I have oil over all the plus on my optispark. I figured the intake manifold was leaking because i smell burning oil, but it looks like i have some oil at the front of the engine as well. Where do you think this might be coming from?

the waterpump has a small coupling that drives it that runs throught the front timing cover. the seal for the waterpump drive on the cover could be bad? won't really know till you clean it off and recheck it. it could still be the intake also.

Intake mani will leak down front and back of engine ..find highest point on engine wet with oil and find your leak

I replaced the waterpump recently, but it really seems like it's coming from the intake manifold. I guess I will double check.

Your problem will be the water pump shaft seal in the timing cover. They take care to install and are easily damaged. Your recent replacement of the pump is a dead giveaway. Do a search on how to install/replace them on the car. When they are damaged oil gets everywhere.

Oh man..

So I will need new water pump gaskets as well? Is this seal easy to get? I guess I could just go to GM?
