I pulled the AFE off to get to the oil filter easier and looked at the shaft and there are peices missing out of the wheel all the way down the blade. The filter has been always been cleaned out good. Does anyone know whats going on or had this happen to them? Thanks

Do you have a large hole in your filter.

 

Not that I can see. I have some collapsed fins on the filter but that's all.

 

seems to me somthing had to get in to incur that type of damage. I may be wrong but usually from what i've seen a loose or bad bearing always causes damage on the housing and on the ends of the blades. It also looks as if the filter may not have been properly cared for due to the coloration and amount of grit, but could also point to motor or turbo problems, mainly a turbo seal and bearing going out? Yall correct me if im wrong!

 

to me it looks like its right where the air enters or? and not on the sides, where its close to the housing....

if its like that i have a stock charger looking like that... just not as much....
that one has now been replaced by a new HTB2 64/14 also

 

Maybe somebody threw a beer at it!

 

awful dirty in there.... what brand filter?


chewed on something pretty hard to do that type of damage

 

As an aircraft mechanic, I've seen some inlet damage from a number of things on turbine engines. From what I see here, it looks like something large bounced around a couple of times before being ingested. This damage does not appear to be from anything that got through your filter. If something large did go through there, there's a good chance it may be in your intercooler. I'm just shootin' another angle based on a pic here...

 

im kinda on that boat too! Somthing went in there, Is there any chance of that the damage to the filter is worse on the inside? I just dont see plastic parts causing damage that severe! i have to agree , seems like a golf ball bounced around in there....

 

I had an HX-50 shell but I thoroughly cleaned it and there was nothing on the inside as far as the eye could see. HTT said $130 gets a new wheel installed so I might go that route and get a new AFE as well just in case the one I have is letting stuff through. Thanks for all the replys guys.

you got an exhaust leak? The compressor wheel looks like its full of soot.Id get the turbo off ASAP,and return it for repair.

 

Any chance of ice damage?

I bet it’s from when you shelled the hx-50; it did the same thing to your hx-35 when you put it back on after the hx-50. There still has to be metal shards in there.

 

Sorry for you....
I took the picture in to my engine department (military), and we concurred on the same cause, normally what we in aviation call FOD (Foreign Object Damage). Something upstream entered the system, bounced of the faces of all the blades turning at a high rate of speed until the object, broken into small enough pieces, entered into the turbo. We see this quite often during extended phase maintenance where we disassemble the turbines due to degraded performance. In our case, we can actually file a number of the blades to "blend" out the imperfections, with minimal out of balance effect.
I would suggest, especially if this has happened before, disassembling your entire intake system and looking for the opening that is allowing external material into what should be a closed system.

 

Not to sound like a broken record but it looks like you re-routed your exhaust through your turbo's inlet.

I agree with the foreign object bouncing around in there before ingestion by the turbo.
