After reading a post here about potential problems with butterfly screws coming loose in the intake manifold of the X-Trail, and after some further research on the internet, we decided to have the problem solved before it happened. The job took an hour for our mechanic. The screws were still tight, but they were unscrewed, Loctite applied and screwed back in.
This cases where the butterfly screws have come loose appears to have been mainly in batches of the Sentra(Nissan) engines in the USA. But some must have slipped through to Australia as it has happened here as
well. And with the little softroader now being out of the warranty period, rather than have to fight the manufacturer for compensation should such an even occur, rather nip it in the bud and repair the potential fault. Haven't got the bill yet but assume it to be around the $120 mark. We had to replace one of the gaskets in the manifold and they aren't cheap!!!
SWMBO is very happy again...lol Its her little car.
Cheers

Hi there Willem, not sure how true it is but have also heard of the cat convertor blocking up causing engine failure in the way of going bang. Now how true this is Im not sure. Also not sure if yours is manual or not but the auto's are cooking themselves when used in the sand. My neighbours went bang as he is looking at 4k for a rebuild.Apparently they are suppose to revert back to 2wd even when locked in 4x4 and should give a light on the dash/tranmission console that it is getting hot which his didnt do and went bang had to get dragged off
the beach by another neighbour in his pajero. He has been fighting with Nissan with what looks to be a no win situation. He is talking of taking them to court as the light didnt come on to warn him. We'll see what happens. If yours is auto and you take on the sand might pay to fit an additional tranny cooler although I would imagine you take the patrol. Not bagging the vehicle in any way I reckon there a brilliant car and plenty of power on tap 125kw's if Im correct just giving you some tips on what I've heard one a bit like pub talk the other, tranny 100% truth. Regards Steve M

Stephen,
With the cat converter, there are two of them. The first is in the exhaust manifold, very close to the motor. I understand that the stuff inside can fall apart and somehow small quantities get sucked back into the motor, causing the bores to score and they start to consume oil. In the US, you can buy extractors that get rid of this problem.
As you say, great little vehicles. The pre 2006 models are 132Kw and my wife's Xtrail gets 8.2 l/100k every trip. Ours is a Dec2005 build, so we're hoping these issues were solved. But the 4wd mechanism is too complicated for my liking - I prefer to do the thinking.

Hi Stephen
The Cat Converter was replaced in a recall. There was also a recall on the Fuel Filler nozzle into the fuel tank..Something like that.
Our Xtrail is only a town taxi and is not be driven in sand or anything like that. I am
well aware of the overheating problems as ours is an auto. We live in the country and drive lots of gravel roads. The auto 4x4 mode is good for the missus to use and it makes the little car very sure footed.
Real 4x4 stuff is the domain of the mighty GQ...lol
Hi Phil
" I understand that the stuff inside can fall apart and somehow small quantities get sucked back into the motor, causing the bores to score and they start to consume oil." Them's the butterfly screws I am talkng about"
Ours is a 2003 model and has now done 61,000km

Willem,
They are two separate problems. I know both the precat and the butterfly screws were recalled in the US, but wasn't aware of a recall of either in Aus.

She'll be wright as you said preventative maitanance is what its all about especially when you've been given a heads up first. Regards Steve M

Just heard from the dealer that the car is finally up and running, after having the short block replaced, as the damaged caused to the piston from the butterfly screw was beyond repair. I get it back on Monday, all going
well. I understand Nissan's in-house issues with my situation, but so far this has taken 47 days. Should I be upset, not sure. The guys at
Bathurst have done an excellent job to get this level of repair approved under warranty. Thanks guys. It appears that
Orange was being stuffed around by head office. Thanks guys for trying with your hands tied. I urge everyone to get theirs inspected, or risk a similar situation to what I found myself in.
Should I now be asking for compensation...
