Almost like you have an air leak at the block. Is that possible?

Al is pretty low, but Si that high is not native plus the Fe and Cu

I checked the engine and couldn't find any leaks in the block. just the hose on the air intake was loose. Will have to wait for next UOA to
see if that was the culprit.

Looking forward to any subsequent UOAs on the current engine.
