no, actually there was no apparent leaking at all, and the rubber was all in good condition with no visible defects, etc. Rather, the monovalve (~1 yr old) was stuck in the open position, but simply mssaging it (manually moving it in and out) unstuck it, and all seems to be well now. The wire coil around the valve was fine with an ohmmeter test, and current was going to the harness.

hopefully itll stay fine now, but I can imagine a sticky monovalve.

To my suprise, there was some orangish sludge on the screen element on the monovalve. I wiped it off, but wasnt happy to see that. I always get the dealer performed citric acid flush, somaybe its some leftovers, its almost due anyway (2 yrs this summer).

Thanks,

JMH
