I did post a link (above) regarding the highly technical aspects of honing and ring chatter but from the responses afterwards figured it hadn't been widely read...These last posts confirm my suspicion.
Even if the honing angle is wrong surely it is the same in all four cylinders - or is it? Clearly something is different in that one cylinder that is oiling. Is there any possibility one cylinder was honed at a different time or setting to the others? Maybe the honing angles should be checked?
