I just had a bunch of work done on my C4, clutch, LWF, belts, new sound pad, etc. While reaching in the engine bay on the left side to check out the new sound pad I feel a small area that is blowing air out of it. It is not too strong I can close it with my finger. It is kind of like a small port or opening. The opening is maybe the size of the top of a drywall screw. Is this something wrong, is it the SAI port? It is on the left side of the engine. The small hole or port is not on a piece of plastic or rubber it is on the engine block. Any ideas would be helpful. Thanks in advance.

A picture would be helpful.

I don't think I can fit a camera in there. The opening is on the left side. It is blowing air sideways towards the left fender towards the wheel.

Chris, assuming the engine is running when you feel this air "leak" it is pobably just cooling air from that big fan the axx end of the engine. A hole that size is not going to cause overheating. Not likely a hole in the engine block and the SAI crap is under the air cleaner on the other side.

Make sure everything is attached on the heater blower fan. There are a couple of sensors in the tube, & the rubber boots might not be seated all the way.

Upon further inspection the air is blowing from little round port or opening on the heater box/cooling fan. Any more ideas? Is this normal. I just want to make sure its not a vacuum leak.

There is a temp sensor that goes in the round hole, look around the area, it should be dangling somewhere near.

Stealth 993 is spot on. There is a temp sensor that should be installed there. If you have a vacuum leak that massive, the engine wouldn't start. Don't fret.
