I have carried out a compresstion test on my 1983 1.2ST engine

The readings are as follows.

Cylinder 1 160psi
11bar

Cylinder 2 160psi
11bar

Cylinder 3 160psi
11bar

Cylinder 4 160psi
11bar

Are these right? also does anyone have the manufactures figures so i can compare.

I have also changed the spark plugs and the coil.

Thanks

They all equal each other (exactly, which is abit odd!) so i would be happy with those figures TBH. I dont have the standard figures. What did you use to measure them?

I used a compresstion tester bought from screwfix,Why is it odd that they all equal each other. i thought that would be a good thing.

Yes but exactly. No difference at all? .5 of a bar or anything, or was the scale not that accrate? It is good that they all match.

The scale was acurate, i was suprised it was spot on so i did a second test and it came out the same.
