main oily bits on the back of the engine are the oil pressure sender (7 and 9), on the front bank, and the vtec solenoid units (1) on both banks.....

the other traditional place to leak is the 4 (2 on each head) 'cam plugs' which are 4 rubber bungs that seal the holes needed to machine the cam journals... the bungs get old and hard, and eventually fail
