Fitted Decat But Its Blowing

[Faxo]

As title, its blowing at the manifold join! Its one of the most fiddley exhausts ive fitted, i cant seem to get it to seal! Its a KTec one too so should be good fit id of thought?

Anyone else had this problem?

 

[Justin182]

I spent many hours under my car trying to solve blowing from a sportscat and eventually gave up. I just dont think its a good design on the clio.

 

[Faxo]

Might take it down the dreaded kwik fit?! What you reckon, they've gotta have most experience fitting exhausts!

 

[Justin182]

Yeah, in there defence i went there because i just couldnt be arsed getting the axle stands out again and they did a better job than me as they had proper tools and better clamps, also helps if there have more than one person to push the parts togther. Just make sure you catch them when they are quiet so you get the better guys helping.

Still wouldnt go there for anything else though.

You may just need a new Gasket kit... Its not Cheap but I am getting 1 soon as my car is slightly blowing from that join on my 182

I got a cat fitting it from the dealer recently. iirc it was around 25 quid. came with o'ring seal, springs bolts and nuts. I'll dig out the part number.

For 172 yea?

If its blowing at the manifold join then the above kit is definitely what your after. It shouldnt really blow. I've had experiences with a few of those renault manifold downpipe joins and they seem fine

which i think is cheaper than Ktec do em

joking arent you - you are a technician and you are going to take an exhaust job to quik fit????


look at where its not crushing the gasket and see whats what might have a high spot etc

 

[Bluebeard]

one of my 172's had a decat from Ktec and tbh in 12 months of owning it, I could never get it to stop blowing.

Personaly I HATE other people working on my cars

same thought of it makes me cringe lol

 

[Matteh]

mines blowing at this joint too... does the renault kit include any paste? or is it just that metal gasket?

quite annoying

Agreed

 

[mattjk]

I hate the paste it just gets hot cracks and then falls out, definately a temporary fix.

 

[Fred@BTM]

silicone doesn't

 

[mattjk]

The only that springs to mind about silicone is bathroom sealent and my mothers breasts

Neither would be suitable for sealing an exhaust.

 

[Fred@BTM]

exhaust silicone is exactly the same as the bathrrom stuff, just handles heat

 

[Matteh]

you can seal it with exhaust silicone?! (never heard of it)

where does one acquire such stuff?!

 

[Gray]

hahaha at the "exhaust silicone" comments..

Any kind of normal silicone will seal an exhaust, better than all that paste rubbish aswell!

 

[mattjk]

Edit: Just read it properly, where inded can it be purchsed from?

 

[Matteh]

I'm confused, are people being sarcastic? :dapprove:

cover the metal gasket from the downpipe to the manifold with silicone? :dead:

 

[Flash Arghhh]

i've fixed mine with silcone once. work paid for it hehehe:rasp: so don't know where to get it from, but try unipart they normally have stuff like that

 

[Andyman]

Manifold to cat should never be sealed. Its designed to move about (obvious)

The silicone thing is NOT a joke. Have a search

 

[Hutchie]

i think the silicone stuff you are talking about is actually exhaust paste but should not be used infront of the cat, or where the cat has been

 

[Andyman]

No!! its silicone not paste

Do a search. There's more info on this on here

 

[mattjk]

I dont wanna search I wanna go over the same thing again and again

 

[Gray]

haha its bog standard silicone... nothing exhaust related!

Silicone is the best exhaust sealent i use/can think of, the exhaust paste you can buy just dries up and cracks after awhile

 

[mattjk]

Reckon! Bog standard silicon are you sure it can take those temps?!?!

Liquid Gasket, been around for donkeys years. Used to use it on my Yamaha RD125LC when I used to put my go faster Micron exhaust on. Never hardens, remains flexible and very easy to remove. Costs less than a fiver from most Motor Factors.

interesting stuff about the silicon!

 

[Fred@BTM]

yoz will sell you a tube, you just need a silicon gun from B&Q (about £3)
