i have the 22r in my 84 pickup. it is leaking a shit load of oil and i cant tell where its coming from. its not leaking from the valve cover or around the spark plugs, but the entire drivers side of the engine block is covered in oil from front to back. and its all below the exhaust manifold. any ideas what could be leaking? also, there is no oil leaking on the pass. side of the motor anywhere....its all on the drivers side.
