So, back from the garage and was told that there is excessive carbon build up on the turbo oil feed pipe which means that some how exhaust is leaking from the turbo (shaft?) outside, rather than through the exhaust system. The mechanic is adamant that this means that the exhaust system is clogged and needs to be cleaned/replace parts of it.

 

Does this make sense? DO I need to worry about carbon build up also inside the turbo ?

 

thanks a lot

I would give it a crack with BG244 / BG245, that will clear the carbon out, and shouldnt require any more than about £25 for the cleaner... I anticipate that your mechanic still insists on charging a lot more.

BG244 already tried.  So i would guess it needs some manual cleaning

Also, when I applied the BG244 I could hear the injectors were much louder! is that normal?

yeah as its decarbonising, you would expect a little more noise.

I understand. I dont suppose it would be a good idea to dose again though right? i think I will just take it to the exhaust workshop and have it checked there. Hope I get something. Really fed up because apart from these problems, I really love this Ford  :(

well another tin wont do it any harm, but you have one other alternative that will do your car more good than bad, and may still cost you less than the garage... Terraclean...

that is a shame, perhaps in this circumstance a trip to your mechanic is the best bet, but I would say not before pricing up the new parts that they advised they would clean! if you can get new parts for very little price difference, it may seem overkill but at least its one less thing that will pack up later!

You can get a the oil feed kit for about £100 on eBay and other Ford parts suppliers.

Hi,

One of the possible causes for excessive carbon build up on the turbo oil feed pipe is the excessive where of the injectors washers (one is made of cooper and one of some sort of plastic). This leads to gasses escaping from the cylinder and contaminating the oil which, in turn, leads to the turbine running without lubtication.

I do not think I need to explain how bad this is (you will end up changing your turbine + lubrication system cleanup +  two [mandatory] oil changes).
The louder injector noise, that you've noticed, might be generated in fact by the gasses escaping from the cylinder.

By the way do you also get exhaust gasses in to cabin?
You could check  the turbine shaft status easily by removing the air duct between the air filter and the turbine. Try to move the turbine shaft and if you have any play then you are looking at a turbo rebuild/replace job.

Cheers,

Geos

ffz, Thanks but the oil feed pipe is quite new and dont need to buy a new one. The problem is on the outside where I noticed the carbon buildup not on the inside. Sry for the confusion. 

 

Geos, Thanks for the comments, I have  been suspecting that my injector seals need replacing and had bought a set (actually for the 1.6 HDI but they are the same anyway). was thinking of doing it my self but reading on some forums I found that it would take the average diyer around 2 days work to get them sorted and since there is a lot of removing to get to them I was thinking of giving the job to a professional. Two questions - should I replace the fuel lines when I have the washers replaced? Also is it worth having the injectors cleaned "just in case" ?

 

By the way I had checked the turbine condition and there is a little side to side movement but I think its normal. There is no inside/outside movement. That said I need to make the actuator-movement test. If I find that the turbo needs rebuilding I think I will go for a new one. I found some pretty cheap genuine new ones on ebay for about £400.

 

Thanks a lot

Mad85

Hi,

 

In my case there is no play on turbo shaft. I guess that some play will be acceptable as the shaft normally sets on a oil film. 

1) should I replace the fuel lines when I have the washers replaced?

  No need to.

2) Also is it worth having the injectors cleaned "just in case" ?

Ford does not recommend cleaning the injectors as this might lead to calibration issues. You should have them checked out by a specialist .

 

Cheers,

Thanks a lot. I think I will have my mechanic have a look at the seals and replace them for me. I will also ask him to keep an eye on the injectors and if there is any carbon buildup in there
