Why is sods law such a git. Decided to keep my mv6 so put new tyres on her, stainless steel system from longlife (nice and shiney) then hey-ho a leak and a light. Can anyone suggest before i start looking . The oil light has come on but only when idling so got it home and parked. Checked in engine bay to find oil on lower tray. Oil a bit low so topped it up, cleaned oil and ran for a little time. Evidence of leak from somewhere at the front, perhaps lower parts. What am i looking for which could be the most obvious.

Thanks for any help.

oil pressure switch is down the front just to the left of the crank pulley as you look at it from the front,worth a look as it may be why oil light coming on

Thanks for your responses. Sunday is inspection day.
