Look to see if you have a leaky valve cover gasket near the inlet for number 2 cylinder.

I have read of oil leaking from the valve cover then getting sucked into the inlet port.

I think the guy replaced the engine before he discovered this... and he could have fixed it with just a couple of new gaskets if had spotted it.
