Hey guys my 90 series prado has seemed to of developed a weird 'metally" noise when running mainly just after start up, ive also noticed it seems to be chuggging a larger than normal amount of black smoke when i put my foot down

Any ideas?
Turbo maybe?

Have you tried a bottle of injector cleaner?, with our rubbish diesel its worth doing regularly

[madlux]

usually turbos will only make a noise under boost... need to explain the noise a bit better... something loose?

mine was like a stuffed water pump bearing,but took fan belts off and it was still there, cheers tim

Yea it sounds like a bearing kind of noise, bit like a marble in a tin can but not overly loud , if this makes sense haha

I had an intermitant noise in my prado, turned out to be the fuel return thingee on the fuel pump, replaced and noise went away. Now every now and again I hear a vibration noise caused by the new return valve/spring thingee and the return line vibrates near the fuel tank. Only hear it when the seat is folded forward though.
