i have a 2wd cossie and i have notice a oil leak i first saw a bit of oil on the boost pipe the 1 where the air filter attaches to it didnt seem to get worst and i couldnt trace the leak i then used the car and as you do gave it a bit of stick i came home and it was really bad oil had chuck up onto the drivers side inner wing and it was also on the bonnet it appears to be in a straight line across the bonnet which suggest from the front of engine so i steamed cleaned the engine and ran it upto temp then reved it hard but cant see a leak its mu8st be coming from the front of engine presume its the exhaust side as the inlet side is dry and no oil was there and must only be when under a heavy load as in driving any help much appreciated cheers
