[Vwdiesel] Lorens specs toooo Stringent

The Haynes Manual is probably wrong on a lot of things.  Do yourself a favor
and get a Bentley Manual.

Now I'm all lost!
25.4 mm to 1"
1 thou = 25.4/1000
           =0.0254mm

1mm is 1/25.4  of1000 thou...
 or  39.4 thou

0.03mm is 39.4 x 3/100
or  1.2 thou

So the Haynes is wrong for piston to cylinder gap ...

BUT is a 1 thou gap correct?...  0.5 of a thou on the radius!!! or were the
conversions to imperial measure wrong from a metric engine...
Although in this case (haynes ) its the metric that I'd say is out....
Oh hell I dunno... This looks like an interesting debate that might get me
to change oil from the misers 'Walmart' brand to something decent... perhaps
my economy will go up from 69mpg imp to challenge Hagars 70's

With a gap that small isnt there a risk of seizure? Is this what makes lube
viscosity crucial?
