Is the leakage serious? just make sure the oil dont kena your alternator and aircond belts, otherwise they will be damaged easily. Do check your engine oil level to make sure it doesnt decrease.
I was having leakage on my power steering hose too but my mech said the clip was loose, so he tightened it back and washed the stained hoses with petrol. He said drive 1st and see if it leaks again or not. Actually not leak but evaporate as claimed by him. But I just check the hose, there are signs on oil again...maybe time to change the hose. *sigh*
