I've got oil coming up through 2 intake bolts

Yes on 592. Remove bolt, one at a time. Clean and use thread sealer on bolts
Retorque as per service manual

Thank you, just got to wait for the car to cool off a bit first.
Is that an oil passage that the bolt is threaded into? A blind hole into the crank case? Is oil leaking (being forced up) past the bolt shoulder and through a gap between the shoulder and the opposing surface of the manifold bolt-hole? Or is oil leaking from the valve cover gasket and just accumulating there near the bolt?
Its coming up from the bolt hole, it only pools in the bolt valley, and I've never seen any oil on the side of the head, just the intake.
I also re-torqued all the intake bolts a couple weeks ago when I first noticed it.

maybe you could put a flat washer under the bolt and see what happens.
I read that copper washers have been recommended for this sort of thing.

Oil leak at intake manifold bolt
I have a leak at the rear manifold bolt on the passenger side, all the other bolt heads are dry. Does that bolt go thru an oil passage and need some special compound ? The manifold is an aluminum Edelbrock DP4B. See the photo. Advice on how to proceed ? Last of my leaks on a 5,000 mile motor...

If there's a reason why using a copper washer in this application is not recommended I'd like to hear it. Or go ahead and be silent and downvote this post too.

I didn't down vote, but I had lt592 on hand and did not have copper washer on had.
