Piston rings gone maybe?

[Hunty]

My starlet has being letting out blue smoke quite a lot so I've done a compression test today and the results were 170 120 170 170 could this be the piston rings?

Thanks

Doesn't sound too great, first instinct with those readings would be ringland damage.

Doesnt sound good or look good on the cylinder 2 .. ONly really know once you have it apart but could be rings or the lands as above

looks like it buddy have to take it apart to see

[starletburkie]

ringlands i would say as the rings dont go like that

yeah rings would tend to usually wear fairly evenly across the cylinders although they could have been dodgy.
