No, if thers water in the cycinders it will be the head gasket.

I have water in the engine oil. Could it be a water pump seal or a blown head gasket?

When you say that you have water in engine oil, do you mean that you have coolant mixed with oil ?
In order to determine if it's a seal or head gasket, you will need to perform a few tests. Cylinder leakage test on each cylinder can be done to determine if the head gasket is bad. When it comes to the water pump seal, if this was the problem, the coolant would not be mixing with the engine oil.

My 2004 PT cruiser have a bad water pump fill it with water going about 70 when white smoke came out then it rattle and shut off now it wontstart

That is bad news, sorry to say. Much worse than a bad water pump, white smoke is an indication of coolant being burned in the cylinders, probably due to a cylinder head gasket failure. To verify, have an engine compression test done, or pull out the spark plugs and check them. The bottom part of the plug from a good cylinder will be tan or light brown with very little deposits on them. A bad cylinder will likely have a lot of deposits on the plug. You may even see evidence of water in the cylinder. The only repair is a new head gasket, which gets quite expensive at shops. It is a labor intensive job, not terribly difficult but takes a good amount of time getting to the head gasket, and a good shop will check out the cylinder head for cracks, for straightness of the head where it sits on the engine block, and if the valve train is still good or needs any new parts.

Water pump is boiling on a 1999 CADILLAC DEVILLE but car drives okay vibrates a little

water pumps do not boil but engine coolant systems do from lack of water . Water pumps leak and get bad bearings but the heat comes from blocked radiators-blown head gaskets--cracked heads --fans not working and the vibration is from pistons and rings trying to bind up in the cylinders from over heat situation

Leaking coolant

If the water pump was bad, it would either leak water out the front of engine from the pump (bad seal inside the pump), or it would not circulate the coolant through the engine and the radiator (bad or worn pump impeller blades) but then for sure, the car would overheat.
Where was the smoke coming from, the exhaust or the engine area? If it's from the engine area, the coolant was probably leaking on the engine and then boiled away. If you had white smoke from the exhaust, coolant is entering a cylinder from a head gasket leak and being burnt off inside the engine.

2004 vw touareg 2.5 tdi the oil sump was full of water and oil mix,also inlet manifold had oil and water mix.number 5 cylinder had locked up and engine would not turn,so i removed glow plugs and cranked...

Can not be water pump, because that has a vent hole to the outside, and does not at all allow access to crankcase or cylinders. Oil cooler is also unlikely because oil is under more pressure than the water, and it would not get into the cylinder.
Water in the cylinder means up high.
That means head gasket or cracked head.
You can tell with a leak down test.
You borrow the gauge from a place like Autozone, and replace the water reservoir cap with it. Over pump it, about 30 psi. And watch for leaks. If same cylinder keeps filling, then you know where the bad gasket or head crack is. Diesels often crack heads. Not hard to do, but new head is not cheap. Probably $500 for part, $400 labor.

Water pump removal

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old. 1.8L Engine
  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the timing belt.
  4. Raise and safely support the vehicle.
  5. Remove the engine oil dipstick tube bracket bolt(s) from the water pump.
  6. Remove the two bolts and the gasket from the water inlet pipe.
  7. Remove all but the uppermost water pump mounting bolt.
  8. Lower the vehicle.
  9. Remove the remaining bolts and the water pump assembly.
  10. If the water pump is being reused, remove all gasket material from the water pump.
  11. Remove all gasket material from the engine block. Fig. 1: Exploded view of a water pump mounting - 1.8L engine 86753048.gif
    To install:
  12. Install a new gasket onto the water pump.
  13. Place the water pump into its mounting position, then install the uppermost bolt.
  14. Raise and safely support the vehicle.
  15. Install the remaining water pump mounting bolts and tighten all bolts to 14-19 ft. lbs. (19-25 Nm).
  16. Install a new gasket onto the water inlet pipe.
  17. Install the two bolts from the water inlet pipe to the water pump and tighten to 14-19 ft. lbs. (19-25 Nm).
  18. Install the bolt to the engine oil dipstick tube bracket.
  19. Lower the vehicle.
  20. Install the timing belt.
  21. Fill the cooling system.
  22. Connect the negative battery cable.
  23. Start the engine and allow it to reach operating temperature. Check for coolant leaks.
  24. Check the coolant level and add coolant, as necessary.

Changed bad water pump and timing but car is still overheating causes

Overheating is not always caused by a bad water pump or bad engine firing timing.

The most common causes are:
  • faulty radiator cap: steam/water will be escaping from the caps when engine is hot or oveflow tank overflows or empty!
  • crack cylinder head gasket: check when engine is cold thru radiator cap hole for milky oil in water radiator or large bubbles in radiator water after starting engine. Also check if water steam comes out of exhaust.
  • cylinder head itself: same symtoms as for gasket above.
Hope it helps you find your problems.

My Golf suddenly now starts to overheat badly, and although the oil buzzer goes off, the temp buzzer stays quiet. It's full of oil, and antifreeze.

Hi could you try doing this:
get the engine warm then turn the heater on to its hottest setting then turn it on, if you only get cold air then this points towards the thermostat staying shut and if this is the case it will need replacing before you do any damage to the cylinder head and or cylinder head gasket.

if you have hot air coming out the the problem could be one of the following problems.
1, check for any signs of leaking coolant if you have a leak then this lets air into the system causing an air lock this stops the water pump pumping the coolant around the system and this prevents it from cooling, the leak could be either split hose, damages rad or leaking water pump so have a good look around all the engine and pipes looking for leak, the water pump is located where the timing belt is so have a good look around here.
2, water pump could be damaged and may need replacing.
3. worse case you head gasket could be damaged, if you find no leaks ant the thermostat is ok then your going to need to get the head gasket checked your car will need taking to a garage to have a color test done this checks the coolant for signs of engine gasses and if they are found it indicates head gasket failuer.
it will cost next to nothing for them to do this test.

if it is the head gasket then you need to find out what caused the head gasket to fail, it could have failed on its own or the water pump or thermostat could have caused it to fail.

check the oil for signs of water if you have a white substance if the oil filler cap then this is a sign water is getting into the oil via the head gasket, also check the coolant for the same signs of a white substance this indicates head gasket failure and the only solution would be to have the engine re-built to replace the cylinder head gasket.
this is a big job to do

let me know how you get on or if you need further assistance ok

What's the difference between a blown head gasket and a blown intake gasket?

The head gasket goes between the block and the head, and seals the combustion process, and cooling water, and (if oil is pumped obove the heads to valve components) oil pressure.

Intake gaskets seal between the intake manifold and the head, and seal against intake vacuum, and in many cases, coolant.

A badly blown head gasket will so destroy compression in the cylinder that you can hear uneven cranking as that cylinder comes up on compression, kind of a “whir, whir, WHIR, whir, whir, WHIR, whir” with the capitalized whir being the engine spinning much faster due to no compression holding the starter back.

You will never be able to hear a problem with an intake manifold gasket until the engine actually starts to fire and/or run.
