Reply With QuoteI know when the intercooler hose pops off you loose all power. Can't help on the turbo as when mine went it went with the engine so was steam, oil, smoke from bonnet and nothing out the back plus every light the dash could find lit up.
Driving my TD5 for a km or two with slight noise (like turbo unhappy) then lost all except about 5 horsepower with a thick cloud of smoke out back. So much smoke driving a few hundred metres home I couldn't see anything at all behind. Very embarassing - eco savage. Under the bonnet there is oil sloshed around the turbo.
What surprises me, noting my total inexperience with turbo failures, is how much horsepower went - it's like running on one cylinder. No dash warning lights lit up. I'd have expected to keep running, without turbocharge, at at least 50-60 horsepower.
Hope it is 'only' the turbo. It's b..... cold outside but I'll have to take a closer look/pull it down. What a weekend!

Sounds like you lost plenty in the end there George but I assume you had experience with just the hose popping off too.
I've got mine appart now and yeah, bearings are shot, shaft through cartidge has sheared and oil 's everywhere - less in the upstream exhaust manifold happily and I'd ditched the pollusion rebreather earlier thank goodness. Impellers (or fans?) look the worse for wear so I suppose that means a new one to be sourced.
Number is hard to read, looks like 4522_9-6 and I've heard the underscore (missing number) should be a 3.

Sourced a new fully balanced rotating assembly for the turbo from www.turborebuild.co.uk for less than $620 delivered - pretty happy with that. Goes well and easy to assemble.

Hi,
Do you remember the part number?
Cheers,
Andy
More a description agreed with supplier, i.e. "The CHRA - centre housing & rotating assembly - i.e. the balanced centre housing and rotating assembly with plate, to attach compressor turbine housing without dismantling the CHRA on the one end, and without the heavy cast turbine housing on the other end. See photo called 'CHRA' for CHRA. Other GT2052S turbocharger pieces not supplied (wastegate contoller, compressor housing & turbine housing) can be seen in photo called 'turbo_less_CHRA'.
