Umm, so yeah. Last night I got in my car and started driving home and there was this light tapping sound under boost. I immediately got very scared. But as I tested some things, I found that it was ONLY related to boost...not rpm. I can rev the engine in neutral and there are no sounds.

So today, I went outside and did some investigating. Took the heat shield off, and the compressor outlet elbow and had me a look-see. Nothing special. All the gaskets are there and things look decent.

Now the sound has changed: It's like a screaming chicken is under my hood when I boost!!!!  I don't know what that means  

My main concern is that I won't damage my motor. I'm already in the process of buying an S14 BB turbo, but I'm not planning to put it in until May. So can I keep driving like this?

Please, I need your thoughts.:nervous:
