Looked under the motor tonight as lost some oil pressure today ... looks like the oil filter might have come a bit loose looking at the residue around the seal(new one) so gonna get someone to tighten it propperly tomorrow. However noticed the rear diff was wet , looks lie the rear diff plate has cracked/perished.
So is there anywhere I could get one from or should I just go straight to a vauxhall dealer? Just read the post on "how to do it", also. Seems a farely straight forward job even for a novice

24 beers in a case, 24 hrs in a day...... coincidence ???
