my espresso.
Do i need to replace the group head seal?
How much would it cost and where should I bring it to?
Can I do it myelf? I cant seem to get the seal ring out of the group head to examine for cracks/damage. Some guides on the v2 would be nice.
Im considering putting in a PID on the v2, swapping out the steam arm to a v3 and replacing my rockys doser into a doserless chute. Buying a naked portafilter.
Its quite a number of jobs to be done, would be nice if Im pointed to a place near Hurstville NSW.

Id bet there is just a tiny bit of something up there which stops the seal going in flat.
