Hi Seagull, Thanks for your help that sounds pretty straight forward. When I finish cleaning them should i replace the injector O-rings?
I checked the code on the diff and it is fine. The good thing is that my impreza was Auto and the aust autos came out with a 4.11 on the 1800, and the jdm M/T Code says that it is a 4.11 . checked both codes against spec from factory manual so should be fine. rear diff code was (VA1REE-XA) front was( EF-TY752VB3AA.
Cheers Clive
