The pump is leaking some gray fluid

Gray fluid is usually indicative of old oil with water mixed into it. First you have to determine if the fluid is coming out of the motor or pressure pump. Then change the oil in that, or both, and then watch the condition of the oil when you use the washer. With new oil, it won't turn gray but will get a milky coloration to it. There shouldn't be any way for water to get into the motor oil short of the engine being sprayed directly with high pressure water. If water is getting into the pump oil you'll have to check the seals inside the pump.

Is there a weephole for oil and one for antifreeze or just one weephole for both on the water pump of 2005 ford taurus

It is very unusual for oil to run from a water pump, but you can get a leak from the grease that lubricates the bearing. If you do have what looks like oil or grease, you probably need a new pump.

Water in oil put new motul 7100 in and rni it for 10 min and drop the oil and it comes out grey???? o8 rmz450

The seal in the water pump has gone bad and is letting water get into the oil. The oil turns grey when water gets emulsified with the oil. The pump will need a new seal, "O" ring and gaskets. Go to this website to see an exploded view of the pump assembly; tombones49_289.gif

I suspect the water pump needs replacement, since there is liquid like fluid below engine. what are the steps one must take, to replace the water pump. Why is it not simple to do? Looks like alot of...

1.3L & 1.6L Engines
  1. Remove the timing belt cover, timing belt, tensioner, plate and spring.
  2. Remove the water pump mounting bolts.
  3. Remove the one (1.6L MFI engines) or two (1.3L and 1.6L TFI engines) small rubber seals from between the water pump and the oil pump, and the water pump and the cylinder head.
  4. If necessary for clearance, remove the oil level dipstick tube retaining bolt from the engine block and the alternator adjusting brace.

Do NOT use a prybar between the water pump housing and the engine block to separate the two components; this can cause scratches and/or gouges, which can prevent proper sealing.

  1. Pull the water pump off of the engine block. If the water pump is difficult to remove from the engine block, use a soft-faced mallet to tap the water pump housing until it loosens.

Do not disassemble the water pump; if the water pump is damaged or defective, the entire unit is replaced.

  1. Thoroughly clean the water pump gasket mating surfaces of old gasket material and corrosion.

The drive belt can be used to hold the fan stable while loosening the mounting fasteners

Loosen the fan bolts, then either remove the drive belt before the fan and shroud ...

... or wait to remove the belt, along with the water pump pulley

Once the cooling fan and shroud are removed, access can be gained to many of the engine components, including the water pump

To install:

  1. Along with a new gasket, install the water pump on the engine block. Tighten the water pump mounting bolts to 88-115 inch lbs. (10-13 Nm).
  2. On 1.3L and TFI 1.6L engines, install two new rubber seals: one between the water pump and oil pump, and the other between the water pump and the cylinder head. The MFI 1.6L engines only use one rubber seal, located between the water and oil pumps.

Be sure to install the two rubber seals between the water pump, oil pump and cylinder head before installing the timing belt cover-1.3L and 1.6L TFI engines

The 1.6L MFI engine uses only one rubber seal between the oil pump and water pump

  1. If removed, install the alternator adjusting brace and the oil level dipstick retaining

Pump oil seeps out of its fill cap.

More than likely you have water leaking into your oil, making the oil float on the top and out of the vent. Eventually you'll only have water, and no oil. Drain oil and replace. You will probably have to replace the seals between pump and crankcase. Only remove front of pump,(brass part) if you catch it in time the bearings in the rear portion won't go out. Do it now before the water wears the pump out. You can get parts for most pumps at Or go to Hope this helps.

Water getting in to engine oil i think head gasket in fine ive been told i may have a problem with the water pump is this true?

The water pump oil seals, yes. The seals keep the gearbox oil separated from the water. The only other way water can normally get into the gearbox is if you have a cracked center casing, a loose oil filler plug, bad head gasket, bad cylinder gasket, and condensation. The normal culprit is the water pump seals.

Had water pump changed on 2003 Highline Jetta 1 month ago. Oil cooler had to be replaced 1 month later. Oil landed up in water - oil totally empty. Temperature gauze said "Check coolant". Muddy consistency...

sorry to be the messenger of bad news but from the symptoms described it sounds like the head gasket ,the oil feed to the camshaft to be more precise ,its forcing oil into the water circuit but the water is not getting into the oil because its at a lower pressure .
