Ok so the car is still leaking/smoking from the same area.. I am thinking maybe the stock oil pressure sensor or a galley plug is leaking oil onto the top of the block, and it's dripping down the back of the motor near the up pipe as well as leaking down into my timing cover and onto the header crosspipe.

Either that or it's leaking from the top of the block AND somewhere inside the timing cover.

I saw some oil drip off my oil filter so I'm going to pick up a new oil cooler gasket and replace that when I change my oil this weekend, it's due. I had the oil cooler leak fixed by a shop about a year ago, but who knows what they did to remedy it...

I wonder if there's a diagram of where all the oil galley plugs in the block are?

The castings in this image don't quite match up with my photos, but I'm sure it's pretty close. Can anyone verify?



The two open holes with two bolt holes on either side are for the cooling system, correct?

Ok so tonight I took my alternator off for the first time and saw quite a bit of fresh oil around the stock oil pressure sensor, I start the car up and can see oil seeping through between the brass and plastic parts.

Super happy I found this and hopefully it is the leak I have been chasing all this time. Trying to plug the hole, I can't find any tapered plugs around my shop that matches the threads of either the galley plug or the sensor threads. My dad is a pipefitter so we have quite a few tapered pipe fittings laying around.. Does anyone know the size of either of these threads?

I ended up just buying a new oil pressure switch today for $9, we couldn't find any plugs at the auto store that fit either size of thread. The new switch does not leak, so I'm about to degrease my engine again and go for a drive.

So far, so good.. Pop off your alternator and look at the oil pressure switch with the motor running, see if it's leaking. The parts guy at the auto store told me it's pretty common for them to leak. Taking the alternator off takes under 10 minutes, it's easy.
