Hello All,

I boost leak tested my car yesterday, and got all of the leaks taken care of that were in my power. However, there were 2 strange leaks that I couldn't take care of, and I was wondering if somebody could shed some light on them.

The first leak is out of the IACV. (This is a B16 for reference) The air seems to be coming out of the black plastic cap at the end of the IACV on the driver's side of the car. Is this unheard of? If I replace the IACV, will this leak disappear?

The second leak is coming out of the compressor housing, along the edge that the front of the compressor rotates when you clock the turbo. (Sorry, I don't know the proper name for this, but it is where you loosen the bolts to rotate it)

Can anybody tell me if these are terribly abnormal, and or are a sign of something bad? Thanks!

 

OK, after looking into it a little bit, it looks like the compressor housing leak is not abnormal, but I should pull the compressor front housing off and check to see that there is a gasket there. If not, it seems as though people have been told and are suggesting that you use RTV to seal the housing.

the IACV one has me stumped though!
