Hey folks, fitted m20b25 this weekend... started it up developed low end knock... after while oil pressure came back and knocking stopped.. i assume it was a sticky oil pump.

Now it has developed a knock from the top end... on start up and idle is when u hear it at its worst and the exhuast has started to develop oiley smoke out of the exhuast...

Any idea's what its likely to be ?
