2001 GU 3.0 Patrol - Rattle at Idle

flyboy ,chec k drive blt tesion deviceMine flogged it self to death at 100000 k about 300/400 to renew hope this helps

Input shaft?

With clutch engaged or not? I have had noises from gear box in past vehicle. Next time you get the noise you need a big scredriver against you rear and put the other end on head, block etc. Stethoscope would be better.

Gday,
Direct the post at Handy, If anyone knows about rattly Nissans he would.

Bwhahahaaaaa

Check the serpintine drive belt tensioner, the bushes flog out and you hear aslapping sound at idle, worse in wet weather.

thanks all who responded...A little more on the story...Car was put into Nissan Service last Friday to get the problem looked at, as well as another problem - sluggish, missing at low rpm, poorer fuel consumption, and engine fault indicator light coming on intermittently (I checked for water in filter - nil)
After 3 hours of diagnostics, they tell me they discovered there is air in the fuel line which is causing the engine problem. A new primer pump is required and is on order. Co-incidently, performance has quite worse in the last few days, engine light on more often, but rattle has dissipeared. Could it be something to do with engine problem? Nissan tell me the performance problem is a snowball effect, lack of fuel reaching the engine, computer says more boost please, then the whole thing just goes downhill from there. I'm no mechanic, so i'm a bit oblivious to it all!! is it normal for a service centre to charge for their "Diagnostic Time", 3 hours in this case? Thanks again everyone for your comments.

What the buggers don't tell you is they are only guessing and you're paying for it!!!

My first thaught, having a 3.0 Patrol myself, is ask for a new MAFS, now, regardless of what they say.

MANY MANY, MANY 3.0 patrol owners have had similar problems to yours and most have been a faulty MAFS (mass air flow sensor)
