Is it possible for power steering fluid to get into the engine and mix with the oil? I am loosing fluid and there are no visible leaks, the engine oil and filter was recently changed and now has turne

Put card board or news paper under you car. Leave it over night. You first want to determine if you are leaking engine oil...Transmission fluid or Anti freeze...or power steering fluid also.
Check all of your dip stick levels and read your owners manual...it is always vital in finding leaks and types of fluid you maybe leaking. OIL is dark....Transmission is red and some power steering fluids are more clear/cleaner. Also Anti freeze is a greenish color and smells sweet like freshely cut wood chips. GOOD luck..always start with the basics.. One drop of fluid on news paper can make it swell up to about the size of a 50 cent piece.

PS fluid cannot possibly leak into the engine oil. They are completely separate systems isolated from one another.

The only fluid that can leak into the engine oil is radiator coolant via a crack in the engine block or engine head or via a damaged head gasket.

On cars with automatic transmissions, there is normally also a separate circuit for cooling the transmission fluid built into the radiator. The oil from the transmission is pumped by the transmission through a second heat exchanger inside the radiator.
This is a separate system but if there is a crack in the radiator where the transmission fluid is cooled it is possible for auto transmission fluid to get into the radiator coolant via a crack in the right area. If auto transmission fluid has got into the coolant an inspection of the coolant will show it.

Might you have an automatic transmission?
Automatic transmissions have their own dipstick.
I don't know about Aussies, but here in the states, transmission fluid has red die added to it to prevent your mixing them, and to tell you whether it is engine oil or transmission fluid that is leaking.
If you mix them by mistake, you must drain them and put in the correct fluid, or suffer ruining the engine or transmission, which ever one has the wrong fluid.
Your oil light should not be coming on. That is a different problem.
Oh, yes. There may be a dipstick on the power steering pump it you have power steering, but it should be really small. (short)

Hi there? the oil leak that you getting on your pedals is not oil, it's brake fluid from the clutch slave cylinder. has the clutch pedal operation changed lately.
You have to replace it because it will break down soon.
Good luck.

Your problem could be a pressure side hose that has a rupture that only leaks in extreme conditions. Inspect to replace with new to repair problem. First make sure you have removed the pump caps off of the hose fittings. If ok, it appears you may have a stuck valve in the rack assembly. Replacing the rack should solve your problem. ------- The new pump should be self-bleeding by turning the wheels left and right. Let sit over night to release air bubbles, recheck fluid level.------ Check the tension of the drive belts on the pump, as they may be loose. The power steering pump and reservoir is located on the front of the engine driven by one of the fan belts. There is a removable cap on the top with a dipstick attached. With the engine off, fill this up to the full mark with power steering fluid. Replace the cap, start the engine and check for leaks. On the back of the pump are two hoses either one could be leaking. REPAIR PROCEDURE:
1. Wipe the power steering cap and area free of dirt. Remove the power steering cap.

2. Use a siphon pump to remove as much fluid as possible from the power steering fluid reservoir.

3. With a helper in the vehicle, raise the vehicle on an appropriate hoist.

WARNING :POWER STEERING FLUID, ENGINE PARTS, AND THE EXHAUST SYSTEM MAY BE EXTREMELY HOT IF THE ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES OR POWER STEERING FLUID TO TOUCH HOT EXHAUST MANI FOLD OR CATALYST. 4. Locate the power steering cooler attached to the crossmember support plate. Slide back the clamp and disconnect one of the two power steering return hoses at the power steering oil cooler and drain fluid in an appropriate container.
5. Have the helper turn the steering wheel back and forth quickly several times to force as much fluid as possible from the steering gear.
6. Reconnect the hose at the oil cooler using the original clamp.
7. Lower vehicle so the vehicle tires are not contacting the ground. 9. For proper fluid fill and bleeding air from the power steering system:

a. Fill the power steering reservoir to the top of the fill range using Mopar power steering fluid (ATF+4) p/n 05013458AA.

b. With the engine OFF and the vehicles tires off the ground, slowly turn the steering wheel back and forth (lock to lock) slowly 20 times to force fluid into the steering gear.

c. Fill the power steering reservoir to the top of the fill range.

d. Start engine and let run for a few seconds, then turn oft engine.

e. Check fluid level and add if necessary.

f. Start engine, and slowly turn the steering wheel lightly contacting the left and right stops.

g. Stop the engine and check fluid level. Add fluid if necessary.

h. Lower vehicle, start engine and slowly turn steering wheel lock-to-lock.

I. Stop engine and check fluid level. Add fluid if necessary.

j. If fluid is extremely foamy, allow vehicle to stabilize a few minutes, then repeat steps "i" and "j" until the fluid level remains constant after running the engine and turning the steering wheel from lock to lock.

10. Inform the vehicle owner/operator that a steering vibration may be noted for a few hundred miles until the air is completely removed from the steering system. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Check up the hydraulic power steering pump.
See picture below for 1.6, 1.8 liters Audi (4 cyl.) engines:

If you find leaks and noise when runing, the hydraulic vane type pump is damaged. The pump **** air inside and mix air with oil resulting foam. Therefore fluid volume inside steering instalation rises. Then pressure overflows oil from the reservoir. You need repair or replace hydraulic vane type steering pump.

The redish orenge liquid you see is likely power steering fluid.

The power steering circuit is leaking somewhere.

Inspect/have the circuit inspected looking for busted hose, loose clamps or steering rack leaking.

Depending if the leak is severe or not you can try to add power steering oil in your power steering reservoir up to the right level indicated on the stick. Put the cap in place, start the engine and turn you steering wheel few times gently going from one extremity to the other and reversely. After few times you should/could have recuperated power. However, eventhough it works, for your safety fix the problem as soon as possible.
Hope it will help

the sound you are hearing is the pump running out of oil. if you continue to run the engine without power steering fluid you will damage the pump. the best thing to do is to top up the power steering fluid and have the leak fixed as soon as possible. paul

Yes There Is ONLY ONE PLACE for Power Steering Fluid.

ZF Gemmer Steering

The ZF Gemmer steering is permanently filled with oil. There is no drain plug.

ZF Rack and Pinion Steering Without Power Assist

The ZF rack and pinion steering is lubricated for its service life and therefore does not require servicing.
In case of repair, steering components on E21 vehicles are to be lubricated with a sodium-based grease, with a temperature range of -30°C to +75°C .
Calypsol D 4024 BMW Part No.32 11 1 116 929

Ball and Nut or Rack and Pinion Power Steering

Only reputable brand Automatic Transmission Fluid (ATF) of Dexron® III formulation may be used for the power steering and power steering pump.
In case of brief hydraulic noise after starting at low outside temperatures, we recommend replacing the red ATF with green CHF or LHM oil (see below).

ZF Ball and Nut Power Steering with H31 System

The approved oils for BMW models with power steering and the H31 brake booster system are identical with those oils approved for power steering without the H31 system except for the following:

E32 models with self-leveling rear suspension and mutual oil supply tank in the engine compartment.
Countries with very low outside temperatures (e.g. Canada) had their power steering systems filled at the factory with Pentosin CHF 7.1 since 9/87 through 9/91. This is also to be used on vehicles built before 9/87.

Since 9/91, vehicles now use Pentosin CHF 11S instead of CHF 7.1.

Pentosin CHF 7.1 BMW Part No.81 22 1 468 879
Pentosin CHF 11S BMW Part No.82 11 1 468 041

These cars are marked with a pertinent label located close to the oil tank.

LHM oils (green color) of the following manufacturers may also be used instead of Pentosin (CHF 7.1):
Shell LHM
Castrol LHM
Exxon LHM

The mixing of CHF, LHM oils and ATF is not permitted.

Pentosin CHF 4548 was used on vehicles built before 9/87 but is no longer available. However, mixing of Pentosin CHF 7.1 with residual quantities of Pentosin CHF 4548 are permiffed in these earlier vehicles. Mixing of these two oils is not permitted for E32/E38 vehicles.

The hydraulic system for power steering and power-assisted brakes must be drained as completely as possible when changing from one type of oil to the other.
All oil supply reservoirs are marked with the type of oil being used - ATF or CHF.
