I was about to do it myself but the whole pan has to come off and its just too effing messy.So i rang a place in Campbelltown and i am so glad i did.
This is what they did for a hundred bucks( i provided my filter and gasket from "auto one" $17.) Firstly the guy reckons the cork gaskets leak, so they used thier own cardboard style(it clamps down firmer than cork).Ok they hoisted it up removed the pan,checked for bits n pieces of crap,cleaned it up,checked linkages and settings etc then put it back together,filled her up with oil took it for a test run then put the computor thing on to see if any faults were registered,lucky me all was ok. The job took about 1 hour and i watched em do it.So i suppose around 120 to 150 dollars is well spent if your lookin around.
