The big end shells had the necessary hole in them to supply pressure fed gudgeon pin but as I replaced with splash fed gudgeon pin arrangement this was rendered redundant. The small end bushes were drilled with an extra hole to allow for the small oil reservoir. Ive had the sump off and opened the big ends. I couldnt detect any small end play.

Ive heard of some of these rebuild kits not allowing enough oil to the rings. In fact someone recommended leaving the lower oil control ring out of the engine altogether as it would allow better liner lubrication with no effect on oil consumption.
