hi guys just a quick question how hard is it to fit a oil pump in these engines,
iv got a 2002 wrx thanks

 

Quite straight forward to change the oil pump - remove the front pulley,outer cam covers,timing belt and crank sprocket(normally corroded in place).
There are 7 M6 bolts holding the pump in place.
You will need a Pump to Block O Ring and a crank seal if not already fitted to the pump.

thanks very much 4 your help
