Wierd noise after fitting FMIC...

[Steve_225]

Hi Guys

 

I fitted a fmic this weekend - Seat Sport kit with pipework from Darkside.

 

I am used to the normal whooshing sound when on boost but now its making a very high pitched noise, the only way I can think to describe it is when you have a balloon blown up, you pinch the edges and the high pitched sound it makes. I thought it might be a boost leak, I have re-checked all the clamps, made sure nothing is loose but it still happens.

 

I have also noticed that the sound of the engine when driving sounds a lot deeper, is this normal?

 

Thanks

could you pressure test it?

[Steve_225]

What would I need to do the pressure test?

 

Thanks

When fitting the pipework, were all the joins free from grease/contamination?

[Steve_225]

I did check there was no grease etc in each join and made sure it was a dry fit?

Sometimes if there's grease or oil it wont seal properly. I had the same issue on my glanza. Took 10 mins to degrease all the joins and it was fine since. What clamps are you using? Jubilee or mikalor?

You need a compressor and a kit with a pressure gauge. the kit is basically silicone pipe large enough to go over the intake ( air filter end or right down on the turbo).

You then put your compressor on the end and fill up the system. put boost leak tester into eBay.

Metal pipework makes more noise than plastic so possibly that

[hutchysrs50]

It's 100% a boost leak, you just need to find where it's coming from!

Hole in the new intercooler?

[JoshH]

Yup deffo a boost leak, mine was coming from the rubber gasket between inlet mani and egr delete.

[vrs'burks]

Boost leak. . .have you checked where the map sensor bolts into?

[Steve_225]

Ok, so it sounds like it is definitely a boost leak and just need to track down where exactly. Only problem is I don't really want to take all the bumper off again etc. as it was a mission lol

 

I used the clamps that came with the kit, they weren't Jubilee - they were more the style of Mikalor clamps.

 

I certainly hope it isn't a hole in the new intercooler

 

Also, how hot should the metal pipes get? I'm worried about the pipe that runs to the egr valve as one of the pipes to the fuel pump runs over the top of it

 

Thanks for all the replies

Pre intercooler the pipework will take your skin off!

After intercooler the cooler the better! It wont be an issue

[Steve_225]

I felt the turbo pipe today and yeah it was hot!!! lol

 

That's good then, I was wondering if it would need wrapping

[Steve_225]

Would this boost leak tester do the job:

If you've replaced all the piping as part of an intercooler kit one of the common causes of the whistle can be where the sensor is mounted, I spent ages on mine taking the bumper off again and tightening joints only to find it was the sensor, drove me round the bend!

 How did you secure it in the end? I have 2 8mm bolts screwed into mine - there were tight but may need checking again?

[mattievrs]

if its the sensor does it have a seal with it> If not, try some instant gasket maybe??

[VRSGAZ 170]

Glad it's not just me then. I fitted my seat sport intercooler and darkside pipes three weeks ago and i am having the same problem but only for the first 30 seconds of driving. I've tightened all clamps and checked the joints which improved the noise but its still not 100%

My thinking was that the noise is from the hot side of the intercooler because its as though something expands and seals the leak.

I just used blue gasket sealant lightly round the seal when I put it on, if its anything like mine was the hole was huge in comparison to the size of the sensor? It's not just a matter of how tight you do the bolts, sometimes the aftermarket finish against the standard sensor just isn't perfect and it only tiles the smallest of gaps to have the thing whistling like a blown turbo!

Do you also have a lack of power when cold? My pd150 does this,

Sounds wooshy when cold and goes slow as anything! Then when half warm the issues resolved

Yeah but only for half a mile or so then it stops and its back to full power.

The car also has a pd150 turbo fitted and has no obvious leaks from the turbo or manifolds

[Guest BigJase88]

Yeah mine does this

Can't get to the bottom of it! Whooshy and like a snail for half a mile then goes like fluff once warmed up! Done it since i've owned it and i've changed almost every sensor

[VRSGAZ 170]

Yeah it's really annoying because I find myself going the long way round when I leave the house to avoid going up hill so not to put it under any load during walm to avoid it doing this thing

The fitting was quite tight when i pushed the sensor in, but I will take it out and run some sealant around the flat edge and re-install.

When first fitted I only heard the noise twice, but now its everytime im on boost - whether hot or cold.
