turbo

[woodwizzard]

Am I right in thinking that a 3.1 troop turbo will fit my 2.8 and that they are a better unit to fit?

[Road Hog]

Yes they do fit Jim,not quite a direct replacement,Bumptj has done it,there are pic`s somewhere in here

[woodwizzard]

I thought one or two had fitted them on here. Mine sounds like the bearing is dry so better start looking for a replacement.

[Road Hog]

There is a way that only puts a slight kink in one pipe,will try to get a link/piccy

[Drift]

Yes they fit, though the later turbo's are better.
Its a very easy mod to make fit.

I bet when you turn yours off it sounds like a jet engine winding down

If so dont worry to much, if there is no play in the vains and there are no leaks, though it would be wise to check oil feeds to the turbo for blockages caused by old oil build up, you shouldnt have any problems, some turbo's do make a noise with age but that doesnt mean they are dying.
Mine has made the wind down wine since I bought the 2.8 two years ago, I got in touch with http://www.dieselbob.co.uk/tips.shtml and was assured it was ok via email.
If you are worried its worth 5 minutes to ask.

Remember though Jim 3k oil changes and 6k oil filter and your turbo will love you, even though it wines

Leave it to wind down before turning off after a run, 30 seconds then switch engine off on a normal 30mph run, and if you have just got off a motorway run or high revs give it at least a minute before turning the key off

It was a whine Ste, but now it sounds like a dry bearing noise. I will check the oil feeds though, but with 127k on the clock, that bearing has gone around a time or two.

[Drift]

Check the vains for wobble if they dont then the bearing generally are ok

[alex]

I'm sure mine was 3,1 turbo. just need some fiddling to get it on.

[woodwizzard]

There is no play or wobble, but its sound changed over night so somthing has altered. Why did you change yours Alex?

[Drift]

Are you sure its the turbo, it could be the aux belt tensioner, they sound rough when dry, try oiling it see if it changes

This is the tensioner

[woodwizzard]

It is deffo the turbo, I can hear it through the snorkel now if I stick my ear to it when I switch off

[Drift]

I bet its like mine, just noisy

[woodwizzard]

Thats far too cheap an answer from you, now I'm worried. Going from a whine to a dry noise just don't seem right to me.

[Drift]

Have you checked the oil feeds and changed the oil ?

[woodwizzard]

Oil is less than 1000 miles old as is the filter. I might change it again as it was only tesco's special brew. Not checked feed pipes yet.

[meooo]

I checked inside the inlet/outlet pipes with Jim after Baldhu (when the air filter got wet) and there was very little oil in the pipes, no sign of any water having got through either, but it was definitley whining when he revved up and before switching off.





Sounded just like an old John Deer tractor really................

[woodwizzard]

Thats a compliment............I think

[Drift]

Im inclined to think and air leak or gasket leak possible manifold

[woodwizzard]

If you could see and hear it in the flesh Ste, I'm sure you would say turbo bearing, but if you are sure it is something else I will swop turbos with you

[Road Hog]

Drift`s turbo on run down sounds like a 747 warming up
