I have an oil leak on the passenger side of the engine, just started, noticed some smoke, I know this just started. Any ideas or thoughts? Thanks Chuck

Cant really see anything from your picture, but if its smoking oil is getting on the manifold prob. Would suspect valve cover gasket

I'd guess its actually coolant leaking. Directly above what looks like the wet spot (presuming thats what you're talking about), is the plastic "T" connector on the heater hose which is prone to failing on these engines.

The dorman replacement part is usually considered the best option. https://amzn.to/2vPG5O5

You sure it's nice a minor coolant leak?? From the t hose above the leak

I think coolant leak as well, looks like the plug well is wet

I agree, coolant leak at the t fitting

T fitting. Doorman sells just the T cheap. Not too hard to swap the whole thing.

Here's how I fixed the leaking T-connector.
