Air intake

[SCOTT L]

I was cleaning my MAF sensor (cel was on) and I noticed that there was oil in the air intake tube. I removed the air intake from the throttle body and the throttle body had a slug build up on the side between the manifold and the throttle body. Then I removed the throttle body from the manifold and the slug seem to get worse. I wipe out all the slug that I could reach. Does this sound normale? As far as I know everything is stock.

That sounds normal, a good tb cleaning now and then will keep it down. That sludge is a mix of oil from the crankcase vent and dirt particles mixed together. Air intake cleaner will eat that stuff right up.
