Random hose
 

My engine seems to be misfiring! It's recently went in for a new clutch! On inspection there is a hose coming from the top of the inlet manifold! It's only about a foot long and Is sucking air! But I can't see another hole or clamp where it would go! Could this be the cause of my misfire? All help would be appreciated!
Cheers guys!

Probably will be the cause of the misfire and you should address it as soon as you can before driving much. Unmetered air will be entering the manifold and will potentially cause the fuel mix to go lean at light loads and very rich on boost. Can you take a photo? Is it just a thin hose or a larger one?

Random hose!
 

That's what I'm thinking! I'm away from home for the weekend or id get my mate to have a look! Il take a photo in the morn as its to dark where I am! Id say it's medium about as wide as a 5p! Runs straight out the top of the inlet manifold down the back and out the right side! It's making a right hissing sound! That's how I noticed!

What year is your car mate?

1997 uk turbo!

Same as mine then. Do you still have the standard dump valve fitted? It maybe belongs to that.

The car is standard! Is the dump valve not on the left as you look into the engine bay!

No it's on the right at the corner of the intercooler.

I've got pictures but unsure how to load them on here! Lol!

Open a Photobucket account for free and use that. It's dead easy to do, just copy the link for the photo and paste it in a post on here.

Yeah I'm pretty sure you'll find that should be connected to the dump valve which is connected to the large rubber pipe at the bottom right of the intercooler.

Your valve will be like this, loose hose goes on the part arrowed

That's spot on! Only problem that little nipple was stil in my hose! That's why it didn't look like anywhere for it to go! Shouldn't be to expensive for that tho!

Ah crap! The plastic has broken off the valve then? You can pick those valves up off eBay for a few quid, even some of the breakers here too.

Thought so! Might upgrade it now tho to a better one! Might as well if I have to replace it anyway! Thanks for all the help tho! I appreciate it!

To be honest I'd stick to the standard valve, they're good for up to 1.7bar boost and won't mess anything up! I have a Turbosmart VTa on mine at the moment but I'm taking it off to fit a standard valve. Just makes more sense to me.

What would it be called on eBay? I've searched dump valve and only comes up with after market ones!

I was looking too, don't actually see any on there at the moment. Well, there's one but its £65 lol. I just searched Impreza recirculating valve.

Contact some of the breakers on here or else put a post in the wanted section.
