oil out of cylinder 7 exhaust port bolt holes?

[longblue72]

As what the title says, yesterday I went to put on a set of headers for my truck. I was unbolting the stock manifold on the driver side and got to the furthest bolts closest to the firewall, and they came out black with oil. My engine does not smoke a bit. I ran my finger inside the exhaust port and it was dry. Do any of you guys have a clue on what the problem could be?

I think that problem is causing a minor leak, would teflon be safe to put around the bolt to stop the leak?

Thanks guys

valve cover or rear intake gasket or oil sending unit?

thanks for the quick response!, so you believe it could be on of those three causing it?
if its valve cover would oil just be seeping out?
Intake gasket being bad and done for?
and oil sending unit i have no clue haha

Those bolts go into blind holes. No chance of oil leak from there. If the bolts were wet with oil, the oil has wicked up the threads from some other leak source, like valve covers.

Thank you tx for that info!
