check for hose splits not just hoses blowing off.
haha yeah I found a old post from you that described that, which is what caused me to start looking there. BTW what grease do you use on the inside, and also do you have their number? I cant seem to find a US website for them.By the way, that is exactly what happened when my Forge BOV got stuck open on the way home from Carlisle last year. The car started to lose power then it completely died. I could only keep it alive by revving it and barely made it back to the gas station. Turns out the secondary spring failed and could not close the diaphram completely.
