terrano 3.0 turbo whistle

[nuffy29]

Hello there i have recently bought a terrano van 3.0 , And seen as it did not start great i have fitted some new heater plugs, not as easy as i thought , after taken the inter cooler of i then had other things to take of just to get to them, not sure what there were one of them stops the engine and i think other is for boost for the turbo i think, after fitting them and putting every thing where it was the it started grand but when i go down the road the turbo now has a whistle ?? I havce taken it back to bits 10 times and i can not see of hear where its coming from ??? Any one any ideas ? I also put a new exhorst on at the same time, do they always whistle ? or is my turbo about to die ??

most likely you have a problem with the hoses/clips inter cooler to turbo/manifold, Rick

Was it a new front down pipe?? Think other members have had issues with turbo noise when they have changed the down pipe.

Money is on the exhaust...

Yup money on exhaust, can you test with old exhaust or too late?

Its to late now ??? It was not the down pipe just the other 3 bits after , the flexi pipe back over

How loud is the whistle bud as I hear a slight whistle from my 3.0, always have.

When I first got the Trol there was a whoosing sound during boost but that turned out to be a loose intercooler pipe - tightened up the clip and that was it.

are they seated correctly?

Thought it was you rustic.

Have they damaged the flexi when changing the rest of the exhaust? Worth a check. If that's now got a split in it that might explain the noise!!

Worth checking although I reckon it would be hard to seat the intercooler pipes incorrectly :nenau and if they're properly clipped on ie. not loose, then they shouldn't make a noise.

I've always taken a slight sound of turbo whistle to be normal on a turbo'ed engine (I quite like it :naughty).

There's plenty pre-2000 6cyl turbo'ed tractors where the owners open the windows when working just so they can hear the whistle (a lot of them fit straight through exhausts so they hear a lot more too :lol :naughty)
