Just out of curiosity does anyone else have a slight residue of oil in the coolant overflow?
Would this indicate a problem of some type?

 

uh oh, are you sure its engine oil?

 

Looks & smells like engine oil-It is a VERY minor amount-
Thought I blew a head gasket yesterday, but turned out it was only the throttle body tube coming loose-Led me to look at EVERYTHING w/ a fine tooth comb & noticed this

 

Let the engine cool off, pull off the radiator cap and see if there is a oil film floating ontop. and/or check your oil and see if its a dark brown color.

 

Already checked that all out-Immediately pulled the dipstick-fine, No oil in the radiator-Car run's great, just wondering

 

I don't know man, I wouldn't worry about it.

 

That could be scary! Umm my car had oil residue in it but DIDNT smell like oil. I had 45,XXX miles on the car.

 

Did you put Redline's Water wetter in your radiator? If so that usually causes a sludge looking type of stuff to show up in your overflow.

 

I once thought i saw oil in my overflow, but after further inspection it turned out to just be dirt and sludge. I think what happens is, dirt is basicly sucked up by the over flow tube under pressure changes.
