Hey,

i was look at my car today and i was checking every thing out the fluids on the car and what not. then i took my oil cap off and there was 1/8 to 1/4 inch of white/tan gooey substance under it and in the oil valley. I know people that have Vw`s and have the same problem they say it is due to condonsation in the engin and due to short tips. But i has also heard that is a falt in the head gasket. If any one Has any input on this please let me know


- Thank you

I was thinking the same thing (oil and water mix) Sounds like it may be a head gasket.

This is ancient history, but when I bought a '78 Monaco in 1986 it had the white under the cap too. I didn't even notice it until after I did my first oil change and then it took maybe one more oil change and it never came back after that! So hopefully it's just some condensation because I drove that Monaco for another two years with no notice of problems or the gooey stuff coming back.

Also, that car sat outside for quite awhile before I bought it, so I don't know if that's a factor.

I would change your oil and see if the milky substance comes back. Also, keep an eye on your coolant resevoir for the milky substance. The Catera has a history of bad oil coolers, which unfortunately is not a cheap fix. If the oil cooler does fail, you could get either oil in your coolant, or coolant in your oil. I believe that you would probably get oil in your coolant because the oil pressure should be higher than the coolant pressure. You may just have a little condensation in your oil and be fine, just be aware of both the oil and coolant (if you have a bad oil cooler, the sooner you get it fixed the better).

Well, this stuff on mine turned out to be due to cold weather here in MN. It warmed up around 50 to 55 and no white sh** at all.

Hey thanks for all the help. I dont think it is the oil leaking or the coolent leaking i think it is due to cold weather. As the car has just sat in my driveway since december And in New Jersey it is pretty cold and has snowed like 5-6 times to date

I had the same problem with my 2000 Catera - the milky white oil sludge in filler tube and I live in NJ and it has been below 30 here for some time. The dealer said it's a common problem but they did a pressure test anyway and they said it was the oil cooler, which I spent $1,000 to have fixed. What a pain!
