[fishnsurf]

i metal banging noise is coming from the area of the sump i think closer to the back of sump (not so sure) when engine running either in neutral, park or drive it just started this afternoon and is very loud from under the patrol and whilst standing next to it, not so loud under bonnet, no warning lights, oil level ok, i run penrite SIN O 0w-50 full syn and have done for the last 4000ks, i let the patrol cool for couple of hours and noise still there on start up at idle... , 130000km any ideas would be great dont feel i should drive it as is

Have you dented sump or ran over/into anything recently

[Yendor]

There have been a few reported cases of flex plates cracking.

[fishnsurf]

[fishnsurf]

This might not be your problem.

[fishnsurf]

thx yendor i was just reading that thread ... any other ideas? its strange that the noise just started from nothing to quite loud

[fishnsurf]

i have towed i trailer,boat or caravan nearly everyday of the 2005 patrols life this would prob put extra pressure on the flex plate i am guessing

[nissannewby]

I have heard of the bolts failing too. Maybe one bolt has failed and is being bounced around in there.

[fishnsurf]

Update .... Had 2 mech listen to patrol today both are unsure but between us dicided to check starter motor which was all good and then through an access port checked the bolts that hold the touque converter to the flex plate which all seem good so from here it was suggested to unbolt the touque converter start the motor and see if noise is still there confirming weather the problem is forward of the touque converter or not ...... The noise now is like if u put a bolt into a can and shake it hard then when motor turned off its like the bolt rattles to the bottom... Note i am not driving it just starting it in drive way..... If anyone has had similar problems would be great to here.. Thx (maybe a bolt has dropped out of converter its self)?

[Yendor]

Have you tried hitting the exhaust system?, maybe it has something loose inside it.

[MEGOMONSTER]

I had a tinging noise from under me and the shop that fitted the exhaust, when I took it back to him, couldn't find the noise, I told him the noise had to come from the muffler. Well I found the problem the exhaust came out of the rubber supports. Put it back in and secured it. Well what do you know, no noise. Proud of myself. Wohoooo


Jack taps here...........

[fishnsurf]

Thx ...Exhaust all good Noise deffinately from the rear of the sump ... I have been under patrol whilst it is running with mech

[nissannewby]

Sounds like its time to take the sump off and have a good look.

[timbar]

Could be a journal nut off a con rod floating around ????

Possible loose sump baffel ?.

[fishnsurf]

[kiwijase]

Good luck with it.

The lack of metal sounds like a good sign.

Any chance of a photo of your trans temp sender while you're under there.
As per this thread http://www.nissanpatrol.com.au/forums/showthread.php?9725-Automatic-Temperture-Sender&

[fishnsurf]

Well it ended up being a loose bolt in the transmission have not been givin exact details yet just pics its one of a few that holds the touque convertor in place I pretty sure .. It worked its way out and was banging as it spun ...

Sounds like one of the drive plate bolts. Hopefully it hasn't done any damage to the torque converter or the back of the engine block.

Thanks. So the bolt they drill is the banjo bolt?

I want to use a micro processor and LCD screen to display the temp, I just need to see how/where they mount the sender unit.

[kiwijase]

good to hear it was a minor prob

[Robo]

No real damage done?
Use a little locktite and replace the bolt?.

[threedogs]

Got to be happy with that, X2 with above remove all and re do the lot with locktite.
.

[fishnsurf]

it was a transmission out flex plate off then there were 4 10mm bolts holding like a cover plate or something on ... but yeah all bolts replaced with lock tite cost $741 includes a rear seal kit..... but as always i seem to be a bit disappointed with people not putting things back as they found them and checking there job before receiving the cash ............. they missed 1 bolt to hold a pipe in place there was 1 metal tube that they forgot to reconnect back to a rubber hose and the in and out fitting for the trans fluid are both leaking obviously they used the same copper washers... what do u do

[threedogs]

You take it back and politely explain what they have missed but were prepared to take your money.
this may be the case of the young fella doing the job and the so called Master {loose term} not checking the work correctly
SHITE tell them your nor happy, as you're not happy are you??

[lorrieandjas]

Nothing more annoying than spending good coin on a repair, only to have to repair the repair! It's a shame you hear it so often....

[the ferret]

Hook it back and stand there while they fix it!!
Nothing wrong with the dollars you gave them so there should be nothing wrong with the job, end of story.
Cheers, the ferret.

[Robo]

1/2 a job done.
Full payment.
Potential damage done as a result.
I'm with Ferret, they fix it at their cost this time.
And the standing there is not such a bad idea.
Some people need supervision.
To simply guilt em into doing the right thing.

yer get the apprentice to do the job and charge for a fully qualified person to do the job
