Default Major oil leak

Ok so my friend had headers installed and now it leaks oil. It pours out the drivers side right under and behind the 5 cylinder. What is supposed to be there we tried to get pics but the headers are in the way

There's nothing back there. Temp sensor to the left of that area, but coolant would leak from that.

Check the valve cover, back of the intake and rear main.

the weird thing was it was fine for 2 weeks after the headers install then bam one day it started pouring out the side. There is some object hanging by cable that they couldn't figure out where it goes so I think that has something to do w/ it. BTW this is for a friend not my car

Is there an aftermarket oil pressure gauge in the mix?

since he has a 94 the oil pressure sending unit should be in front of the filter i think. Would he need to remove his longtubes to get to either the sending unit or low oil sensor?

lol it still runs besides the fact that oil spews out the side. I told him if it's coming exactly where he's saying its coming from that he is either wrong or something blew a hole in his block lol
