Hi Guys - I still have compression trouble but can anyone tell me what function the two socket head grub screws in the picture have ? They are in the central bay between the camshafts.
One is screwed in a lot more than the other. Never seen them on any other engine I've worked on.
Thanks for your help.
Dave.

My guess would be oil galley plugs, but I can't identify them for sure in my diagrams.
