Help VW Sharan 1.9 Diesel

[holmbush]

My usually totally reliable workhorse has suddenly thrown a wobbly on me and started dragging all the oil out of the sump and dumping it through the turbo and down the exhaust. Have the mechanics out there a diagnosis for this drastic condition?

[Who me ?]

In the absence of replies ( and sorry -I've no idea) -you could try asking for help on Briskoda.net - Iknow it's a Skoda site ,but (BUT) you'll find VAG master techs on there - and the engine is common to all vehicles .And if you're close to a certain part of the Northants area - you're close to unit 18 - home of decent reasonably priced VAG master techs .

Sounds like the turbo is TF'ed.

Take the inlet pipe off the turbo and check for play in the shaft, should be none. 0.5mm maybe ok, but if i'm right it will be like 4 or 5 mm and you need a turbo.

Thanks Tame technician - turbo was shot but has been replaced with a known good one. Problem persists! Where should I look now?

Did the first knackered turbo coninside with the start of this problem? does sound like the oil seal on the turbo has gone, which can cause almost a vacuum affect sucking the oil out.

How much play in the shaft on the "Known Good" one??



If the new turbo definately is good

Is it definatly sucking the oil out of the sump still, or is it just still smoking lots.

There will be loads of oil in the exhaust and the intercooler from the old turbo failure.

Discovered intercooler full of oil following initial turbo failure. Thoroughly cleaned out and now seems to be OK. Thanks for your help Tame Technician.
