Hi FF,

I recently aquired a Stilo, which i very much like, though I i have some questions about it i couldn't find anywhere.
My Stilo is the 3 door facelift Racing version with the 8 valve JTD rated at 88kw. The car has 180000km on the dash. Ever since i got it has been making a strange rattle when upshifting... In all gears, most obvious when changing above 2000-2500 revs. At first i thought beeing the racing version it may have some king of stock blow-off installed ( like in some seat models) but then i am not sure, and i haven't got the time to check it with my local garage.

After some digging i found some posts reffering to wastegate rattling, what do you think? Is this a serious issue? Or might it be something else?

Another question i have is about the cambelt, i know it has been changed at 100000km, and now the current belt would have 80000km, should I go about changing it? Or 100k is a normal interval?

Greetings from Spain,
Dan.

80,000 is the limit for a cambelt in my opinion so change it as soon as you can.

Where does the rattle seem to be coming from, under the car, the engine ?

I can hear the rattle clearly when I'm driving, if i sit in the passenger seat ( right side ) i can still hear it, but barely. I tried to localize the sound and it seems to be comming from under the steering wheel.
The belt olny has about 3 years of life, and the first time it was changed was in warranty, i was thinking on changing it in about a month or two.

Loose heat shield will make a tinny sort of rattle whenchanging gear or a loose baffle in the exhaust.

The JTD main gearbox mounting was known to rattle. It was modified several years ago to prevent the rattle.

Thanks for the hints. Though it seems to me it has something to do with the boost and the turbo, for example i tried while in fourth engaging the clutch and reving slightly, when i would lift the foot of the gas the same rattle would happen. Again if i would shift below 1900 rpm nothing happens, also if i do a powershift ( changing the gear without completely lifting the gas) nothing happens.

Sounds to me like the bottom engine pulley needs replacing, they rattle sometimes, difficult to pin point unless your looking for it.

Hello again guys,

I did some more listening and the rattle seems to be echoing down the exhaust... Any ideeas what might be the cause?
Thanks.
