Just given Hana a run... how? Hmmmm! I popped the "hood" this afternoon and started her up (she still does that just fine) and decided to have a root around for these mysterious vacuum hoses (to block)... and what did I find? Well.. not all of it but most! Darren said I was missing a delay valve and unit but I'm not.. it's right there - just unhooked. I plugged everything back together and then suddenly the engine note changed considerably! I took her for a run without hitch too.. drives the same way she always has. I am missing at least ONE hose.. I do not know which and I have no camera to take pics to show you guys.. however, I have blocked off what I can and the hissing has stopped. Not ideal, but it WORKS. If those galant guys, Martin, Mark, Claire etc still want to help me out with the "reconstruction" then I'd be most grateful - but for now it appears Hana is once again roadworthy... Phew... (with the sun out I couldn't resist!) Now going back out to wash her... first time since Bath! Dan Vin#5284 - Hana (patched up but still poorly)
