    I am trying to diagnose and increase in noise when driving. I am still not sure if it is engine or drive line related. I read through the Trabant buying guide posted on the forums and have tried to check for small end bearing wear.

    After taking out the plugs I rotated the engine and checked each piston in turn. If I move the piston in the cylinder nearest to the gearbox up and down around TDC so that the piston has just started to go down, and then push down on it using a piece of metal bar I get a small "click" sound. I cannot feel any movement I just hear a click. I checked that the bar was hard up against the piston before pushing down to eliminate the possibility of the click coming from the contact between bar and piston. The click seems to come from the top of the engine. The piston in the other cylinder does not produce any noise.

    Am I right in assuming that the one cylinder has some small end wear? Or is a little click normal?

    Could the click be indication of a broken piston ring?

    The only sure way to check is top remove the head and barrel then you will know where it's from

    I agree with Kev. Remove the cylinder. You can then check both, the small and big end for play. Lift the cylinder a little and stuff some rag in the case opening, in case a ring as broke and drops down when you lift the cylinder.

    @Andrewwoey Thanks for the tip about the rag. I have a set of gaskets for head and cylinders plus a piston ring compressor ready to go. I was going to do a compression test before I start dismantling anything just so I know what the start values were. I need my Dyane back on the road before I can immobilise my Trabant...
