    I have a T5 130 with water in the oil and coolant loss from the header tank. It has only covered 37000 miles in 3 years a 55 plate. Is this a manufacturing defect? is it the block, the head gasket or the cylinder head? This vehicle is a family car and has had no abuse. The problem has occured over night exactly two months out of warranty.

    Any suggestions? The coolant appears to go downn when parked rather than when driving. It is so recent a problem that I have not been able to carry out many diagnostics except look for leaks and inspect the oil filler pipe and dipstick, both of which show emulsion.

I have had exactly the same thing happen to me. In the end it was a faulty water pump which was allowing water into the engine.

We have just had a Tdi through our shop, slowly using water, no leaks external to the engine.
Very slight trace of water at oil filler cap, shining a torch down the filler neck shows oil startng to change colour with water, a lot of vapour coming out of neck when hot.
Conversation with another VW mechanic says, water pump leaks water in oil when faulty, oil cooler leaks oil into water when faulty.
Hope this helps.

I have a 2006 T5 130 PS, bought new, never thrashed. At 140k miles got low water level light on then noticed water in oil (not oil in water). Turned out to be WATER PUMP which (unusually) is housed within the crank case. The bearing was shot to pieces thus allowing water into sump. I saw the old pump and there was 5mm lateral play in bearing - it was bad. But no noises when running. Go to your water pump FIRST, oh - and you need a special puller (borrowed from VW agent) to get old one off. BTW. I just got it back from 200k service today and VW charge £12.95 / ltr for the oil plus VAT. and it took 8.3 ltrs = £126 just for the oil. BUT make sure you use proper stuff 'LONG LIFE III' with spec of 507 00. Its made from gold and diamonds crushed up together (well it must be). DON'T use anything else. I had camshaft and followers replaced at 150k miles because my previous mechanic used lower spec oil. Cost me a grand.

Emissionwiz your wrong and dont give people false info as its a common vw problem on the transporters that oil mixing with the water is 99% the square box on the bottom of engine where the oil filter fits onto it gets blocked brakes lets oil fill into the water so dont give information on what you know as it sounds like your thinking this is a car its not and if you were talking about a car i would say the same , but unless you know about vw transporters then say nothing , ive had 5 with all the same problem , i buy them because people think its the head gone yet i get them flush the system buy a new box and oil filter , problem solved , another thing the box eventualy lets that much oil into the water it blocks everything up and your heaters go cold , so fix the box that the oil filter joins onto flush your system , new oil , and your off on you travels again , but watch for mechanics saying its the head gasket tell them about this common fault , ive forgot what you call the sqaure box thing , becasue most mechanics will say its the head then replace the box for £40 and charge you £350 so do the cheap little things 1st before going for the head gasket change but if it is the head its only £320 to fix up newcastle from a reputable garage yet vw charge you an arm and a leg so dont just think your head gasket has gone its very rare they go on the t4 upwards. hope this helps if i remember the correct name for the box thing i will update you all.

    VW NUT explains it best, thats what i am on about , water pump leaks water in oil when faulty, oil cooler leaks oil into water when faulty and the box that ive mentioned in solution 6 can all make your water tank filler look creamy and oily.



    And solution 5 should be removed for giving people false and depression information.

  • rich1981 Apr 06, 2010

    UPDATE FROM RICH1981 the box is called the oil cooler . REPLACE IT AND I BET YOUR OIL IN WATER WILL STOP.

  • nobby landy Sep 23, 2010

    this was the same as ours - oil in the water (not vice verrsa). You can test the cooler if you have a compressor once it is off the van by putting it on the floor, holes up. Fill the 'water' side to the top with a hose. Then bung up one of the 'oil holes with your thumb and pressuring the other 'oil' hole with a blow-gun - if you get bubbles through the water side it's shot and that's your problem

  • rich1981 Nov 10, 2010

    your post should be deleted for false and depression information. always check the oil cooler and water pump first.

I had the same problem, it was a faulty water pump and oil cooler. Replaced both and all is OK.

Dont listen to people who say its a head problem as they never go on a T5

If there is water in the oil you have either a blown head gasket or a cracked block or cylinder head.

I had the same problem with my T5 130. My mechanic replaced the head gasket to no avail,then we checked the oil filter,that was ok.then we went on to a web forum and found out that the AXD engine suffers from water pump failure.We took it off and it was corroded,the seal had failed and was pumping water into the block.My advice,CHECK WATER PUMP FIRST! Good luck Marc,Somerset.

How do I fix oil being in my radiator but no water in the oil? Oil is not milky or anything on the stick just looks like oil in radiator.


Replace the thermostat. Empty all of the water out, flush with water and a good squirt of dish liquid and run until hot. Drain again and refill with plain water. Empty that and fill with water and anti-freeze.

The air conditioning is completely separate, a standalone system run from a belt on the crankshaft pulley.

Sounds to me that someone has put oil into your water instead of the engine.

My problem is toyota 2lt engine oil in water the oil is clean


Check the engine's oil dipstick. Brown, bubbly oil or any inconsistencies or traces of water on the dipstick can be symptoms of a severe head gasket failure. Have the car's engine checked right away. god bless!

Water get into oil


Water in oil makes the oil go grey / milky or white . Check the cooling system by a pressure test and if it is holding then it will not be water in the oil.. If you are referring to transmission oil then the tan colour indicates burnt oil, and must be replaced. Water in that oil will also be a white cherry/ milky colour.

Refrase 1996 hyundai excel ,oil in water no water in sump oil.


Oil in the water is usually a sign of a head gasket leak, because the high pressure oil passes through to the head in order to lubricate the camshaft.
The oil return passages also go through the head gasket, but are too low pressure to usually cause any problem.
As long as there is no water in the oil or loss of water, I would keep driving it.
The oil in the water will not hurt anything. If it eventually gets worse and leaks water, then you will have to do the head gasket. Costs about $500.
Of you can do it yourself for about $75 if you know how to use a torque wrench.

Hi my toyota corrolla verso radhaeters anti freeze water turns to cream at the top


I'd check the oil and see if you have any "cream" or discoloration of the oil as well.
Sounds like you may have oil mixing into the water...(usually looks like a chocolate milkshake.)
If this is the case, you may have a warped head (from getting too hot) or there might be an area where the water & oil jets are close and merely separated by a gasket. (i.e. Ford's 4.6 oil filter & upper water hose housing.)

Oil in water or water in oil either way isn't too good.

If after checking oil and its not "creamy" as well...maybe a good radiator flush would help.

Hope this helps...

I have oil in my water resivior and its overflowing with oil.


Sounds like you have a leak that may be due to a bad seal,a bad gasket or a cracked head. When the engine is running. Oil pressure is higher than water pressure. But when the engine is shut off oil pressure goes to zero but water pressure is still at 15 psi. untill the engine cools off. that's when you get water and oil to mix. If you do an oil change you could find water in the oil pan. Doing a water pressure test will verify a leak but won't tell you where.

1993 camaro V6 3.4 lt water and oil mixing could it be water pump


Yes there is another way, someone can be messing with your head and pouring water in your oil cap. Do have water in your oil or oil in your water or both? A product called sea foam does a miraculous job at getting water out of oil. As far as keeping it from happening further, the cheap way of course is "bar's stop leak" but man can this stuff do a number on clogging your heater core, even if they say it doesn't, it can happen.

Nissan Sentra GA14 engine - Water in Engine Oil


If the engine has been flushed well including the radiator and you are still getting water in the oil. The culprit is the cylinder head or the block has a crack internally allowing water into the oil.

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 .
