Pulled my ST engine cover and found something strange... could use some help

Just got the car yeaterday... love it!! I pulled off the engine cover to look around and noticed something strange. There see to be an open vacuum port on the intake, sucks hard when you give it gas. My concern is it is after the filter!

Any body ssend me a pic of theirs? Here is a pic, circled the port. Also stuck a wire in there to make sure it didn't bottom out.

looks like the crank case breather should attach to there, is there a similar port on the valve cover??? If so i would think a hose should attach the two. But if air is sucking through thats def not right and i wouldnt drive it. You could plug the hole and it will be fine, at least to get it to the dealer. Must be before the MAF, or it would run pretty bad i would think

yeah I agree... I looked every where for a hose etc not connected all around the crankcase but I couldn't find anything. I am going to plug it till I can get to the dealer tomorrow or Saturday

According to the workshop manual, that shouldn't even be there...


I haven't taken my cover off my ST3, so I don't know if mine has it, but I do know that mine doesn't have the metal shields yours has. Maybe the port was something in the original design but then removed?

The ST is speed density tuned and runs off of 3 MAP sensors unlike many cars that base their calculations off of the MAF. And i will go check mine out while at work but right now i gotta run.

Ahh just deciding to cap the port is pretty stupid. You have not one single idea of what it is for, but just block it off anyway. Plain stupid IMO.
When you screw up stuff ,and the warranty is NOT going to cover it.. I'll laugh.
If the thing was a problem, but you did not mess with it.. then actually no problem, you still had a warranty. As is, your are screwing yourself with foolish behavior.
If you actually KNEW what it was doing.. But you DO NOT. [bootyshak

Actually you show exactly how much you don't know... pure idiot speak. Un metered air into the intake is a VERY bad thing for a motor. I found out from the dealer it has the wrong intake tube on it. Go screw around on another thread TROLL!

Just took the cover off of mine and found that the port is NOT there. You might be better off plugging it on yours.
