Exhaust Fitting Problem

[Guest Colin45]

Hi all,

 

I'm having a problem fitting a new exhaust, i managed to hack the old stainless steel gasket off which fits between the manifold and the downpipe but trying to get the new one on is a nightmare. I tried washing up liquid but it just won't go the manifold.

 

The haynes manual is no help and I have managed to mangle the new gasket up by hitting it with a mallet to get it over.

 

Do you just put it on loose and when you tighten the spinged fittings it pulls together.

 

Any advise would be appreciated.

 

Thanks

 

Colin

It took me ages to do, you have to remove all of the old gasket, and then the new one should slip straight on

I did manage to remove all of the old one but the new ones just too tight, it will go on at one side but the other just won't go over and damages if you force it which I had too.

 

Anyone any ideas.

 

Thanks Colin

Trick is to clean up the surface on the manifold rigourously, where the gasket slips over, particularly the edge where the gasket first needs to go on. Remember mine was a right pig to do last time, but with patience it did eventually go on. There is a chamfer on the gasket to help, but it's difficult getting it square-on when access is difficult. First time I changed it, the manifold was off the car, & job was a doddle!

Whatever, you shouldn't have used a mallet! Despite appearances, the gasket is actually pretty soft & easily damaged, so best to be sure any damage you've done will not affect likely gas-tightness. Also if it's distorted, it will be more difficult to fit.

Thanks for the advice, I have eventually got it on and the fun and games began with the spring loaded fittings. Time will whether it leaks as I've not started it.

i find that the genuine peugeot exhaust fitting kit is easier to fit than cheaper kits

 

as stated though there is a knack

 

fitting the springs and nuts is easy too, if you have some mole grips to hand aswell

sorry to hijack but is the gasket actually needed?, i plan on fitting the downpipe to my 6 manifold rigidly without the springs and fitting a flexi pipe lower down the downpipe for vibration etc?

 

will the flange not seal properly without the gasket? even when not using the springs etc?

[lagonda 42]

The engine is flexibly mounted...and despite the lower mounting, still rocks back and forth a fair bit. The manifold/downpipe seal is rounded so it fits in the cup formed in the top of the downpipe...this is so that it can maintain a seal despite moving. The springs hold the assembly together very tightly, so that a good gas seal is maintained despite that movement, and allow that movement.

Yes you probably could assemble it rigidly with gun gum instead of the gasket....but would imagine the downpipe would hit the body shell regularly. Also the exhaust manifold would be liable to crack....wouldn't risk it.

are these available at pug? also i would need the springs and bolts etc as mine are buggered. are these also still available?

 

anyone got part number by any chance?

[welshpug 1,657]

yes they are, they come in a kit for £15-18, more often than not in stock at most dealerships, motorfactors also stock them but I find the quality far better in the o.e parts for not much more cost.

If you have a Quick Fit near you they have a box full of the springs/bolts/nuts etc. Give them a couple of quid and i'm sure they would be willing to hand a few over. Worked for me.

just got off the phone to pug for one of these kits for my Mi. Probably the only part I've ever bought off pug that they actually had in stock already! £25ish inc vat but that's worth it for OEM quality parts.

[lagonda 42]

I use Arvin/Timax exhaust parts on mine...the gasket & fitting kit is £3.18 + VAT + P&P from bupartsby. Had no problems with the quality of these parts.

The exhaust itself was substantially cheaper than the exact same item (make & part numbers) from my local motor factor...despite me having a discount card with the factor, AND paying P&P for delivery. Ridiculous really, but no brainer....pay £40 more at factor & have to return to collect as not in stock, or press a few buttons, have it delivered quickly to your door and pay £40 less!
