Would someone in the know be kind enough to tell me what should the compression pressures be?
Also what's the range limit, 1 bar between highest and lowest is a typical figure - is this the same for rattly old VW aircools ?
Thanks in advance.

If mines getting 9.5 to 10 bar does that mean I've got a build up of pressure in the crankcase or is that something completely different and unrelated?

It means you have a good set of pistons rings and barrels
it's not connected

This thing, though the garage hopes to have another look today or tomorrow, at no charge apparantly
