Pesky oil leak possibly determined to be from a weird place. need help diagnosing/fix

[stallionmike]

Hey everyone, this is my first post here and i need some help with an oil leak. so just a little background; just recently i did some brake work, replaced master cylinder, front rotors and pads. at same time i did oil change cuz i was WELL overdue, had to be at least around 10K and over(i know, terrible). next day i have my car on the road again and feeling great cuz i havent driven it in over a month with the not having brakes, and waiting for the piece. the day after that i notice that it's starting to rain under the car! my dad and i deduced that, first, it only leaks when the car is on and we think it's coming from the cooling hose flange at the end of the cylinder head, on the right side. it's not leaking from the piece itself but from where it makes makes contact with the head. from there it flows down and over the tranny, around to the lowest point and drops. it's somewhat of a fast leak. i filled the engine with Mobil super 2000 high mileage oil 10w-30, and topped it off a couple times with 10w-40 motomaster junk lying around. i'm not sure what oil i had in it before, and the piece itself, the flange, i believe was replaced about a year ago when it was leaking coolant. though now it seams to be leaking oil which makes no sense to me.
any help in telling me what exactly is leaking, why, and how to fix it is greatly appreciated!

if you're getting oil from that flange than you have bigger issues than a leak. check to make sure it's not coming from the valve cover.

it's all good, turns out it was the oil pressure switch just to the left of the flange. i couldnt really see it leaking cuz of the rubber boot so the first place i saw it show up was on the flange. i changed the sensor and oil leak is gone. thanks for your input, really glad it turned out to be something small and easy to fix
