would 4 tenths of a thou be possible in a mass production engine?

Looks like the Rave manual is wrong

This is my calculation in converting mm to thou

0.01mm 3.937007874 thou
0.048mm 18.8976378 thou

your out a decimal place on both your calculations, round it up and you get what the Rave manual says. by your calculations it would be 400 thou to a mm.

Don't laugh but i've just found some 20w50 oil in Wicks! I had to buy some in the name of research of course! Anyone know who makes Wicks oil?

Asda own brand 20w50 is about £5 for a 5 litre can

Good for flushing stuff through I reckon.
