Re: Longevity of motor with a leaky head gasket?

If you have a milky appearance under the oil cap, then you have coolant in the oil. If you have coolant in the oil, the bearings are all short-timers.

You'll spin a bearing long before the engine fails due to the head gasket.

As Maxwedge states, I'd put more stock into the lower intake gaskets, as these are a sore point for this engine (3.4) and this is what they do when they fail.
