Well Happy Turbo whine on 2.4JTD 156 - NOT!

Hi, thought I'd share my experiences (and misconceptions) about a horrid whine I've been suffering from with my '04 2.4JTD 156 Sportwagon for the best (or worst) part of a year. I had thought that the whine I heard from low revs right up through the range was a turbo issue, but the local Alfa specialists eventually identified it as aux timing belt and tensioners, replaced them yesterday, and it's now running like a dream. I've now switched off the radio and am flooring it at every opportunity just to enjoy the grunt.

Thanks again to Ewan at CP Garage Services in Dundee, without whom, owning an Alfa would be a much more painful experience!

Cheers

Iain

turbo whine???

Hi, ive jsut bought a 2000 Alfa Romeo 2.4 JTD. It too has a very odd high pitch noise after about 3000 RPM. The chap i bought it off told me a garage had inspected the turbo and that wasn't making the noise. Was your noise fairly high pitched?

Thanks, Jason

Very high pitched, although started lower down than 3000rpm.

ah that might explain mine also, did it sound like a police siren in the distance and get louder the faster you go? mine comes in about 1750 rpm.

that wasnt the problem on mine, it's now pointing towards the turbo... its got a fair amount of play in it, despite the bloke who sold me the car telling me it definately wasnt the turbo!
