I've averaged 18mpg on this run so far, Martin unfortunately had to leave the trip the next morning and head back to Sydney for personal reasons, I'm pleased and relieved to say all will turn out well.
Yes he managed to have the valve installed and it worked perfectly. We met up with Art Love in Albury in his white 6.3, which had shorted the cigar lighter and blown the short stubby 25amp fuse for the wipers. He called me from Moree and asked if I had a spare, I didn't but a quick call to MB Spares had 6 of them overnight to our hotel!
We are now in Mildura having stayed in Echuca last night, today was 4 and a half hours drive through some very remote country (relative), we avoided the major highways so a lot of it was on single lane paved roads in the middle of nowhere, with no phone reception, 2 children under 10 and a 45 year old car.
I think foolhardy is a better description than brave. Needless to say I scanned the instruments constantly but Six 3 ran perfectly, A/C on the whole way and instruments rock steady. I have a renewed appreciation and enthusiasm for my car
I shall start a new thread with pics and a story on my return. Broken hill tomorrow up through the outback
