Help!

[katfish]

hey all. left work tonight, high pitched whine come from somewhere under the car. just had gearbox/transfer case oil replaced before trip.the servo mechanic found what he described as sludgy rubber on the transfer case sump plug, & said to keep an eye on it, what ever that means. only happens when accelerating.

my question is; does anybody know a reputable mechanic that will come to my house to diagnose the problem. I dont want to drive it, as I may cause more damage.

any help would be greatly appreciated. cheers

cheers for reply's, hope this wont cost me a fortune, but deep down, I know it will. anything relating to mechanical work, generally is damn expensive. nissan mechanics charge like wounded bulls least I made it back to brissie

High pitched whine would not be caused by the sump plug, it only holds the oils in.

Most probably a pully has gone .

sure its coming from underneath?

and not from under the bonnet?

looked like rubber mixed with oil on the transfer case plug, gearbox oil was clean, but replaced, transfer case oil was cloudy/dirty, & replaced also. when stationary, revved the engine & no noise. I thought I might have blown the turbo but not sure.

i know a loose fan belt makes a high pitched whining noise thats not loose is it.

i had a dodgy fan belt that made no noise on idle or stationary RPM it only decided to make noise under load. maybe try sparying a $10 can of belt grip on the belts first, thats a cheap one that might fix the problem. hope that helps.

Noise from transfer should only be in 4wd not 2wd possibly somthing else to hard to tell with out looking where r u based may be able to come and check it out .

thanks Flexo; Im at Mt Crosby. good point about transfer case noise in fwd only.

checked fanbelt tension; all good.

thanks Ray, have spoken with him. hopefully, he will be able to diagnose my cars ailment. local mechanic didnt know what was wrong . he said " probly the turbo mate", and with that response I politely bid him farewell.

its looking more like turbo problems, wont know till Friday. if its turbo centre replacement; $1100 bucks+ labour about 4 hours. nissan quoted me @#%$$#$$ 2300 dollars. no way! ouch

Mate black sludge is normal esp if you get a bit of water in the oil, which it sounds like you did. it is usually a combination of crappy oil and metal shavings. the sump plug has a magnet in it to catch any metal deposits floating around in there.

What nissan is it? Does it squeal in neutral with throttle or is it only when driven in gear? you should hear if it is a turbo bearing when in neutral and revving engine. If it's not a loose belt it could be an idler bearing or pulley bearing.

If it is a turbo have a look at what model turbo it is and have a look at e-bay.

I just picked one up for the surf at under $500 delivered from the states. local mob wanted $1800 to swap one. That's not fit a new one just swap over the counter.

Mate,

If it's the turbo that's blown then generally there are more problems than just a whining noise. Because of the way turbocharger operate, if either the compressor or turbine wheel lets go, or the main shaft bends, your engine will fail to generate any boost and possibly blow clouds of dirty oil smoke if the metal fragments have done damage to the inner housing/oil seals.

Perhaps an oil cooling line is blocked, which could create an overheating senario and cause the noise, or an internal bearing is fragged but by the sounds of it, the turbo shouldn't be the issue.

Please don't quote me on this, just my two cents. I'd just be looking elsewhere
