Useful info (images don't work though
) specifically: JayGenerally a difference of more than two Bars between cylinders can indicate a possible fault.
The first test compression was higher than the following recordings. This could indicate a carbon build up on the piston or another possible fault.
The quicker the compression builds the healthier the engine.
If the tester shows a slow rise in pressure or jolts up progressively on each compression stroke (you may need a helper to observe the reading) this may indicate cylinder bore/ring damage or leaky valves.
