Hi all, it's been a while  My Car currently has water in the oil and is leaking this lovely mixture from what appears to be the front of the engine, I am thinking this maybe the oil cooler but other oil cooler failures on here seem to suggest oil in the water is the sign of failure.........Which I don't have !......... Any advice welcome ! Thanks

Might help us if you indicate what engine you have? 

Water in the oil = head gasket

Oil in the water = Oil Cooler.

Oil Cooler issues only affect V6

Sorry Tunnie.! 2000 2.5

Assume you do keep a healthy mixture of anti-freeze to water of 50/50 in the system?

How much coolant are you loosing?

I'd say its worth inspecting the water pump seal first, as you say there is water in the oil, but its coming from the front of the engine? 

The dipstick for oil, does that contain water?

Yup changed thermostat last year and refilled with 50/50 couple of minor top ups with just water since.
Had sudden over heating last friday ok when moving but straight to max when stationary, got home and topped up with 3 litres approx of water, checked oil then and some gunk in filler cap (usaual with my short commute to work) but dipstick looked fine. what i thought was an oil leak developed over the weekend have now noticed the puddles contain oil and water, checked dipstick an this has a slight creamy'ness to it and the gunk in filler cap is almost white !

Right, well I don't think thats HG (2.5's are practically bullet proof for them)

You are loosing coolant somewhere, 3 litres is a lot of fluids. If HG was pishing that out, you would have zero compression.

Check the HBV for any leaks, as its common although at the back of the engine. Also check the water pump, to me it sounds like a coolant leak, but mixing with small amounts of oil.

Assuming when you lost 3 litres of coolant, your oil loss was minimal?

[OmegaGav]

Yep thought it was rare for HG to go  No obvious leaks from HBV that was changed about 4 years ago. there was no oil leaking before water loss, now I'm not sure how quickly the water was lost as I done a full service (Oil, filters & plugs) about 5 weeks ago then we went on a holiday to wales (5 x people 1 x dog and way too much luggage (women  ) drove like a dream and covered about 700 miles all fine before we left and hadn't checked since being back but hadn't noticed any over heating but there again most of my trips are fairly short so may not have reached full temp before stopping ! Water pump was replaced 3 & 1/2 years ago along with the cambelt

When you say you have water in the oil are you seeing this from the dipstick? The oil filler cap? Or somewhere else?
If your oil cooler is failing or has failed, there will be oil in your water/coolant reservoir which can look like brownish mayonnaise..... if this is the case then your water system will have oil in it, in which case the radiator will not be cooling properly which could cause over heating.
Need some more information or some photos mate to help any more.

Water not leaking out the rear side cly head HG...

[OmegaGav]

Just checked again and dipstick seems fine (Engine cold) last time I checked it was hot and felt oil looked lighter but thinking I only changed the oil 5 weeks ago.......... water seems normal but there is no puddle of water on the floor only a puddle of oil 

[RobseyMV6]

Is it lumpy on start up in morning, any white smoke from rear pipe?

[OmegaGav]

Hi Rob ! Some times it will take 2 short trys to start but always fires on second go sometimes I think it sounds like a slight blowing exhaust when cold but when hot the engine is sweet quiet as a mouse ! Now I have the conundrum of losing water and a puddle of oil under the car 

[OmegaGav]

Daz, i take it we still have to use photobucket to upload photos ??

[RobseyMV6]

Hi Gav, need to look under on rumps really...

[OmegaGav]

Sirloin or fillet ?
