I've just bought a turbo vent filter and fuel filter to replace the old ones, but cant seem to find the turbo vent filter. The car is a 2004 facelift freelander. I did however notice some oil coming from one of the screw holes, the left hand side one in the front engine cover. Is this normal? I removed the dipstic with the engine running, and no oil splashed out from there. I will put some pictures of the screw hole in question later.. I have reached right behind the engine on the left hand side (Standing in front) but cannot locate the filter anywhere, is it somewhere else on the facelift?
