I am sure that this can be repaired. The lid on mine was leaking. The
lid seems to be held on by a press fit with an O Ring and some glue.
Their are no cracks in the unit. What glue should I use to glue the lid
on with? Remember It must be able to take temperature fluctuations and
Pressure. Maybe the O Ring is supposed to keep the water away from the
glue and that has deteriorated allowing the water/coolant to attach the
glue making it a not so good a seal.:-(
Why else did the lid fail on mine? Have I got the right idea for the
purpose for the O ring?

Sorry about my attempt at drawing the WA but if you have seen it you
will probably recognise it - hopefully
