SERIOUS loss of power ???


 Guys,

  I have just kicked my exy for the second time (first was after getting bogged on Stockton Beach) and I need your help.

  The exy has developed a SERIOUS loss of power and I am a little concerned.

Symptons:

 1. Travelling at 110kph, exy feels like it is studdering every 5 or so seconds.
 2. Any slight hill, the exy slows down dramatically and can't get up in 4th of 5th gear. One hill I had to drive up in 3rd at 60kph.
 3. Exhaust is spluttering and making a popping sound when stationary.
 4. From a stop start, the exy sounds like a tractor, stutters and has no power at all until I get to about 50kph.
 5. Engine bay is EXTREMELY hot.

 However, the engine revs are normal for the speed and gears selected. Contact the NRMA(No Real Mechanic Available) and he told me it appeared electrical and he couldn't help me.

 Any advise before I contact my dodgy Nissan dealer and ask for their help. Exy has done 60,000 trouble-free ks up to this point.

 Update:
   After kicking the xtrail again, I took the spark plugs out and discovered that plug 1's electrode was totally bent closed. Any advice ..PLEASE !!!

Brett,

If I were you I wouldn't be driving your exy anywhere as you may do further damage.

Sounds like you might even have some sort of serious mechanical problem in cyclinder one. Something must have have bent the spark plug electrode, and I'd bet it's stuck inside cyclinder one. Your probably running on three cyclinders?

Mate organise a tow truck and get your exy to your nissan dealer or regular mechanic for a check over.

Brett,
 Did you fit your spark plugs the reason I ask is that if someone else did they may have fitted it with out checking the gap and just assumed the gap was correct or they dropped it.

Brett,
Just another thought did you attempt to tighten the butterfly screws when you fitted the TBS as they would have been loctited in and when you tighten something that has been fitted with loctite you have effectivly broken the seal and you should remove buff and refit with stud lock or similar .Just putting the info out ther for you

Hi Brett,

Sorry to hear about your problems with the exy.

I don't think it is the butterfly screws and you wouldn't have been able to see them when fitting the TBS anyway. To get to the intake butterfly screws the top cover of the intake needs to be fully removed. The screws for the butterfly don't come lictited at all, hence the reason for the recall overseas to open the intake and have them loctited, but this is not the issue in your case I hope.

We have already seen dropped plugs by the dealer with Jamie (I think) and the case with your damaged plug sounds similar.

Have you had your exy serviced recently (at a dealer or elsewhere)?

No, unfortunately it's not a dropped plug. I do my own plugs. Looking closely at the electrode side of the plug, the base of the plug is all pitted and damaged. I'm guessing something has come loose and got between the piston and plug, probably the butterfly screw. I have not touched the butterfly screws.

Speaking to Nissan, when they asked if it was still in warranty and I told them "No, of course not.", there was a deafly silence and then a "mmmm, gonna cost a bit, sorry." Early guestimates vary from $1000 to 'several more' if the damage is more severe to the upper head. Fingers crossed, but I have a sick feeling that it is not going to be good news.

Anyone else experienced this...
Can anyone lend me a balaclava and the blue prints to a local bank...

Brett,

If it is indeed the butterfly screws, then you have the official statement from Nissan Australia to wave in front of your dealer's face and get it done under Nissan warranty with no charge to you at all. (refer to the butterfly screws recall thread for this)

Brett. While it doesn't sound good, I can remind you that others have had stuff repaired "under warranty" after the warranty has run out as it was found that it was no fault of the owner of the vehicle (ie: internal engine parts coming loose, as what it appears to be in your case).

For it to be something other than the butterfly screws, it needs to come from outside the engine, meaning it has to pass through the filter, through the throttle butterfly, through the small pipes within the air intake manifold, through the butterfly (which I'm assuming is the one that adjusts the variable length intake; where others have had the screws come loose). For something foreign to get in there, it's got to go through an obstacle course to reach the combustion chambers.

Unfortunately you might be the next person to experience the "butterfly screw" phenomenon, but like I said at the start, I would expect Nissan to still repair this fault at their cost as it's something that has already been indicated as a manufacturing fault and can be caused by no fault of your own (regardless of what "options" you have fitted external to the engine such as exhaust and TBS).

Or have I just shot myself in the foot and got the "butterfly" issue confused with the "disintegrating exhaust pieces entering combustion chamber" issue?
