Ok today I went out and checked my airbox to see how my K&N filter was working and I found alot of Oil in the Y-pipe and the coragated tubing. I am not extremly worried, but just want to make sure its normal to have oil in there.

Then I checked my stock TBB because I have been hearing a blow-off noise when I let off. I found quite a lot of oil on the under side of the TBB.It was mostly on around the back of it near the Throttle Body. Do you think its torn? TIA. I planned on replacing it soon, but it seems like its time!
