I just noticed some smoke from under the hood and took a look. It appears there is slight coolant leak near the rearmost exhaust manifold. Im thinking I have a failed head gasket. Could it be something else? How much does replacing the head gasket cost?

Thanks in advance.

It could be a heater hose.

Typically when the head gasket goes you get coolant in one or more cylinders and not an external leak.

hmm - that would be a relief. I will have to look much more closely. It was wet over the rearmost exhaust but maybe I missed a hose or something back there. I'll keep my fingers crossed.

k - I looked again and another possibilty is the rear camshaft seal. I assumed it was coolant leaking but it might be oil. So how hard is to change a rear chamshaft seal?

Pretty unusual for an hg to go on the outside I think. Track it down.

So is it as easy as just removing the rear cam tower cover via the 4 bolts and replacing the gasket? Anything I need to worry about?

Um, i think it is only 3 bolts, and no nothing to worry about. The hippo gasket is about 10 bucks i think. Make sure it isn't coolant from the those lines, as coolant dripping on the bellhousing = new clutch needed.
