So I topped it off, and even put a bit more over full since it was more than halfway it's life span and will burn oil. Told my bro to put a piece of cardboard under where the engine is to see if it leaks. Anyways a week later, he told me that there was no leak present, check the oil level, it was at the half mark on the stick. WTH, one week, one litre gone, no leak? I highly doubt an engine can burn that much oil in a small amount of time. Can you guys come up with anything, I'm stumped...

can be leaking from the valve cover somewhere right onto the exhaust manifold.... meaning it will only leak with the engine is runing and the exhaust would burn the oil off possibly unseen.......
