AUDI A3 2.0FSI 2004 water in oil with no or very little coolant loss

I'm stuggling to find the cause of water/coolant in the oil.. I have white smoke/steam omitting from my exhaust...seems worse due to the fact its a large twin rear pipe...and worse in colder climates. So i started to look for the cause, one being water/coolant mixing with the oil in the engine...i noticed the oil cap/dipstick have small milky deposits on them...not foamy/frothy.. the coolant level has dropped very slightly over 4 weeks, so i don't think its enough to cause the problem.. Am i missing anything obvious? No power loss, No warnings.. Recently has a service and mot (i'm in the uk) Any help would be much appreciated

SOURCE: thick white smoke coming from exhaust

If it looks like a James Bond movie, you have a blown headgasket

SOURCE: Water mixing with engine oil

5.7's had all kinds of problems with intake manifolds but it could also be a head gasket leaking. One way to check is to pull out your spark plugs and have a look at them. One of them will should be really white looking, that is the cylinder where the coolant is leaking into. A good rule of thumb (but not always true) is that if the coolant is leaking into one of the cylinders at the very front or very back of the engine, it is an intake leak. If the coolant is leaking in one of the middle cylinders, it is a head leak.
But the only way to know absolutly for sure is to pull the intake off and look for a break in the gasket, if you see that you know its the intake manifold. If you cant see any signs of leakage its probally a head problem. Another word of advice, there is an updated gasket from fellpro that lasts longer that the OEM gasket.

SOURCE: engine oil mixed in coolant

this would more than likely be cause by a bad cylinder head gasket. I would bet 89% this is your problem.

SOURCE: eating up oil but no visible leak on the driveway or underneath

Oops! Sounds like your engine block is cracked,or your engine heads are warped, or you need new head gaskets. The cheapest problem is the last one. However it still is not cheap. Most head gasket sets cost at least $100 or more. To see if you need head gaskets, after running the car for about 15 minutes, pull out the oil dipstick and see if you see oil or water bubbles on the stick. If you need head gaskets check ebay for your model, that's likely going to be your cheapest source. Also possibly the engine blocked is cracked internally. That explains the loss of oil AND coolant out the pipe. But this also comes with overheating, so if your car is not overheating then this may not be the problem. First advice: BE REAL CAREFUL! CONSTANTLY STOP TO CHECK AND ADD OIL AND COOLANT until you fix the problem. Another advice, take your car to a reputable repair shop and have the engine pressure tested for leaks to find the source. WARNING: Do not use engine block leak sealers, they mess up a lot of stuff on your engine, especially the radiator heater core.

Problem with Cars & Trucks I have a 1996 Buick


what does your temp gauge read i almost bet you have a bad thermostat causing the motor to get overheated at times then come out of the overflow tank , or your radiator fans are not working possibly a fuse/relay or temperature sending unit located near the thermostat housing {that would also make the ac compressor not to come on} could also be a vapor lock basically air in the coolant system[ from not filling up enough or bleeding the system or using a vacuum suction tool } causing the flow of water to be less

Oil in ovverflo of coolant but not the reverse drive everyday flush once month


If there is oil in water, then there may be a head gasket leak. However, half a quart of oil loss every 15,000 mi. is not bad. If van runs perfectly, then I wouldn't worry too much about it. Maybe try some Bar's Leaks Head Gasket Repair for $30 or so to fix the slow leak in the coolant system.

If no external leak and the transmission fluid colour looks white, the problem belongs to the automatic gearbox oil cooler. The oil cooler has broke mixing the gearbox oil and coolant causing this milkshake. It's a small radiator core type oil / water heat exchanger. It is cracked inside and transmission oil is mixed with engine coolant. Because the transmission oil pressure is greater than engine coolant pressure, the transmission fluid level drops. See also the coolant colour inside recovery coolant reservoir inder bonnet! It could be like this:

You're going to need to visually inspect for leaks and if no external leaks are evident I suspect your head gaskets are leaking again - check oil for coolant in oil - it will look milky

The coolant level leaks on my 2004 a4, after i just had the hoses and all these other parts changed about two months ago. Could this have something to do with the the oil? What else can i do i h


Check the coolant temperature sensor housing in back of the engine. This is made out of plastic on some model years A4 and eventually leaks coolant.

Have a small coolant leak dripping onto transaxle


It could be as simple as a leaking hose, but it may also be a corroded alloy hose fitting nipple.

Get is seen to by a mechanic before it fails completely, causing complete loss of coolant and expensive cooked motor.

Audi A4 2.5 V6 TDI - Creamy grey coolant in expansion tank


Sounds like blown head gasket (or worse) still to me.
Remove oil filler cap and look for grey oil.
Never use water these days but special coolant. Water makes vapour spots and cause block cracks, worse then blown gaskets!!!
vapour does not cool very well.
Look like you have cracks already.
Take a compression test if possible. But might not show op at that temperature.
The gauge indication troubles me.
