Thanks TJ.

Any reason why I shouldn't consider a rebuild kit instead?

Instead of a rebuilt turbo? Yes if you have a thrust bearing failure (wheel slides back and forth in line with the shaft) the turbo may not be salvagable.

here are pics of my turbo after a thrust bearing failure. It would have cost me more money to repair mine rather than buy one from Ron

I guess I will be checking out the turbo tomorrow. It's still odd to me that stops making racket after above 1000 rpm.

Thanks. Post or PM a few details about the turbo. I will start assessing things later this afternoon and I should know by tonite whether or not the turbo is the culprit.

To All:

Thanks for all of the replies. I have received a lot of good info and I feel much better about my chances of handling this job myself. I will continue to post as I work throughthis problem so that hopefully it will be a useful thread that helps someone else in the future.

Ebay has several used turbos right now for 150 and 100 dollars. If you just want something to get you by one of them might just work for you. You pay that for a used one and rebuild one of them while you can still drive.

Yes, I will be shopping tonite and looking for just those kinds of deals. I need to be careful though, dont want to buy one that will detonate and take the engine with it.

I just removed the intake tubing. Here is a shot of the turbo.

There is no play when I push and pull the impeller - There is a slight bit when try to move it side to side.

Yep it all sounds exactly the way it should be. Is the intake housing on your turbo black? it looks like it has been painted which would lead me to believe it has been replaced once. Intake wheel looks like it in great shape too. Turbo is not your problem.

Are you sure that EBPV is unhooked?

Turbo came as part of a Ford crate engine. Previous owner had it installed about 85K miles ago.

I need to make sure that I unhook the correct connector. Tell me again where it is.

Next I will start it up again and see what happens.

Is this the connector (arrow, middle of pic)? It sits right under the turbo.

Question 2: If unplugging it doesnt work, what is my next step?

Yes that is the connector. is that the one you already unplugged and the noise was still there? if so still leave it unplugged until we get this figured out. Also it could be the valve is stuck part way closed or something weird like that.

Yes, that is the connector I had undone before.

Something new...I unplugged the ebpv connector again. I turned on the ignition waited about twenty seconds after the glow plug indicator shut off and tried to start it.

No go. It turned over but did not start. I quit trying after 20 seconds or so.

And now there is weird looking smoke from the tailpipe.



Smoke coming too from around the passenger side exhaust manifold.
