I'm not sure what it could be or what's a common issue. I wanted to maybe know what I'm dealing with back there before I go and take the intake manifold off to have a look. I really can't see much back there except for a lot of oil that leaked out. I will spray degreaser on it when I get home to try and lock in where it's coming from. It's nothing I could have done because I have never been back there yet. It's definitely not the oil pan drain plug, oil filter/oil sending unit area, or the head gasket, or valve cover gasket. No smoke, over heating, or cloudy oil. Is it the oil line going to the turbo perhaps?

 

Do you have any pictures?

 

I don't I can barely see in there myself that's why I think I need to take the IM off

 

Make sure it isn't your oil pressure switch leaking in the back of the engine.

 

Is that located behind the engine under the IM?

 

Did you say it was by the intake manifold? Or did you mean exhaust manifold?

 

It's leaking below the intake manifold

 

I don't think there is anything oil related below the intake up top besides headgasket, How far down below it is it? I could be an oil pan gasket?'

Technically the oil pressure switch is underneath the intake manifold lol, just drivers side is all.

 

Pretty sure he's right. I have a little leak under my intake manifold and it is definitely the Oil pressure switch. Just get the adapter and pull it out, put a little bit of RTV on it and screw it all the way back in.
