Oh noooo, sudden Pentosin leak ...

Sounds like you isolated the leak to "one plug", the plugs having the "big
X" on the flat top of each.  These are the cylinder heads of each pump
cylinder and are sealed by an easily replaced $0.10 O-ring.  They can fail,
sometimes in a year or so, if poorly lubricated during installation (a
typical rebuilder's problem).  This failure can also be aggravated by the
NO-NO of holding the rack against a stop when parking.

But, support your local wrench, and also give Blau another chance!
