Strange yellow color underneath


Recommended Posts

Hello,

I have a strange yellow color underneath my car, just under the oil pan. It looks like cooked oil.

I don't know if it's a normal thing to have on a car or not. My car is new, has no apparent oil leaks; I have never needed to add some oil and I have about 2000 miles on my car.

Maybe this picture would be helpful; you see, all the surface on the picture is yellow and the texture is solid, never been liquid. Should I be worried or is it something normal after the break-in procedure?

Thank you for your comments.post-3260-1110392571.gif

Yes Loren, it looks like a bit the picture you gently posted. I thought it was some oil leak which cooked while I was driving...The coating is not homogeneously spread, it's a bit irregular but roughly covers all the surface of the oil pan. Thank you again for your precious help Loren, you are so devoted to the members of the forum, I admire your dedication.

This is a protective coating put on the underside of the car by the factory. Doesn't hurt anything - you can take it all off (a lot of work) or leave it as is.

Your underneath should look like this:

The cosomline will attract dirt, which will make your car heavier, and thus slower.

:eek:

Wow, Orient express your car looks also very impressive underneath!! I see you like things to be very neat. That may be the resason why you and your car won many beauty contests.

:thumbup:

Also, could you please tell me if it is really safe for the underneath of the car to get along without this extra coating please? I mean, don't you fear rust or aggression from salted air, water...when you drive your Carrera?

I live next to the sea shore so, I wonder if it would cause any particular harm. I would really like to get rid of this ugly coating underneath.

Thanks.

If you live in an area where the roads are salted, or by the sea shore where salt fog and high humidity is a problem, then you may want to consider leaving it on. Areas that have heavy salt fog and high humidity are really tough on aluminum alloy materials like engine and transmissions.

I am lucky that even though I am 20 miles from the ocean, I do not have problems with corrosion.

Orient Express, thanks for your kinf response. You know, I probably made a mistake; well I took off all the coating under the oil pan. Now considering your advice, I'm wondering where I could find a compatible protectant on the market...I'm sometimes so impatient... :D

You will be fine, don't worry about it. If you live in europe, then take your car to Stuttgart to the Porsche dealer over by the factory, and for 60 euros they will spray on a fresh coating.

If you don't want to do that, just hit the underside of the car with a pressure washer every once and a while and that will wash off the grime and dirt accumulations.
