Oil in intake tube/throttle body?! WTF?!

[07sierraclassic]

So my truck has been running a little rough lately and has a CEL showing, so I went up and got the codes from vato zone. I have a p0307, p0175, p0101 and p0172. I replace plug wires as one had tubbed against the steering shaft and worn through the insulation. Today I decided to check all my connections on my intake to make sure that nothing was loose. What i found instead was a small puddle of oil in the throttle body?! Can anyone shed some light on this?!

Truck is an '07 sierra classic with L59 5.3, stock with AFE intake and blowmaster muffler

I'm a expert with this shit since my trucks engine and shit was a lemon lol jk . Like said above the one thing it is pcv valve and also check the intake manifold gasket they replaced all that on mine . But after more and more problems they put a new motor in the truck . They also had problems with the intake gasket had a shit ton of papers take it in it was almost like a recall on the gasket but they never sent one out .
