Thanks for the suggestions.

It's not the rear cam seals, I replaced both 3 months ago and they are not leaking. I've learned how to look them over with a mirror and can wiggle my fingers over the one on the right- no leak.

Had the Monty in a shop to have the spark plugs replaced (I wimped out on pulling the intake manifold to do it...) and they think its the front main seal. Their contention is that the oil is blown by the fan to the right side and collects on the side of the engine near the exhaust manifold and the alternator, then drips down. It could be-- the previous owner had the timing belt replaced at 67k but didn't have the mail seal replaced as part of the job. SHAME! <img src="/forums/images/graemlins/shame.gif" alt="" />

I'm not sure this is the explanation. I'm running it with the skid pan off and just don't see any sign of oil dripping around the crankshaft bearing. However, they are correct in that oil drips off the alternator and the center exhaust manifold bolts.

Could it be the front cam seals? How can I tell?

So, its still a puzzle.... <img src="/forums/images/graemlins/confused.gif" alt="" />
