Hi, I have a 55 plate fiesta diesel duro tec , it has a nasty oil leak seems to be coming from back ov the head area , more so passenger side , it's not rocker cover , I just cannot see as too much stuff in the way looks near injectors quite a heavy leak , just wandering if there's a oil pipe or something known to fail , almost looks like headgasget , but head bolts are wet too so not sure ! Any ideas car has only covered 74k , seems to be a fair bit of oil in turbo pipes too , also anyone know the torque setting for rear wheel bearing ? Any help welcomed
