Dent in Manifold

[Curley]

Anyone seen anything like this before?

 

[Barron]

supposed to be like that

 

[Curley]

Sweet. Looks a bit restrictive

 

[Jonny1*2]

hmmm, never noticed that when i've been under mine, but might be wrong.

 

[Chrisjk]

Some do, some don't, it's to clear the arb.

Fooking renault! Thats losing me valuable horsies

 

[Jonny1*2]

lol, i doubt it mate.

 

[172Ben]

LOL could you not tell by the pic why the perfect curved shaped dent was there?

I doubt its losing any power either mate

Yes but a few people have said theyve not seen it before so thought id ask on here. It looked as if the manifold has hit the ARB.

It was a joke about my horsies

 

[murcod]

Mine's like that. If you look closely you'll see it's been made that way from the factory.

 

[Mark One]

I'm pretty sure they don't come from the factory like that, but 70% of them end up like that after they hit the ARB a couple of times

 

[Tigger]

Are there any marks on the ARB under the manifold?

nope it certainly comes from the factory esp UK one's are like that.

 

[murcod]

Do a search and you'll find old posts on it. I initially panicked thinking it had somehow been dented!

PS: Most people don't realise their manifold is like that because you literally have to get your head right underneath that section of the exhaust to see the indentation. I certainly had no idea until I got right under while I was investigating something else. I had even previously measured/ photographed all the exhaust pipe section diameters and not noticed it.

They can't come from the factory like that surely not!!

I've seen two 182 manifolds with out the dent there.. It will be cussed by excessive movement e.g. worn engine mounts, worn bushes.

You beat me to it, I would have thought it would have been bent because of the worn mounts ect

Mine is fine

 

[Reyes]

Yeah. Normal. Mine was like DAT INNIT BLAD

 

[DannoTheGreat]

iv never noticed, i'll get out an have a look in a bit!

Nope they come from the factory like that 110%, but as said some have it some don't feck knows why. Dent wouldn't be as well formed from the arb it'd be more localised, I would imagine they've been heated then deformed.

 

[chrissyp]

I thought mine was damaged also when I bought the 182 manifold for my 172 till i checked the next 182 that came into work then realised that was the same.....then the next one I had in was the same also.

 

[Martin_172]

as said above their are batches that didnt have it but most of them come from the factory like that. i would agree there is power to be had from removing the dent, if you would notice the gain or not however is debatable!

Sorry, i purchased an brand new one that was put on with the cams (C&B ofcourse) , came straight from out Dieppe Connection , WITHOUT the dent.

I rest my case!

Renault would not put a dint in a perfectly good manifold at the factory LOL!

 

[franx]

^^ nono, you're getting me wrong ! Renault HAVE been making ones WITH + WITHOUT the dent ! I have also seen the ones WITH the dent, and sure they were made like that

I'm thinking the dent is made there because of the "all known banging on acceleration"-thing going on with these cars. Just look at how close the manifold comes to the arb (esp. without the dent)

 

[Jamie]

Awesome.

I sold a manifold but had to refund it due to me thinking it was damaged.

This thread just saved me £180.

Awesome.

mine did brand new

i rest my case

def not damaged. it's kind of like the different inlet manifolds going round really

 

[Jamie]

Yeah i did see it when I sold it but when challenged I thought i may have had it wrong so quite happy to see this as it means I have just got £180 back. Result.

 

[ripp]

mine is the same, but for sure it came out like this from the factory, I've just installed a brand new ARB and the old one was fine in the area which could have been in contact with the manifold.

 

[fmp_]

just to add my findings.... 2 182 manifolds i have had (one on the original car, one bought from a breakers) both have dents in them.

Although there is a bit of confusion with it, seeing as some did and some didnt.

When i posted pics of my manifold after it was ceramic coated, i had the so called CS 'experts' telling me it was damaged. How wrong they were (and still are on many subjects these days... but thats a different story!! haha)
