If it's way past the normal lock-in position, you can add a shim gasket underneath the grouphead gasket (pre-made for common group sizes, otherwise you have to make your own).

Thanks Dan.

So my PF locks in at a normal position at a little past 6 o'clock between 6 and 5.. There is wear as the machine is circa 1984.

I think the OE gaskets will work as I had that in the machine before and never had a leak until recently when they needed to be replaced. I measured the OE gasket versus the Olympia gaskets and they are indeed thicker.

Hopefully they aren't different otherwise a new group it is
