Intercooler boost pipe leak

[Gunner 66]

Hello
I have a whooshing problem coming from my intercooler and not sure what side its coming from any ideas?

 

[ajlsl600]

Pipe split, hose clip or fixing loose split in cooler or manifold. leaking manifold seal or gasket

Get the undertrays off and have a gander

 

[Gunner 66]

Already have done but nothing garage guy said that it was coming from the turbo side of the intercooler as he reved the engine and heard a rush of air from that particular point

Typically split hose, usually in the inside of the bend, often hard to see till hose removed.
If it uses henn clips to hold the hose (the end of the hose will be metal) there is an o-ring inside that can leak (henn clips can be removed with the correct tool or with patience and care a screwdriver can pop the wire clip up).

 

[Gunner 66]

Ahh Right ohh.
Yes it's a one of mercedes up grades instead of using jubilee clips' would that pipe or hose be on bank 1 or bank 2

 

[LostKiwi]

You don't have bank two. Bank 2 is only on V6, V8, and V12 engines.

There are two hoses. One in, one out. Follow the pipework from the turbo to the intercooler then back from intercooler to inlet manifold.
Hoses are the biggest rubber ones in the engine bay.

Not all cars use Henn clips.

Oops forgot sorry '
I removed the front bumper today had a route around saw the hose from the turbo to the intercooler and the other hose from the intercooler to the inlet
It's a tight squeeze so couldn't realistically get my hand up to check it out.

As long as no fire risk u cud have someone on accelerator boot it and spray some wd 40 about the place and see if you see the spray getting diverterted. Or just bite bullet and remove them car makers only have interest in how easy kit is to install on the assly lines, don't give a shxx how much hassle for u or guy ur paying.!

 

[Gunner 66]

Okay I'll give it a go a bit later many thanks for all the info

 

[LostKiwi]

May not work. Often the split requires a bit of boost to open up and you can't generate enough boost while the engine isn't under load.

 

[Gunner 66]

Or take both hoses off and renew them both that should cure the problem.
I'll see if I can send a pic of the hoses accsess permitting.

Yes that would fix it but you may need a defibrillator when you see the price.

 

[Gunner 66]

OMG how much are we talking about?

 

[LostKiwi]

One boost hose for my R Class was £187 from memory.

 

[Gunner 66]

God knows what it'll be like for my c class then just have to check all the points of the hoses and see what's going on with it

 

[Gunner 66]

Hi all
I've just checked the hoses from the intercooler one to the turbo and the other one to the inlet. The one on the inlet is loose any ideas to over come this problem?

Need to replace them for a upgraded hose with the clamps the normal mercedes clips are crap and will always leak I replaced my outlet hose last year and it popped this year under boost thought I blew a tyre then car went into limp mode. I have the replacement with the clips coming but they don't last so trying to find a shop that sells the upgraded pipes with the clamps, an American YouTuber I watch fitted them and says its way better performance. I'm planning on getting a remap soon to so the pipes will need to be better than standard.

Can't see why replace boost hose if undamaged, proper clamp yes.

Because they go bang my last standard one lasted 1 year and I have not yet done a remap. Better to be safe than sorry and the clamps won't go over the clips on the standard hose unless you cut the metal part off then it will be to short too.
