My 96 windstar has been leaking oil ever since I got the right hub replaced. The oil leak is on the right side of the engine just near the oil sending unit... How can this problem be fixed?

Open up the bonnet and look for round black color device fitted near the driver side inside the engine bay. There will be pipes fitted to it and a brake oil reservoir on it. This is the brake master cylinder and round thing is brake booster. Any one of these is leaking and brake oil being very thin, is seeping inside your car. Take a look at the end of the pipes fitted to brake master cylinder, if anyone is leaking, tighten them. Still there is leak? your need to replace the master cylinder.

You have a front and rear main seal, if either of these are leaking the oil will be coming from the center of the engine above the oil pan. There are 2 1 in front and 1 in back of the engine.

Rate my answer.............Thanks

I just repaired a leak in my 1995 Windstar power steering system. The leak was toward the back of the engine but more toward the right (passenger side) of the car. There's not much clearance so I had to jack the front end up just to be able to look underneath. In my case the rubber hose had come off the metal tubing portion of the high pressure hose near the right wheel.

Fortunately, it had a screw type hose clamp, and barely enough working room, that allowed me to reinstall and tighten without having to remove the hose assembly. Yours sounds like there may be a break in the metal tubing, in which case the hose assembly would probably need to be replaced. Hopefully not.

Another thing that may come into play is whether the leak is on the high pressure side or the low pressure side. It seems that the high pressure hose assembly is long and winds in and around the engine. Probably a real dog to replace. Bottom line is you need to locate the leak and that will determine which hose it is and whether you need to replace or not.

I realize that this question is a few months old and has probably been corrected by now but, for others who may experience similar difficulties, have confidence, power steering systems aren't all that complicated and, usually, are not too difficult to repair. Hope this helps. - David

Can you isolate the oil leak a bit for us? If it is the rear crankshaft seal, that does require engine disassembly. The front crankshaft seal can be replaced with the engine in the car.

check the heater core supply/return lines. theres a steel tube which runs under the intake manifold which commonly rusts out.

if the oil is leaking when the vehicle is running the rear main seal ,between the engine and transmision is leaking. if not maybe there is a oil pressure switch at the back of the engine leaking ,or the valve cover gasket is leaking near the back of the engine , have the engine steam cleaned then you will see where it is leaking ,

did you check the steering pump, AC compression pump, etc or other engine components ? it could be something other than the engine.

Most possible oil leaks from valve cover rubber oil seal. Remove valve cover, inspect , clean surfaces, and replace with new rubber oil seal .
Good luck!
Thanks for using fixya.

You need to clean the engine and then run the vehicle while watching the area. The most common failure is the oil sending unit located near the oil filter. I have also seen a leak develop between the oil pump housing, which is mounted directly behind the hamonic balencer and the engine block.

ok who ever installed the oil filter didnt put oil on the seal and tighted oil filter down properly this lead to seal on oil filter burning up and cracking replace oil filter and put oil on the seal all the way around
