Ok there are two o rings in the water pump one keeps the oil from the timing chain side to come in the water and also keep the water/coolant separate from the oil side the second one keeps from coming out of the engine. i am sure the first o ring i talked about is pinched or damages or is not installed when the water pump was installed.

SOURCE: on my 2000 nissan maxima i just got the water pump

no, but they have to push in the timing chain tensioner in order to clear the water **** gear. It could be that there is air traped in the tensioner which should bleed out by it-self after running awhile.Or the chain was noisy before but you could not hear it because the water pump was possibly making more noise than the timing chain.

How to fix water going into oil on 1995 nissan

You might have a cracked timing chain cover, blown head gasket, cracked block, or bad radiator if it has a built in oil cooler. It's hard to say without a cooling system pressure tester.

Nissan maxima 2000. Oil dipstick level shows too high. Regular oil changes done and filter with proper amount added. White smoke alerted me to recheck things. Only thing I found was dipstick shows oil

If the oil level goes up, something has to be leaking into the engine oil pan.
That would either be gasoline from the injectors or coolant from the radiator. If you are not adding coolant, it could be a leaking injector.

Water getting into the oil pan

You have a MAJOR collant leak! This could be a badly blown head gasket,a cracked head,or a crack in one of the cylinder walls(not good).If it's leaking that fast,it shouldn't be too hard to find,but you're gonna have to take a lot apart to find it(unless you have one of those high-dollar fiber optic camera tools).Remember,water will go straight to the bottom of the oil pan(oil floats on water),so don't run the engine with water in the pan.(You WILL destroy every bearing surface in the engine,making a real good boat anchor out of it).

96 nissan maxima radiator cracked and water got into the engine how do i fix without replacing engine?

I think there is more than a cracked radiator, maybe when you ran the engine after you lost the water from the "cracked radiator", you cracked the head of the engine. This (could) let water into the sump, the water in the oil is not a problem, just replace the oil. But the head might need to be replaced if it is beyond repair.

Replace water pump 95 Nissan maxima

Remove the Old Water Pump
  • 1

    Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.

  • 2

    Place a car jack underneath the oil pain to support it. Also, to protect the engine parts, put a block of wood onto the jack.

  • 3

    Disconnect the negative battery cable and remove the engine mount and bracket on the right side.

  • 4

    Take out the drive belts as well as the idler pulley bracket, the chain tensioner cover and the water pump cover.

  • 5

    Push the timing chain tensioner sleeve up and put a stopper pin in it to keep it from slipping. Take out the chain tensioner assembly.

  • 6

    Turn the crankshaft pulley in a backward motion until it rotates 20 degrees.

  • 7

    Place 2 MB bolts into the threaded holes of the pump and tighten them by hand, alternating turning a half turn each at a time unit they reach the timing chain rear case. Doing it this way will prevent damage to the timing chain rear case.

  • 8

    Remove the water pump, throwing away the old o-rings. Make sure not to let the water pump hit the timing chair.

Install the New Water Pump
  • 1

    Clean all the mounting surfaces on the water pump and covers.

  • 2

    Install the new water pump with the new o-rings, tightening the bolts to 75 to 95 inch pounds (8.5 to 10.7 Nm).

  • 3

    Turn the crankshaft pulley back to its starting position (20 degrees forward).

  • 4

    Install the chain tensioner and water pump covers, tightening to .092 to 130 inch pounds (2.3 to 3.3 mm).

  • 5

    Take out the stopper pin from the timing chain tensioner.

  • 6

    Put a bead of liquid sealant onto the mating surfaces of the water pump and timing chain tensioner.

  • 7

    Install the timing chain tensioner with the water pump to the engine block, tightening the bolts to 87 to 113 inch pounds.

  • 8

    Add the drive belts, the idler pulley bracket and the engine mounting bracket with the engine mount.

  • 9

    Reinstall the negative battery cable and remove the jack from under the engine. Install drain plugs to the cylinder block.

  • 10

    Start the car and check for leaks when the engine reaches normal operating temperature.

Continue to monitor for the next few days for air bubbles in the system causing the fluid level to go down. NEVER TOUCH A HOT ENGINE, CHECK WHEN ENGINE IS COOL.
Good luck! --My Car Doc

Engine Heating

You need to replace the thermostat in the radiator, they are very inexpensive and most times you can replace it yourself, if that doesn't help, drain the radiator and buy a drain kit and radiator cleaner, it will remove rust corrosions and anything else blocking up the flow, replace fluids and check to see if it runs properly, worst case senario is that your water pump needs to be replace cause Nissans are notorious or I should say Older models are and water pump seems to be the thing that goes out before anything else

Leaking antifreeze

you need a water pump. water pump is inside the timing chain area/internal. the coolant is leaking out of a small hole behind the a/c compressor. water pump WILL fix it.
