Had the headers fitted the other week, and the gasket between the turbo up-pipe to manifold has gone.
I presume it was just a defective gasket??
The headers weren't an a1 fit but almost. When i tokk the gasket out after undoing the two bolts the up-pipe sprang back leaving a gap of around 3-4 millimetres.
Should i go for a better quality gasket that is quite thick, or put two of the same type gaskets on??
Any suggestions on good quality gaskets??

 

Just weld the damn thing as mine kept blowing every few weeks!

Banny

 

If the flanges don't align quite right then it could have left a tiny gap and the gases burnt through it making it worse.

Would try using a bit of non-silcone exhaust paste as well as a new gasket: Makes sure its oxygen sensor and catalyst safe; it does exist, although alot isn't so read the label before buying.

Failing that, if they are new headers/up-pipe; I'd send them back as one of them hasn't been formed correctly. Quite typical of aftermarket performance exhausts I'm afraid.

That is a very cheap and nasty gasket, that is why. Buy an OE one and it should do a lot better.

 

Cheers folks, but i think the OE gaskets are thin stainless and there is the 3-4 mill gap?


If i welded it would i be able to take it off again, as abit tight space.??

 

But you suggest that when you tighten the bolts it all pulls together? I take it the uppipe has a flexi joint?

The OE gasket has a crush ring (the one in the picture doesn't) which means gasses can't escape through the thin metal layers that make up the gasket - if sealed correctly.

 

Flexi joint is cheap and nasty mine is solid

Even if the gaskets blown!!

Just bought 2 with the centre crush rings in them so should be fine in a bit.

 

Use a OE One. If there is a gap as your saying sound like its not the right part

 

I had the same problem with my GT Spec headers, i went through 4 gaskets inc subaru ones, in the end i got a kit from RCM and have never had a problem since.

 

The header set is Japspeed. Think prob just a poor fit as only slightly mis fitting.

 

Out of interest. Can you smell exhaust fumes through your vents with this problem. Expeically when sitting stationary?

 

Not that i've noticed?

 

get original subaru one they £8
I had the gap 3-4mm you are talking about on mine and made a stainless steel spacer at work got a spare if you want one. if you tighten up the gap without the spacer you are removing all the flex and it may crack or just blow again.

 

had the same problem for the past 6 months cost me a fortune in gaskets
tried dealer ones and aftermarket mine has got a 8mm gap and thats with standard headers and up pipe got three gaskets in now and a load of exhaust paste still blows got used to it blowing now

 

do you want a spacer may have 2 spare ?

you will get extra lag with it blowing as well

 

Phone RCM i had the same problem, they will supply you with a new gasket and bolts, it will solve your problem

 

Yes please Ian, YHPM

 

Who are RCM

 

Just tried two decent quality crush type gaskets and a bit of exhaust paste and it's still blowing !!!!!!

Ian! Put me out my misery!! Can i buy one of those spacers from you???

Thanks folks

 

Trying to sort out a problem I have with fumes coming into the car myself and thought this might be the same as me. Good luck with the gasket though!!

 

I notice you drive a wagon.
Are you sure fumes are not coming in from the boot area?
I only say this as i had an estate car and due to the exhaust being straight fumes would come in through the boot.
Just a thought
