I have been hunting for oil leaks. So far I have:
- replaced valve cover gaskets
- chain cover gaskets
- oil bridge gaskets
- breather and oil pressure sensor gaskets

Oil lines appear dry. Where should I look next?

Oil return tube O-rings, case through-bolt O-rings, cylinder base O-rings, all tend to leak over time as they shrink, harden, and crack from heat. We replace these with Viton ones which last far longer than OEM.

This is probably answered elsewhere but how much can you do with the engine in the car? I just realized the the power steering pump shaft main seal is leaking too. That one I can handle with the engine in the car.

Everything I mentioned are engine-out procedures and the engine needs to be partially disassembled.

These are things normally done when the car needs a valve job.
