2.0 Hdi Oil And Filter Critical

[Rookie2]

Had a car in yesterday (Pug 307 2.0 HDI). the owner reported that his turbo had collapsed (it had), in fact the turbo spindle had snapped.

Now normally this would mean a lot of time and money being spent on investigation and a major clean up of the cars induction pipework/ intercooler/ sump etc etc. The problem was, the owner had spent everything he had on a brand new turbo.

 

So trying to keep his costs down as much as possible I set about trying to repair the car doing as little as possible but as much as necessary.

 

Having stripped the old turbo off I noticed the lack of oil within it, looked at the oil feed pipe and noticed the oil feed banjo bolt was blocked solid with carbon and dried oil.

 

Replaced the banjo and the oil feed pipe and started the engine before connecting the oil feed. There was oil flowing from the banjo. Connected the banjo and started the engine again with the turbo oil return line open, there was no oil returning from the turbo.

 

I then removed the oil filter and replaced it, I immediately got a good flow through the turbo. The oil filter was blocked to such an extent that it would not let oil flow under pressure to the turbo.

I am assuming it was this 6 quid oil filter that caused the catastrophic failure of the turbo.

 

So I guess the answer is to change that oil filter and the oil as often as you can afford, these HDI engines critically depend on the oil and it's quality and cleanliness is paramount.

 

Change your filter chaps, even if you don't change the oil.

Could be on a 2 year 20k mile service interval but that would only be using the correct oil and dealer filter - but most of us would not wait that long to change the oil/filter.
