« on: February 19, 2019, 08:16:31 AM »
I have a slight oil leak that i am sure emantes from the o ring between the head and jugs

Easy answer no BUT check the leak is not from an end cap area first

As Bryan said, impossible  ;D

Did you use a aftermarket head gasket and the o ring that came with it ? The Honda head gasket was 0.8mm thick and a lot of the aftermarket ones are 1mm. The problem with a lot of the aftermarket suppliers is they just used the data from Honda for the o rings and a lot are not thick enough to make a seal with a 1mm head gasket so, a upgrade is needed  ;)
