Engine noise

Hello,

I swapped my 155 V6 for a 156 2.0 TS a couple of years ago, and now it's done 60k it's beginning to exhibit a few undesireable tendancies. One is a 'diesel' like noise on start-up, which I have heard is due to the 'variator'. What is this, and is it a difficult job to fix?

Thanks,

Brian King.

Re: Engine noise

It is the variator, yes. Same thing was happening to my 2.0TS 147 at the same mileage. Was fixed as part of a 72k service.

The part is around £100 plus whatever your garage will charge per hour to fit it.

As for exactly what it does.......something about low-rev torque, I think, but someone elsewhere on this site will know more!!! Welcome.

Re: Engine noise

Brian, you'll feel better performance once it's fixed. When I got my 147 back from its last service, having had the variator replaced, it pulled so much better low down in the range - acceleration that had slowly disappeared over time was suddenly rediscovered. Great feeling.

Apparently the variator 'adjusts the timing of the inlet camshaft' but I read that somewhere, and don't know what it means

Re: Engine noise

Thanks everyone,

Yes, it is lacking bottom-end pull. I've booked the car in with Jamie Porter to get it fixed.

Best regards,

Brian.

Re: Engine noise

variator is the thingummy that makes the Alfa equivalent of vvti (variable valve timing) work. Fiat/Alfa invented this btw quite a while back, though lots of manufacturers boast about it now.
