Re: **Loose intake butterfly screws**
If your xtrail is still under warranty do NOT touch them and tell the dealer to approach Nissan Australia for an authorization to have this done and say that you will agree to pay the charge to have them checked-out, if that is what you want, it'll cost you around $300 or so to have the screws checked out and loctite applied.

Re: **Loose intake butterfly screws**
Hi,
Is there any update to this topic? We have a 2004 TI which has only done 30000K and we are about to go on a trip from tassie to WA. I need to make a decision before we go on to fix or not fix these screws. As a retired automotive engineer who has workrd in the auto industry for 40 years i am absolutely astounded by this situation. I have never worked for Nissan but have had several Patrol's over the years with never a serious product problem.
Its such a stupid design error which is so easily fixed it makes no sense why Nissan would not spend 2 hours per vehicle to fix it. Any ideas why its OK for a USA fix but not esewhere?
Has anyone struck problems in doing the fix?
Thanks,
David G.

Re: **Loose intake butterfly screws**
David,
There are no updates on this from Nissan in terms of issuing a formal recall to fix it or implementing the preventative measure, so it is now entirely your choice and call to make.
You can either do the fix yourself which has been explained earlier in this thread or ask a dealer to do it for you and it will cost around $200
I guess there wasn't enough push from the public on Nissan to take this defect more seriously, in the US however they risked a class action, so that is why this exact fault was promptly fixed. Not enough voices in Australia to be heard it seems.

Re: **Loose intake butterfly screws**
At the moment I am still talking to Nisan Australia, I will post the whole story and results at a later day.

Re: **Loose intake butterfly screws**
Did the butterfly screws myself yesterday arvo after lunch.
I bought the split manifold gasket and the throttle body gasket for about $43 the other day.
Doing the screws themselves or even getting the manifold apart wasn't hard or very time-consuming, it was all the wiring harness clips and fiddly things like that !!
Car runs OK, didn't need to do the Idle air relearn or anything, even though I cleaned the throttle body.
End 4 out of 8 were "tightish" - not what I'd call rock solid.
Middle 4 out of 8 were loose, but not rattling kind of loose yet.
I was relieved to see 8 still there.
They all seemed like thay had been fitted with some sort of thread locker, but maybe it wasn't working perfectly??
Now I am confident and very happy that they are done with the hi-temp thread locker and tight, the manifold should never need to come apart again!
You wouldn't attempt this if you are not PERFECTLY OK with pulling parts of your engine apart and being confident about getting it back together and working in one go. You need to have all tools on hand, this is not something you want to stop half way through.
What surprised me was the amount of liquid oil around the gasket where the two halves of inlet manifold split - right at the butterflys. The oil has pooled in ever little nook and cranny that it can. My oil breather pipes were still clean, so obviously the oil is still very much vapourised in the hoses and condenses in the manifold - I feel an oil catch can coming on....
By the way, a few of the bolts holding the two halves of manifold together showed signs of corrosion due to water getting in (or sitting). You'll need to give them a good wire-bush up and refit them with a nickel anti-seize - use ordinary grease if you dont have never-seize or copper-coat or something. If you're planning on doing some reasonable amount of work on your own car, the never-seize is invaluable and will last many years.
Also changed the pully drive belt - see the related thread somewhere else.

Re: **Loose intake butterfly screws**
Good stuff Shawn. Better be safe than sorry, but as you say, this is not the typical and easy DIY type of method that anyone can try and do if they're not confident enough. One wrong move with these little screws could potentially lead to a much bigger job if they fall through inside the engine.
An oil catch can is a must and I have demonstrated that in the oil catch can thread, all this collected oil would be sitting somewhere inside the manifold had it not been collected by the catch can.

No way! They will never agree to do such a thing.
