I've got a oil leak on my valver (20EX). It looks like its coming from the oil filter housing or maybe the sump, cant see which. Is it possable to remover the oil filter housing (including the thermostate for the oil cooler) without having to remove the whole oil pump? if so, how? i cant see any bolts that might do this, but it does look like it should be removable.
Haynes doesn't really say.
I've bought a full bottom end gasket set but if i have to take off the oil pump to fix it , i'll have to half drop the engine out i think (cam belt off etc etc) cause its in a nova.
