I have been having random bursts of white smoke (not at any time inparticular just completely random) so i thought i'd do a compression test. I did it a 5 times to get an accurate reason and the results are as follows:

Cylinder 1: 12 bar
Cylinder 2: 14 bar
Cylinder 3: 14 bar
Cylinder 4: 18 bar

I have a 1.6 corsa sport,

What does this mean, and why is cylinder 4 at 18 bar thats 260 psi, surely that is way off for a 1.6 engine.

Thanks for ANY advice

I had random white smoke on my XE. Got the head pressure tested to find the was a pin hole behind one of the valves.
