mudduck Posted March 1, 2009 Share Posted March 1, 2009 So I started to notice a milkshake like funk on my oil cap a couple months back. In my expierience, thats not good. I have looked at all the obvious thinks, no oil in the coolant, no coolant loss at all. None. Also have changed out the pcv and the hoses. They also had the milkshake in them and the hoses were shot. I had electrical tape wraped where they had cracked. Anyway, I was adding a little oil the other day and pulled the pcv hoses just to take a look, and water ran out. Not milkshake looking water, but clean clear water. What the hell? Any ideas? This is in a EA82 with 280,000 miles. Link to comment Share on other sites More sharing options...
Frank B Posted March 1, 2009 Share Posted March 1, 2009 Usually you get the moisture in the cap when the engine isn't getting hot enough, for long enough to boil out the moisture from the oil. Or it's time to change the oil. How long of a trip does the car make every day? Is the engine getting up to temp(thermostat working?) The engine needs to get above 180 degrees for at least 30 minutes as a general rule. The moistur ein the air and the condensation that develops as the engine cools is where that comes from. Unless you have an internal coolant leak, which you do not. When you cleaned/replaced the PCV hoses, did you remove the valve covers and clean them up too? The crust develops in there to blockinf flow. Also, is there a high vacuum at the pcv? Remove it and start the engine, or start the engine and remove it and see how well it sucks. Maybe replace the pcv with an OEM one, they say they're better. Link to comment Share on other sites More sharing options...
dhise Posted March 1, 2009 Share Posted March 1, 2009 It's normal in the winter time for me. That oil filler neck sticks way out and doesn't get near as hot as the engine so water condenses there with oil vapor. I just clean it off periodically. The cap stays clean as soon as the weather warms up. My pcv system does stay pretty clean however. Link to comment Share on other sites More sharing options...

The cap stays clean as soon as the weather warms up. My pcv system does stay pretty clean however. Thats what I was thinking, that the oil filler sticks up away from the engine, causing condensation. But, this is the first winter I have ever seen this happen. My other thought is that moisture might have gotten drawn in from a cracked pcv hose. I'm really not worried about it to much. The engine runs good and seems to have plenty of power, for a ea82. I'll keep an eye on things and see what happens as the weather starts to warm up.
