Got turbo issues

[Big T]

This is what the compressor wheel looks like on my GM-8. I had the compressor housing off for inspection and decided, what the heck - somebody on TTS might need to see one some day........looks like that day is now :sad:. Your compressor wheel looks like it has been run without an air filter for some time.

On edit; I decided to run out to my shop and snap a pic of my old GM-3 you can see some minor wear on the impeller blade tips - but not too bad for almost 200k miles.
Yes, it's late and yes it's cold (28 degrees)....but that's how we roll here at TTS.
A friend in need is a friend deed!

Anyway you could put his side-by-side with your second pic?

Flat filters are fussy to get to fit right but I ran one for 220k

just some maintenance info:

I change out the air filter when I do an oil change every 3000-3500 miles (depending if the trip is in between change times) Delo 400 with an A/C delco filter. Oil is cheap engines are not!

Fuel filter is every 15K
Transmission is once a year
coolant once a year
Brake fluid once a year
t-case when I do the tansmission
front and rear diffs, once a year
lube points every oil change ( just like goofy lube-sort of)

I agree, the best way I have found was to loosen the snorkle at the turbo and remove it from the box assembly. then change out the filter that way. upon further inspection this evewning, I dont think my box lid /small half is square anymore. looks to be warped a little bit on the top where the three clips are.

I would so like to see you join the A-Team, you are working that truck enough to really see the benefit. All I can say is you won't be sorry. The price isn't any more than you'd have to give for a new stock turbo, plus turbomaster. Of course you could always dink around with a used turbo (a lot of A-Team members have them laying around as doorstops and paperweights), but if there's any way possible to scrounge up the money, you NEED an A-Team turbo.
At least read up on it, there are a couple in-depth threads on here.

But before I spent any money I'd get that oil tested. That turbo is junk, make sure the rest of the motor isn't junk too.

I appreciate it a bunch....... I would definitely say that my compressor is FUBAR'D

Always ran an airfilter since I owned it Fram or wix Hd units with K&N filter spray on them.

Are you saying that you spray a paper filter element with the k&n filter oil?

 

[Veg_Out]

I know right where you can get a turbo!

I've never seen the fins with that kind of wear. Tim is correct, you need an oil analysis.

Any blowby to speak of?

You definitely need a turbo, Where did all of the metal go that came off of the turbo vanes? Bet that motor loved eating that metal over time.

Need to find the cause of tat problem before you replace anything. You will be throwing good money after bad if you don't.

Would love to sell you a turbo, but hate to see one of my babies get sand blasted to death over time,

Yes, it's an old desert racer trick, helps capture the ultra fine stuff that get through the gause.

may of found the problem, I dont think my box is sealing up to well and is letting crap get sucked up in the corners. hard to tell in the pictures but the outside corners dont seam to have the same pressure as the center, couple this with off-raod jouncing it is probably letting the material by.

have my feelers out to local wrecking yards for the 97-up assembly. At least that assemblies air filter is off the floor.

Ya going to use one of this sites vendors for an oil analysis and post it here (be the first time for this with me)

As far as blow by, there is some coming out of the dip stick tube and cdr tube. the original pictures show the cdr tube smoke but hardly visible out the dipstick. what is normal blow by? Also going to do a compression test and leak down this weekend if work permits.

 

[ak diesel driver]

do the blowby test it's here if you search or on Heath's blog on his site

Blow-by test results

Went out and did the blow by test as per Heath diesels blog instructions. It Passes . This make me feel a bit better about the blow-by smoke that I was looking at the other day. So I did a little test. If you take off the intake snorke off the turbo and let it run it'll puff out every orifice (thats what scared the crap out of me. when hooked up to the turbo vacuum, all is good.
Here are some pictures of the test. It pulled the water to a peak of about 10" then settled around 5" above the containers water level.

Hopefully Saturday I'll be able to take off the passenger tire and wheelwell liner, all 8 glow plugs and do a compression test.

 

[ak diesel driver]

Wow!! that's pretty high mine was only about 2" Are you sure your air filter isn't plugged. Or maybe it's the oil your putting on it.

 

[dhjunkie]

Stock un-oiled fram, I'll go out and pull the filter to see if it changes. easy-nuff test.

 

[dhjunkie]

Wow-- good science project. didn't think a fram was that restrictive. just opened the air box and let if free air. the water level droped to about 1 1/4" or a bit above that over the water level of the container.

 

[ak diesel driver]

is it an old filter?

 

[dhjunkie]

new spare for the next oil change. try to get a couple when on sale at local auto parts houses.

puffs more smoke when open air though- still passes the blow by test

 

[ak diesel driver]

Yes that is good you dodged a bullet there.

 

[dhjunkie]

ya, wife is not happy with the sub right now. got to get a k47 air assembly and decide on what turbo to get.
