Hello there 1st time poster and scared Alfa newbie with what feels like an expensive problem.
Yesterday I was on the M6 when I suddenly lost all turbo pressure, the needle was at zero and I had no power. Luckily i wasn't far from a services so I pulled in. As I dropped to 3rd gear the turbo magically sprang to life again, puzzled, I stopped in the car park and raised the bonnet just to be sure. I gave the throttle a couple of blips and thought I could hear a rattling sound coming from the turbo under throttle but I couldn't be sure.
I switched the engine off for half an hour and then decided to head on my way. As I pulled away on the slip road the turbo seemed to be behaving normally but I could hear a whirring noise coming from the engine. If I had had my radio on and my fan blowing I wouldnt have heard it but as I was listening for something it was quite obvious.
The whirring noise didnt happen at constant speed but every time I accelerated through the gears I could hear this whirring sound.
This afternoon I took the compressor inlet pipe off to have a look at the turbo, there was a small pool of oil inside the lip of the turbo and the spool seems to have a lot of lateral play in it although I couldnt get the vanes to grind against the turbo casing & without a reference I dont know how loose the spindle is supposed to be.
Does anyone have any idea? Am I looking at a new turbo (god forbid) or is there some easy solution to this? Car is a 58 plate 159 jtdm with 40,000 miles on the clock. Apart from the worrying noise the car seems to be running fine.
