(bad rings on the pistone)

i would have oiled the threads putting them in...it wouldnt hurt anything..news

I had the same problem, it is most likely a very small leak in the valve cover gasket. If it doesn't fill the spark plug hole I'm not going to worry about it too much. You'd have so much BLUE smoke it would look like a fogger if you had rings so bad your threads were coated in oil like mine were on cylinder 1.
