Water in oil. Arrg.

[Thebughunter]

Bought a 992.0 with unknown history, excellent interior and body. I looked at the dipstick before purchase, but not under the oil fill cap (I usually do, but it was howling cold and I was so impressed with the rest of the car that I let my guard down). After replacing the timing belt and WP, I go to add oil and see moisture under the cap, a little milky looking, classic water in oil evidence. Drove it 50 miles or so, and fresh moisture each time I check. Usually I say in these cases, dream of bad head gasket, but it's probably a bad head (crack or warp). I assume that this is also true for the 2.0, or is there a small, cheap part that always breaks that causes this, and is replaceable in minutes on beetles? I also believe in the tooth fairy about as much...

it's not the head gasket.

in fact, this is very common when the seals of the filler neck and the pcv hose fail.

not really much to worry about, parts are cheap, labor is easy.

This is very common with the 2.0--don't worry about it.

It's about the crappiest looking mess you'll ever see in an engine but it's no big deal apparently. I was like you--I about filled my drawers when I saw it the first time.

You should check and/or clean the "PCV" connection and hose every time you change your oil. However the "PCV" hose connection at the upper air intake is a "heater"; it is supposed to take care of that moister for you, but cannot if it is clogged.

This stuff will coat the inside of the valve cover it you let it go to long.

you can also grab two new rubber seals from the dealer, one for the base of the neck and one for under the cap. The new ones are a little thicker and will help keep moisture out which in turn helps it from collecting under the cap on short drives.

Thanks, you have given me new hope. The seals at the top and bottom of the cap body seem decent, but I don't know how sensitive they are. However, the funky hose to the intake air looks to have a split at a junction, I don't think that I did it when I pulled it off, it looks older, not like a fresh tear. Not sure if that would do it or not. The hose had some mayo in it, but not too bad, not plugged.
Thanks, I'll see what happens with a new hose, maybe new seals too.

I would replace the gaskets(very cheap) and clean the hoses on the inside and PCV (under oil fill cap ). Use fully synthetic oil as that would combat most of the moisture as well. These engines are known for that type of moisture problem ??? Also short trips in moist conditions will also contribute to this... GL....KP..

When you take your oil filler cap and cap body off the valve cover, run your finger around the inside of the vale cover and see if any "mayo" is on it.

Yep totally normal, both our 2.0's do it, one is a 2000 with 66k on it and the other a 2007 with 18k on it (im from the UK we still have the 2.0 brand new over here!).

Our '07 has a different rocker cover than the '00 (the spout bit thats removeable on the '00 is part of the metal rocker cover on the '07) but it still gets the yellow gunk the same, I just clean it out every so often
