hey guys,
after I start my gts25t from cold it makes a kindof bearing noise whine, (I think) it's not too bad but noticeable. After 5 mins it goes away.
The noise changes with the revs.
I thought it was the gearbox, but it still does it when I push the clutch in.
Also thought it might be the water pump/alternator/a/c/power steering but don't think its that cause it sounds like its coming from the back of the engine.
Any ideas what it could be?
The engine has done 130,000kms, seems in good condition apart from that.
It's standard and was automatic until last year so don't think it has been thrashed.
The fuel pump, afm and water pump have been replaced. (previous owner said)
Can I put a metal rod onto the engine somewhere to "Listen" to the noise to figure out which bearings it could be? Whereabouts would i put it to listen to it?
Is it hard to replace bearings inside the engine? Do they cost a lot?
I'm mechanically minded, done gearbox changes etc but haven't opened up the engine before.
Also do 25t gearboxes cost much for bearings? Can you replace them yourself?
I'm worried if I leave it, it might stuff up the whole engine.
