sounds like you have the KA-E Head tick issue too. I am biased against the SOHC engine having worked on a couple of them myself.

If you just wanted to fix the oil problem, you could try swapping spark plugs to see if the problem is the thread on the plug or the hole... even then, that oil might be (probably is) in the combustion chamber, thus calling for for a head swap.

Considering the price of some KADE engines, I'd look into swapping for a DE. But do your research on the swap!
