You industrious XK8 owners who have cut out the leaking accordian-pleated section of your intake duct and replaced it with a section of flexible silicone tubing that is glued and clamped in place - where did you purchase your silicone tubing?

This morning I hit Pep Boys, Advance Auto Parts, NAPA, and Lowe's Home Improvement looking for silicone tubing. Nobody carried it, nor could they refer me to a store that does. Very frustrating....

Do any of you still have your silicone tubing's package with manufacturer name and part number? Any specific details would be much appreciated....

 

Several people have reported success (on UK forum) by using Shoe-Goo and applying it with a paint brush - all over the accordian section.

Haven't tried it myself.

 

This tubing ,in various sizes , is used exclusively in aircraft and is available from Aircraft Spruce and specialty among others . I used it when I replaced my aircraft engine . It is a Mil Spec. product ( FAA approved) and will tolerate hi temps and a great deal of abuse.

Mine is wrapped with self-fusing electrical tape like this stuff:

McMaster-Carr

It's been on there for at least a couple years and works great.

There is also intakehoses.com in addition to a multitude of ebay vendors. Also any shop specialising in turbo cars will have them.

 

Is it a jaguar xk8/r thing that owners are so tight on the money!
This part is dead cheap at the dealer, so why fool around and bring the value of your car even further down by doing cheap repairs to already cheap parts.

Would you buy a car with ducttaped together parts, or parts originating from walmart!

 

There is a performance benefit from replacing the corrugated section with a smooth section.

Some people also like the cosmetics. Take a look at some of the underhood pictures of some members like JagXja.

And finally, there is no need to cast aspersions on the finances of any member of this forum.

 

"Dead cheap", Jochem00 ? Sorry, but $125 for an inferior plastic part that should sell for no more than $20 does not qualify as "dead cheap" in my book. And I'm not looking for just an inexpensive repair - I'm looking for a permanent improvement....

And by the way, I did indeed purchase a new XK8 intake duct from our local dealership to replace our factory duct that failed. But when the new duct invariably fails as well, I want to have a better design on hand to permanently fix the problem....

Shoe goo, electrical tape, etc. will not help me, guys. The first thing I did after removing the factory intake duct several weeks ago was to cut away the failed accordian-pleated section, so in order to repair it a new section of tubing will be required....

 

I thin it is necessary to hire a good contractor instead spending a time on thinking how to do this.

 

Get silicone couplers/reducers, metal tubing, clamps and optionally a cobra head adapter from the site mentioned above.

You can choose to remain stock diameter, or upsize. The upsizing can be only along the longest accordion section, or all the way to the TB. That last option requires a cobra head.

 

Michel,
I've no idea what your comment means but do please visit

and introduce yourself so we can say hello.

 

plums,

I have corresponded with the folks at intakehoses.com. I had decided to use rubber hose connections for maximum cost-effectiveness. They have no rubber hoses with the proper outside diameter that I need to tightly fit inside both pieces of my existing hard plastic intake duct. They also poo-poo this idea because there would be nothing inside the rubber hose connection to allow it to be clamped down upon....

If I attempted to reattach the two original intake duct pieces via the silcone hose route with couplers, adapters, etc., I would probably wind up spending more money than I did for the new stock Jaguar hard plastic intake duct I purchased and installed about a month ago from our local dealership ($117 plus tax). I see no point in doing that since my wife's XK8 is simply her daily driver, not a performance-oriented XKR....

So for the time being I've bagged up the two intake duct pieces and stored them on one of my garage shelves. If I stumble upon a cost-effective flexible hose that solves this dilemma, I'll post my solution here. In the meantime, my wife's XK8 has a new stock Jaguar intake duct that should work just fine for a number of years before the Achilles heel accordion-pleated section weakens and cracks as they all eventually do....

 

Rubber hose inside the existing ductwork would be just silly. It would reduce the cross-sectional area of the duct. The reduction would probably be worse than the effect of the accordion itself.

Your query asked for a source for the silicone hose ... period, there was no mention of cost considerations, or that it was for what is effectively a spare.

As intakehoses.com seems to be competitively priced it and you don't like their prices, it would seem that silicone components is not the route for you.

Just so other readers are not scared off, careful examination of the online catalogue suggests that replacing the accordion section of the intake would cost somewhere around $25 including clamps if the reader is satisfied with maintaining the original dimensions. Shipping cost not included.

 

Not to be repetitive, but I don't see the problem ! Aircraft silicone tubing is wire reinforced and comes in single or double wall sizes. Price is not prohibitive and it is readily available. So what,s the problem ....something I am not aware of ????

 

plums,

Please explain your approximately $25 estimate to accomplish this repair using components obtained from intakehoses.com. Exactly what components are you proposing to bridge the cut-out accordion section? Please provide the associated part numbers so I can investigate further. Thanks....

 

Would not even contemplate doing such a cheap fix, but if you really have to ebay sells all sizes of silicone hose.....

I do have an aluminium one I am selling cheap as I dropped it if anyone is interested, you can't really see the dents as they are on the bottom but apart from that it is fine

 

The site is available to anyone who cares to look. I have no interest in visiting the site for the fourth time. I have the parts picked out for a upgraded version which will cost more than $25, but I stand by the accuracy of my statement that specifically replacing the accordion section only in the stock diameter can be done for approximately $25.

 

I've never had to modify or repair an intake duct before so I have no familiarity with these silicone hoses and various connectors to make them fit in circumstances such as ours. Since you apparently have such knowledge, I asked for your specific assistance with components and part numbers. When I have knowledge and the associated part numbers regarding a specific topic that someone asks about, I try to provide that information because I realize how much it can help someone who is unfamiliar with the issue. I'm sorry to learn that you simply cannot be bothered to do so in this instance, and I promise that I will not ask you again....

 

Come on kiddies . . truce

Now shake hands, or you'll both get a smack on the bum.



Btw, XKRacer, is that aluminium item for XKR's only, or do you have aluminium ones for the XK8 as well?
And if so, any piccies available, and prices?

 

Same pipe does XK8s, Rs, and will do XJs as well although I have not fitted one to an XJ before but can not see no reason why not......

The slightly dented one is going for £100 which is less than half price plus shipping


Looks just like this one




Found another pic with an XKR
