Sounds like the valves are out of adjustment and this is causing the timing to be off. Can also be a blown head gasket causing this issue. I would first check the valve clearance and make sure they are both set at 0.005.

Is there any oil leaking onto the machine itself?

be more clear do not understand what you mean don't think there is any oil leaking in to the cylinder
I was asking if there was any oil leaking.
Are you familiar with valve adjusting?
