Whistling noise at idle

Hey guys, i own a  1996 r33 gtst for the past 4 years. It has a 3 inch exhuast and front mount but apart from that is a stock car. Recently i have been hearing a whistle noise coming from the engine (trying to source where it is coming from it sounds like turbo or pod filter) doesnt matter if it is warm or cold it is always there only at idle.

Since it started the car has also began to flutter. Not all the time but if boost isnt fully built up it flutters when letting off the throttle. The bov is stock and has not been blocked off. 

I have checked most hoses for leaks and havent found anything. I am completely lost as to what it could be and cant find any threads that explain this at all.

Thanks for any help.

If you suspect your pod filter take it off and see if the noise goes away. How have you checked for leaks? You need to pressurize the system from the turbo to the throttle. Your turbo is 24 years old and could be due for reconditioning or replacement.

You have a vacuum leak somewhere, possibly an exhaust leak. Get yourself a piece of garden hose and go listening. This stuff is not so hard.

this is definitely where you start. seems like everyone jumps to the big issues before grabbing the garden hose, or a multimeter and actually running some tests for simple issues. theres not that much piping on a gts shouldn't be hard to find the leak m8. and turbo could still easily be bunged after 5 years. ive seen lots of reconditioned turbos bite the dust early.could even be cracked housing on intake side of turbo ive seen this too. do the garden hose test and shout back...

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
