I was hearing sound coming from the engine compartment that didn't sound quite right. I let the car cool for a long while then took my heat shield off. Started the car then ran around to the passenger side and felt around where the downpipe fits to the turbocharger. I could feel air coming from the drivers side of the DP/TC. Checked all the nuts and bolts to see if everything was snug and indeed it was. Any ideas on whats up? Thanks.
