Turbo Gurus---strange Sound On Warm Up

[Ezz35]

well as se of the newy guys know, my car was written off last week(long strong) and in the market, went to look at one today.

Didnt get to drive it as guy parked it in his building and was parked in by 3 other cars... but when i started it heard a strange whurring sound comming from the turbo while it was cold. kinda of like the sound of a ufo hovering in a tv show(stupid i know lol)

It stopped when i revved it abit but came back when setteled to idle... and once it had warmed up stopped.

I suspect maybe bearings on the way out or shaft play??? any ideas cos im seriously looking at this car and its the only thing holding me back

Hey Dude.

You would need to hear it when the engine and oil is warm.

Mine makes a sort of a whirring sound when everything is cold in the mornings. It goes away as the oil heats up.

I have a GCG high flow.

I don't think it's too much of a problem.

If it's a squeel, it could be bearings, but a whirring could be normal. Take it for a drive, make sure it gets warm.

the fact that it has gotten rather nipply over the past few days would be meaning that the oil is a touch thinker and it takes longer to warm up. my car has started making a bit more noise on start up thanks to minus 5 minimum temps in the morning.

might wanna try a bit ligter oil if its that cold

only just did the oild change, and i wasn't expecting it to be that cold. so it will have to wait cause i can't afford to replace 700km old oil at the moment. i let it warm up before i drive. but that minus 5 degrees is at 5 in the morning, and i don't leave for work till 8.25, but the engine does soak up the cold. i might just have to start parking the car so it get sun from the moment it comes up.
