What you think? Im actually saving up for new pistons now.

 

The 2 cylinders which didnt go up much when oil was added I think was due to not enough oil being added into those cylinders. It was hard getting it to go through the spark plug hole.

 

 

What you do people thing? New pistons or just new rings? Either way I will have to strip the engine right down.

 

Would this bad compression on some cylinders be causing the smoke out of my exhaust?

 

 

Stuart

you need to add exactly the same amount of oil to each cylinder else the result will be missleading due to the oil occupying some of the compressible volume.

 

2 or 3ml from a syringe will do the job nicely.

 

4&5 do look a bit ringy though don't they.
