[Vwdiesel] Quantum Mileage Pre and Post Re-ring

[mark shepherd]

I agree Erik, it was a little poor. I've redone it, and added more info!

Excel 2000 doesn't seem to have a print screen function AFAIK.

One test I don't think I've ever done , is to measure a journey of pure 
75mph.

It could have done with a re ring years ago, but right up to the end, 
mileage wasn't that bad, even withthose ring gapsand 7 stuck rings lol. 
This particular engine reminds me of Lister/Petter stuff for chuntering 
along ability. I can't understand how come others seem to spend a fortune on 
these engines, and still walk around grief stricken!

Just one quick question - did you get that picture by using a digital
camera to snap a picture of your screen? It kind of looks like that.
You can get a much better image by pressing the "print screen" button
and then pasting the resulting picture into a picture editing program
and saving that. It will look as good on someone else's screen as on
yours when you were first looking at it.

Nice mileage increase! Makes it a little tempting to rebuild mine, but
it's still running so well, even with the high miles and burning some
oil..... :)
