Thanks for the input fellas, the search begins, my son who has now returned to Melb has informed me that when we trying to start her after the fuel incident he observed during one of her backfires a flame from the left side of the valley, if fire can get out air can get in.
Now for another little??? problem, when I collected her from Melb she had what I thought was a diff noise, came home (northern NSW) no worries just noisey. Had a couple of spare diffs in the shed from one of my earlier girls, knew both to be in perfect condition so swapped both, no difference, out with the LT230T (another spare for the shed) and in with a borg warner, noise changed slightly, higher pitch with a funny little warble at low speed on deceleration. Before the change I had considered the possibilty of planetery gears in ZF, but now the warble makes them seem unlikely????. Do torque convertors make strange noises??, the box does everything it should beautifully and she drives terrific, if a little loudly, keep the cd player volume up. All info greatfully accepted. Thanks Jhonno
