I tackled the nagging P0171 and P0174 (lean in bank 1 or bank 2) with a fairly easy fix. I checked this forum and found that one of the usual causes was air leaks between the MAF sensor and throttle body. I checked the air duct on my car and sure enough it had cracks along the bottom in the bellows section. Instead of buying a whole new duct ($$??) I cut out the bellows and installed Nissan part number 16578-CA09A, cost $20. Much better than the original set up. As an added bonus it makes the air filter access easier and lessens the risk of creating a leak after you check it.

 

I have been dying to use that emoticon

 

Don't need no stinkin' picture!The repair is so straightforward you don't need one but for the mechanically challenged here's a mental one: Replace the failed cheap plastic part with a nice new rubber bellows like it should have been made to begin with.

 

Was this for a XK8 or XKR?

 

here's the part....

 

The last induction pipe I fixed, I made myself, I do that a lot........

There's no way a cheap piece of convoluted hose will get in one of my engine bays

 

xkracer, make me one...from TB to MAFs PM a price!

 

No worries Matt I can do that, just let me know if you have a breather coming out of the induction pipe at the TB end? Or post up a pic, there is also a slight chance the US spec ones might be slightly different but dimensionally they will all be the same.

 

I am very interested in that set up as well. My XKR has the breather where the induction tube enters the TB - it is 90 degrees to the TB opening. Do you also have it routed into the fender well for cold air?

Please excuse the dust, ran through a little dust storm here.





As far as I have been able to tell the induction pipe is the same for both Euro and US XKs (Rs and 8s are different I was going to put an XK8 pipe on to eliminate all those parasitic sound control tubes but your set up is so much better)

 

XKRacer

Very sharp looking setup. I would also like one for a 2005 XKR Coupe. Please email the cost and I will get back with you.

Thanks

Not a problem I can make a few up.


Looking at Marcs, I reckon he could do with some strut caps and aluminium strut braces as well

 

I think I Like this idea.

 

No goofy baffles on mine, and ive got the same breather stub as marc. Crappy pic attached from my phone. Strt brace? I didnt think that was possible?

 

You are correct, strut caps would be an excellent addition and as Matt mentioned - Strut brace? Tell us more!!!

 

OK Strut brace might of given you the idea of the, across the engine bay connecting the 2 together.......And your are right, it is impossible, there simply is not the room under the hood.

What I have done is recreate the OE steel tube items you see fitted to convertibles, going from the strut to the bulkhead. These are made from solid aluminium (7/8 dia) and fit to the strut via a stainless ball joint.
I do have pics of some fitted to my coupe, quite a few people do not realise the holes the convertibles have to fit the brace to the bulkhead are also present on coupes so can be fitted.

When I am back at work on Monday I will take a pic

 

I think I see what you mean, the brace at the strut tower back to the firewall...at about a 45-deg angle. correcto?

 

Correct

 

I would like to know what your breather tube costs also. And the wire mesh louver inserts for XKR hood, like MarcB's. What else to you make?

And, I had wondered to myself whether there were threaded holes on the coupe for mounting the convertible struts/supports as I thought it could only help...thanks for answering that too.

 

I will work a price out for you guys, it will be a little more expensive for those with the newer XKs because of the extra breather, just give me a couple of days.
I have a 2004 XKR with the later type so I can do a drawing and produce a few.


Below is a pic of the strut cap and brace, in this pic the brace still needs polishing but you can see how it fits onto the strut tower




@ Steve, you need to have a wander around my website www.paragondesignuk.com basically I can do anything (well amost anything), there is still alot I have not put up yet, it is as with life, a work in progress!

 

Xkracer is a fabricating genious...if it can be made, he'll do it. If he hasn't thought of it yet, I bet he can build it. I'm surprised nobody has asked for those snazzy 'halo' lights.
