Hi all, I have a 2000 Chevy Impala with the 3.4L V6 engine in it. I was checking the coolant level in it today and noticed what looked like oil droplets mixed in with the coolant. There was a thick sludge around the radiatior cap too.
Now, i've heard that these engines were notorious for leaking coolant into the oil via a bad intake gasket. But can it to the opposite? There is no coolant in the oil that I can see.
Could this be a bad intake gasket? Most info I've seen said that the plastic intake manifolds were to blame for the leaky gaskets... but the manifold on my Impala is alluminum.
We've had this car for about 8 months now. It has 82,000 miles on it with no problems so far. I also noticed that it has GREEN coolant in it... I thought '96 and newer vehicles used the DexCool?
