I just recently pulled off the intake on my 01 f250 and noticed that the compressor wheel has small nicks on almost all the fins. It is the stock turbo with 138k on it. There is no shaft play at all as well. My question is what would cause this? There was a small amount of very fine dust in the the take stuck on oil from the CCV. Would surge cause this sort of thing?

Just wondering what the best thing to do is.
Thanks for any advice

 

When you installed the 6637 air filter, did you notice anything?

 

I did not notice anything when I first installed the filter but I did not take a very close look, there may have been some of the smaller nicks but the few larger ones seem somewhat new.

 

That Wheel is Dusted, and I would bet that it's been that way for quite a while. A leaky filter Box w/ irregular filter changes, Cheap Filters.... any of the above....You needs a New one.

 

I would check/replace your filter. Also check your intake pipe to make sure it doesn't have a hole. Then make sure the clamps are tight on reinstallation.

I doubt whatever did that came from inside the engine or you would have more evidence...

 

 

How can anything from within the engine, wipe out or even disrupt the wheel thats inline with the air intake? ..AND, if possible, what other evidence would there be...a loss of blinker fluid

 

Well the good news is from what I've read, pulling the turbo on the super duty is pretty easy, compared to the OBS. I've only done it on an OBS. Worst job I've ever done by far. But, I'd replace this wheel and change your filter.

 

Leak in the filter or ducts let stuff in. Stuff got in the filter/ducts when last working on it. Damaged bits of the ducts broke free; possibly shaved some rubber off when fitting the 6637. Something came up through the CCV.

It doesn't appear dusty so it's unlikely to be a leak, I also can't imagine any chunks of stuff coming from the CCV. My guess would be something got in there when you last had it apart or you damaged the rubber hose when fitting the 6637 and a chunk of rubber did it.
