Mine lost 50 and 30mm on the front last night over 15hr so a new valve block is on order.

New valve block has cured the issue. Very Happy

Prior to changing I could hear the old valve block "gurgling" (once the engine was switched off) as the air was bypassing the seal. I've yet to take it apart as I'm waiting for the vacuum tester to arrive.

Well I'm not sure if I'm doing it right. But here goes.

Sealed off the inlet and the rh side and put the vacuum on the lh side feed. (dropping most on this side). Can visibly see the gauge dropping (slow; maybe 0.5bar in a minute). So I thought maybe its a pipe connection. Placed Air valve block in water (no leaks). Gauge still drops. Cant believe it would lose so much so quickly although I am working the opposite way to the valve.

Car no longer drops on the front. The rear is now noticable again (over 3 or 4 days) so will order a rear air valve block
