300 Tdi Rebuild

[Al2O3]

Probably been made into a whole wedge of beer cans by now then!

Looks quite fresh that oil, would expect less if it had had 30k of new turbo to evaporate. Might be a good sign. You going to whack it all back together with new shells and see if any more builds up after cleaning it? Fair old bit of legwork been done over the last few weekends pulling it all apart it seems, fingers crossed this'll be it for a good 150k!

Not sure it would evaporate out of there.
I'm considering having the valve guides changed while the head's off?
Then put it together and run it with the turbo playing in to a catch can

fingers crossed then. I still say get yourself a new vgt turbo

Hopefully, it turns out to be the reconditioned turbo all along. If it is, and I need to replace it, I'll probably stay standard turbo. Though it does sound tempting

It will evaporate and be slowly consumed every-time the engine is off boost, so it should have dried eventually were it not being re-oiled constantly.

Might be worth doing it if you know a good place locally, then you can rest easy on that front. They're not too pricey either really are they?

You can't attach a catch can to the turbo, just too much volume + boost for the cyclonic catch effect to work, you could just drive around with the inlet disconnected for a few hundred miles and see if the oil burning goes. Was that tried before though?

Lastly, getting a VNT/VGT turbo would be truly grand.. and cost about a grand. They really are the best upgrade for drive-ability going - but I'd still be all for trying a recon core again, can't say ive ever known a bad one personally.

Yes, catch can silly suggestion.
Could play it on to the inner wing though. No, didn't try this before
I'd love it if the original oil would have been slowly consumed, but I don't know how? Do you mean it would get passed the diaphragm?

Fourby have a performance turbo core on their website.

I got one, it is nice, spins up quicker and just feels better.

Cheers

It would very slowly be drawn back into the inlet manifold - the stuff that has got underneath the diaphragm would be trapped, though.

You two are a terrible influence

There was nothing underneath the diaphragm.

the difference it makes to economy and drivability is so worth it. No joke but my 200tdi does 38mpg. Bloody good that

 

[Al2O3]

Well, I've stripped the head and taken it to the machine shop to have new valve guides put in.

I know it's unlikely to be the source of the oil, but I thought I might as well get new guides in while the head was off again.
The machine shop thought the head looked ok and didn't show signs of the gasket going. They're going to check it though.

Did you put it in yourself, neilly?

Yep, must say it needed a set big heavy duty screwtype circlip pliers and getting the bolts out that hold it together was a PITA , but is all possible , especially if it has been apart recently.
Needs to be "primed" with a little oil.

Hmmm, you're putting me under pressure
10% more air, is it really noticeable?

 

[windy81]

hahah. This engine will be mint by the end of this thread

Even more pressure. Pack it in, man!

I thought it was going to be mint the last time

You'll be in your element when its working like a swiss watch. Nothing more satisfying IMO

Aye, we'll get there one day

Looking a bit kitchen-tabley that workbench as well. Always the best place to work I find

were you going to worry about the slightly iffy injector nozzles or did they clean up nicely?
