Re: oil leak across front of car under front motor?
You really need to have a good look under it around the Exhaust pipe run. Usually this means putting it up on ramps.
I think for ease of diagnosis - go to a small garage and ask them for a quote for repair. Once it's on the ramps - have a look yourself.
If you think their quote is too high - get a second opinion, or if you are competent enough - do the work yourself. At least you will hopefully find the problem for free.
It can be as easy as a leak around a screw-on oil filter, or as complicated as a failed main crank seal - which often requires engine removal and splitting the gearbox off it.
Best to get a free quote anyway.

If it is engine oil leaking, it is coming from either the valve covers, the front seal at the timing cover, or the rear seal. You state that it does not leak when parked, but in most cases, the oil will continue to drip off the engine after shut off, and you will see oil spots on the ground below the car. The location should indicate where to look for the leaking area.
If the leak is not engine oil, it could be transmission fluid, power steering fluid, or even brake fluid. With the engine running, see where the fluid is puddling below the car. This will be a very good indication of where to look for the component that is leaking.
first check fluid levels --power steering--oil--transmission --if power steering low or out pump will sequel look for blown hose or seal----if oil is low or empty than look under around oil filter [hole damaged or blown gasket ] spraying on belt causing sequel if not filter than trace oil leak possible oil pan damaged or gasket crack or head or valve gasket-----if trans low or empty look at pan- gasket ,or damaged check trans cooling lines to radiator-----these are your leak areas under hood your oil pump is internal in oil pan and you usually dont hear it
I have not seen a power steering unit located on top of an engine usually they are on one side of the motor. I will need more info like is it drops of fluid or a spray pattern of oil or spatter???? where on the motor besides top is the oil top front top back??? Please don't take this wrong , I just have questions without seeing it its somewhat difficult to actually know what's going on with the oil and color of oil is it thin or thick fluid???
it could be a pump fault. have some one at the front of the car watching the pump. some one sit in the drivers seat and parked up start engine and wiggle the steering wheel left and right see how the pump is acting. engine revs should drop and rise when doing this if no drop etc then the pump fins inside are warn. If this is all ok jack the front off the ground and put on stands, turn the steering to full on each side at a time and check the steering rack joints and balls and the condition of the rubbers. look for leaks in the line wile you under there.
to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.
theres a number of places the oil could be comeing from oil pan gasket oil filter oil bolt front seal rear seal valve cover gasket as cars get older in time they begin to leak oil have it looked at by a trusted garage
it s acceptable in full lock to lock turns to hear the humming with normal wight steering and it is acceptable to drive the car without any power steering assist until have it fixed don`t be worry keep an eye on steering fluid
your rear main seal is probably bad. the reason it only leaks after sitting awhile is that the oil in the motor has finnaly all drained back into the pan and has hit the level of the breach in the seal
Put a clean piece of cardboard, thin plywood, or whatever, under front tires, large enough to cover area under vehicle from front bumper to just behind front wheels. Start it with power steering full & crank wheels back & forth a few times. Monitor for drops of fluid on surface, to isolate problem area. may need to sit all night. Or take it in to shop, have them put on hoist & diagnose.
