A short while ago I posted a thread about building a leak down tester so thought I would show it in action on a Renault 807-10 motor.
Last November I did a compression test on said motor, these are the results.
Cylinder PSI Dry PSI Wet
1 115 130
2 117 125
3 118 126
4 117 130
I have attached some pics of the leak down tester to compare with the compression test
