Default Intake oil leak?

I have a large oil leak that Seems like its comming from underneath the intake. I took the intake (92 fast) off and the rear of it was pretty wet underneath, but im having a little trouble pinpointing exactly where its comming from. The pass rear intake runner seemed like it has a trail leading from its gasket , but there was also alot of moisture where the knock sensor is. Also the knock sensor i think is supposed to have a black rubber seal around it that seems to be missing. The front has it, but not the rear. This is odd because i have never removed the knock sensor or vally cover from this car. I bought this car brand new in 2000 and am the only person to ever touch it. Do you guys think i need new intake gaskets ir maybe the knock sensor gasket thats missing. Any advise is appreciated. Thanks

If its a large oil leak then Id check the oil pressure sensor first

Ooil pressure sending unit can be pulled out, threads cleaned, and wrapped with Teflon tape and reinserted. I believe the cam sensor next to it has an o ring seal. I'd also throw on new intake seals if they are questionable. I would also look to do a valley cover gasket with the two knock sensor gaskets which should come with it. Top end should be sealed up nicely then.

I recently broke my opsu while searching for the leak, and replaced it. The leak was there before i broke it and after i replaced it. No sign of oil on the old opsu either. R the gaskets for the knock sensor sold separately?

I doubt its the knock sensor, but possible. Check the oil pressure sensor and the valley cover. I have seen a few that had loose valley cover bolts (on a new engine that hadn't been apart) and oil was pouring out.
