Compression Motor F8Q

I need if someone has the compression in bar or psi minima of the F8Q engine, because it was done again, everything, and vents worse than when disarming it. Thank you.

New F8Q engine that develops 65 hp. This engine will also equip the Clio I and II, Express, R21, Kangoo, Megane I and Traffic I. A 55 hp version will appear in the 90s. The first generation of the F8Q engines continues with the problems of a cylinder head and butt joint of the second -generation F8M engines. I recommend you to advise you in the opening of the camshaft, when compression
as a general rule to determine the compression that an engine must have, when it is not specified by the manufacturer, it is taken and value of the compression ratio, so if the compression ratio is 9: 1 (9 to 1) the pressure value must be 9+1 = 10 bars.
Conversions

to convert from bars to PSI (pounds of pressure, as it is commonly known) is

necessary 6,8947 bars so that compression can be considered as normal, the difference between reading a piston and another should not exceed 10%. If the difference is greater, the following rules can be applied: low -cylinders compression can mean that a washed cylinder problem. This means that the engine has injected too much fuel and has washed the oil from the cylinder walls. The oil creates a sealed effect between the piston, the rings and the walls of the cylinder. Without this fine oil layer, engine compression escapes towards the crankcase.
