Oil in Coolant

[mjdemaris]

I have a 2000 montana, 3.4L. Since I purchased this vehicle, it has had oil in the coolant. The head gasket has been replaced twice and i think the intake manifold gasket.

I've flushed the coolant several times.

Still, I have oil in the coolant.

Any ideas where this is coming from?

Was the head gasket done because it actually failed or just because oil in coolant?
If you have the combo rad/tranny cooler, suspect the rad has failed internally and allowed tranny fluid to mix. If that's the case, you can damage your tranny if you continue to drive it. Check your tranny fluid and see if it has coolant in it.

Survey sez: The #1 answer is intake manifold gaskets. Or could be a cracked head.
