Hey Guys,

Couple days ago I used de-mist on the climate control to clear the windscreen and ever since, moisture/steam has been rising from the air vents along the base of the windscreen, fogging it up and causing water to drip from the glass, I cant see shit. Has been happening for a few days now, smells nasty and making it pretty difficult to drive.

I assume its related to the A/C -Condensor or whatever, just wondering if there is anything I can do to make it stop without having to take it in to the shop.

Any help appreciated, cheers.

Tristan

Have you checked the coolant?

Could be the heater has a pressure leak... but I would imagine you would notice a few other things at the same time.

Can you feel if there is any air flow from the vent? If so, is it hot or cold?

The radiator coolant?

Yes the air flow is hot, probably why the window *fogs i suppose

Like eiji said it sounds like a small leak from the heater core, maybe check the coolant level, get it pressure tested and see if theres any coolant leaking from the heater box, if there is then its heater box out, big job on most cars not sure about yours though.

Best thing to do is get a pro to take a look at it. Get an accurate diagnosis :D

Thanks Guys,

Seems I can bypass the heater core fairly easily by connecting the inlet/outlet pipes together. Might try that rather than spending hundreds replacing it. I found a tutorial on replacing the core without having to remove the dash, will try when I have the time.

Cheers

In case anyone is interested, I have bypassed the heater core and the problem seems to have stopped. However, as the heater core was rusted out, the coolant/rust is now throughout the cooling system, I will need to flush the system.

So for future reference, if you notice a problem with the heater core, dont leave it.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
