OK, i did do a search and pulled a bit of info, but I did not want to resurrect any old posts. Most of those led to cracked cylinders or head gaskets. <p>About 4 months ago I got a low coolant light, it did go away when the car warmed up. I called the service department and was told to add a little water. <br>I took the car in about 2 months ago for an oil change and re-told them about the low coolant light, the service adviser did not seem surprised and said they would top it off if needed. <br>Well today I get the light again. It turned off after 10 sec, so I drove the car home. When I checked the coolant level was near the low mark. I also noticed what looks like white deposit inside the reservoir tank, and the coolant looks kind of yellow. I check my engine oil noticed that it is way above the X-mark line. <br>My car has been running great and my temp needle sticks straight to the middle. <br>The engine oil looked fine, not cloudy or bubbly, and I have no leaks under the car. <p>Should I be worried? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Unfortunately, yes....very much so. Sounds like a head gasket <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Re: (phuz)

That really sucks. If the head gasket goes, would oil get into the coolant line and mix? Also, what could be causing the white debris in the coolant tank. It seems to be stuck to the sides of the plastic. When I scrape it off it just dissolves.<p>With a head gasket would I see any leaks on the outside? or it could be fine on the outside but leaking on the inside.

I tried the compression test and there was no build up when I tried to release the cap. I added some extra coolant to get about the fill line before I posted this, and before I did the compression test, I noticed that there is definitely some kind of contamination in there. <br>Could the coolant system get contaminated without a leak somewhere?<BR><BR>

Doesn't sound like a head gasket to me, with no evidence of oil/water mixing.<p>edit: Our head gasket is pretty heavy duty.<BR><BR>

Re: (SHIFT_S60R)

I might have to agree. Since the oil looks perfect, they may have just overfilled it when I got the service done. The contamination could just be pointing to an Coolant flush. Since I didn't build up any pressure on Matt's suggestion, I think I'll just make an appointment to get the flush and pressure check done, and CROSS MY FINGERS...

Are you sure you don't have a radiator leak? (very common problem)<p>If you suspect the head gasket, you could test the coolant for hydrocarbons... i think they sell test kits in NAPA.

theres no place in the rad for the oil and coolant to mix ...... <p>as I say that .... <p>they stayed with the rear set up attached to the oil pan correct ? <br>I know up to 04 they did but did they do it in the Rs ? <BR><BR>

Re: (SHIFT_S60R)

So the oil would look normal? Then what would be causing the added volume to the oil?

After reading Chilled Man's edit, I went and looked at VADIS, and it does look like there would be contamination if the head gasket was the culprit.<p>edit: Water/oil do not always mix, but that is a symptom of a blown head gasket.

If you do get some sort of a test kit...<p>If its multi-use.<p>I'd be happy to chip in.

chinaonnitrous, I was actually thinking of you during this thread. Can you feel the love?<p>Are you checking the oil with the engine cool?

If your oil level dramatically increased and you didn't add fluid, it had to come from somewhere...and unfortunately that really does sound like a head gasket problem.<p>How did you determine that the oil was clean? If coolant did get in the mix, it would settle beneath the oil since it is more dense. Because of that, the oil might appear clean on the dipstick.

So back to the original question...the extra oil level is coming from where?
