1HD-T turbo troubles - What do I do?

So my turbo was rebuilt and it is being shipped.
It eneded up costing about $567 with tax (excluding shipping both ways.)

It looks like by the time I am done with gaskets labour and shipping and purging the fuel system it will be around $1000. Not cheap, but I am not going to complain.
All and all I consider the "low price" a blessing. :)

But here is the question: When ADP rebuilt the turbo I asked about the piece of metal that jammed in. They did not think it was from the turbo. Question is, where did it come from?

It was to big to go through a valve, and my engine did NOT make any funny noises, and still runs great. Nor is it head gasket material. So where could the piece of come from? Maybe an extra piece from the casting process in the exhaust manifold?

I don't really want to risk having another turbo go until I know where it came from.

Any ideas?

Thanks,
Nick

Whats the piece made of? Carbon? was it stuck in the hot side or the cold side of the turbo?

If it was carbon you might want to look into it more. Its previous life could have idled all day long somewhere. Idling can cause stalgmites of carbon on the valves. Possible with the canadian driving you are doing it is working free.

If you are doing the work yourself maybe prior to the install, plug all the oil lines and coolant lines(if any) and do a diesel purge thru the engine and run it with out the turbo installed. Give it a blast at idle see if any crap flyouts after the purge.

When I did the purge on my Mercedes the crap that came out the injection pump was awful. And driving all kinds of crud came out.

If the 1hd-t has the return line to the tank, you hook up and loop thru a jug containing the purge. It takes about 15mins to get the two can thru. Then change the filters.

That may make you fell better short of pulling the head to look.

Are you installing the turbo yourself?
 
Hello Brownbear,

I am not doing the work. A friend of mine is. He is a diesel mechanic.
I took it to him to purge the fuel system. Then he ended up pulling the turbo.
So I will have him put it back in.

The piece it self was made of metal. It was probably about 1.5 inches long and .5 wide. And partly folded from jaming inside the turbo. The piece also did not taper, it was pretty much a solid .5 inch. Thickness was between 1/16 to 1/32.

Any ideas? I have none.
My only thought is it HAD TO be inside the tubro somewhere in some seal. There is no where else it could of come from.

Cheers,
Nick
 
Can you take some close-ups of the piece with good lighting?

It is rather an important question, isn't it?

Maybe you should hang it from your mirror until you find out. Expensive piece of metal.

It is a very expensive piece of metal.
I no longer have the piece of metal in question.
I shipped it to Vancouver with the turbo.

As I understand it, you do not even need a down payment now, 0 down and CMHC financing.

Yah but then you pay the CMHC charge. Which if it can be avoided is best. Also CMHC has stupid rules. If I can avoid using them I would. The purpose of them is to "GET" into a house. I think I paid 6k to them on my condo in Calgary when I bought it. UUUCK


Ask the turbo shop what they think it is. If they still have it you should send it out for analysis. Might be better to know the material.

Then we can ask lots of questions to some guys who rebuild them to see what it could be.

Engines are funny, sometimes they suck things in and spit it right out. With out damaging anything.

what work did you do to the engine before this happened? Could it be part of a gasket from the fuel nozzles etc...... Something fell into the cylinder when it was apart. If you had glow plugs I would say the tip. Maybe time also for a compression test to see if some of the valve came apart.

It could be a foreign object that went thru the engine, if thats the case it should not happen again. fingers crossed.
 
Yeah, engines are funny sometimes.
I think I will just make darn sure nothing is loose in there (allthough I think I am good).

I did run the engine for a while with the turbo plugged and nothing new came out, so I feel pretty confidednt that nothing else in in there.

Right now I am still thinking it was inside the turbo somewhere.
There is simply no where else it could come from.
And the engine did probably run 1 hour after the turbo was siezed (moving it from place to place) and nothing else came out.

As far as recent work I had not done anything. Last thing I did was the rear brake pads about 2 months before.

I am guesing the heat generated on my trip loosened something up that had been in the truck for many years. Right now that is my best guess. As the truck made no funny noises or anything. The turbo ran fine until it was shut off. After that it had the issue of an IMEDIATE jam.

I am guessing: Where ever the metal came from it has always been in the turbo. Working the turbo hard (pressure and heat) loosened the piece off. Once it came loose the pressure in the turbo held it in place. Once the tubro shut off it gently feel in a jammed. Next time I started the truck it jamed, thus the no noise.

Had it come loose while running it would of gone flying into a running turbo and would of heard it. And I did not hear anything no my passenger, and we were not listening to music at the time we were talking.

Anyways, that is my best guess and there is nowhere else for it to come from.
Unless there is some type of interal sleeve or round bushing between the turbo and manifold.

Cheers,
Nick

Turbo is already rebuilt and back in the truck.
99% sure the piece came from the turbo.

But I don't remember hearing anything when I did shake it.

Well anycase I'm so happy that you are back in your cruiser again .. !
 
Did you say the piece was lodged in the cold side of the turbine? Any chance some previous owner had one of those "Hiclone" bent up pinwheel pieces of sheetmetal in the intake at some point in the past? I couldn't see that hunk of metal going past the valves without major drama, so perhaps it was in the intake somewhere and luckily dropped into the cold side while the engine was not running and then jammed it. Obviously with the $600 rebuild your housings and wheels did not get damaged.
 
Have you got metal gaskets on the exhaust manifold. The bit the jammed my turbo was off the gasket, a blow had burnt a piece off and it got sucked in (don't know how as it should have blown it out not in. but there you go). I only know this cos I found the piece of material and it matched up to damage on the gasket.

Metal gaskets were good too. No missing pieces.
Final verdict was a piece left in the manifold from the casting.
