Right took it out a few times this weekend and I can't see anywhere else where the oil is coming from at all, so it must be the headgasket. Can't understand what's happened tho.
one thing that did come to mind was after I snapped a headbolt I was so annoyed I just walked off and left it alone and forgot I left the head with the two middle bolts tourqed and the others just tight, for 24 hrs or so. Do you think this could have bananad the head at all. It was stone cold.
I have tried to google if alloy can warp when cold but can't seem to find anything on it.
other than that either it's detted and done the gasket or the heads lifted.
