I have an 03 CTS with the 3.2L motor. While it was at the shop today getting the rearend oil changed (differential whine), I noticed oil on the underside near the front of the engine. Investigating further I popped the hood and found oil all over the intake tubes going down in front of the engine. I pulled off the tubes and found more oil on the inside on both sides, and inside the intake manifold.

Has anyone else experienced this or have any idea what might be causing it? Thanks!

the screws on your heads might be loose and causing this. tighten them up (a few people have done this) and this should solve your problem

I had the same probleme a month ago, tightend the screws and probleme was solved for me.
So what "screws" are you talking about? My car is at the dealership right now for an oil change, replacement of the left rear hub bearing (i thought it was the diff, hence why i was changing the diff fluid last week), and replacement of the evap vent valve (causing CEL and difficulty starting after fueling). They tried to find where the oil in the intake is comming from but said they cant figure it out. When I mentioned tightening the "screws on the heads" they werent sure what I was talking about. Thanks!

haha...this is your cadillac dealership that doesnt know what you mean by tightening the screws on your heads? you better go pick up your car ASAP if they dont know what you mean, cause they obviously only have your car in there to take your money. we are talking about the screws/bolts that hold the heads on...

Is it the heads or the valvecovers? For me it was the screws on the valve covers, they were all loose. It takes a liitle work to get at them, about 30 min each side.

What size torques socket was the valve cover bolts? I don't feel like buying a whole set I have a couple but not the right ones.

you would be better off just buying a whole set, seeing that you need them for damn near everything on the car

8mm normal socket will work, can't remember what that converts to in torx. don't over tighted you'll snap the bolts. throw some lock-tite blue on them if you have them out. to get all the bolts out you'll have to remove your intake manifold.
If your head bolts are loose you'll probably have bigger problems (they would be lock-tighted)
