Finally! I managed to get home before 20:00 and able to spend 40 mins playing with z before dinner time. I warmed the car up to temp and did a compression test using a Draper gauge. NB all plugs removed but the throttle was closed during the test.
The results have me scratching my head a little.
No.1 has the driest spark plug but shows the lowest compression of the lot - could it be valves not sealing well enough? I did the test twice to be sure the gauge was tight enough the first time; with near identical results.
The oily plugs are 3-6, yet the compression is higher than 1.
So, with your expert opinions, how do these figures fare and do they warrant a rebuild any time soon/show anything interesting? (Me being a geek excluded!)
Thanks in advance,
Ali
