So I think I am burning oil from the turbo... I am going through about a quart every 600-700 miles. I am not leaking anything on the ground except a few drops here and there. I have checked my blowby while the engine is cold right after start-up, and after being on the freeway for a couple hours. Either way, i have hardly any blowby, a puff every now and then. The only other thing I could think of is maybe the seals in the turbo are shot. It is the stock turbo, never been touched and it has 193,xxx miles on it. The head was rebuilt last summer so I dont think it could be in there. Any ideas? thanks everyone!

Hi Will.It could be very possible that your turbo seals are leaking it past. You can check your turbo inlet, easily. Look for any signs of oil or residue. It should be (obviously) clean and dry. The exhaust-side of the turbine is a bit harder to check, as well as hard to determine. Is there ANY shaft play in the turbocharger?I understand your blow-by is minimal, but it could be a ring sealing issue, as well..

ok. I will pull the hoses off tomorrow and take a looksee. I am also running a AFE cleanable filter so im sure that wont help how it looks inside. I have heard these filters dont do a great job, but I could be wrong. Thanks for the tips and I shall definitely get back as soon as I can on what I find:thumb1:

I pulled that front hose off and everything is filthy inside. It's got to be oil. There is a bit of end play as well. What do you guys think?

endplay is ok, depending how much and in which direction. If you can grab the impeller with your fingers, and wiggle it side to side a little bit, that's normal (provided it isn't contacting the compressor housing).In/out play is another ball game, however.. bottom line is, it's fairly easy to rebuild these things :)As it is also fairly inexpensive.

The only play i could find was side to side. It doesnt have any play in and out so I am good there. It does not contact the housing anywhere that I can see. I am mechanically inclined and have a fairly nice sized tool collection so I am set to rebuild her I think. Where would you suggest getting a rebuild kit? How much longer do you think I could go before rebuilding it? Thanks again so much for the help!! Turbo's are the one thing I didnt learn to much about in tech school:smart:...

Dap has rebuild kits

Since I am going to rebuild it..........Is there any kind of an aftermarket compressor/turbine wheel that I could use? I have seen them for the fords and chev's and they are supposed to be an improvement over stock. If I am going to be in there, might as well upgrade, right?

That would require a rebalance of the shaft and wheel as well as possible machining to the compressor housing From the Galaxy S3

Ok. I would understand the re-balancing. If it were to be a direct replacement, If it were a direct replacement, the machining shouldn't be a problem. Where would I even look for something like this anyway?

Be careful when comparing rebuild kits from various vendors. Make sure of what is included in each of the rebuild kits so you are comparing apples to apples. One vendor I have used is the G-Pop Shop located at: http://gpopshop.com/holset-turbo-rebuild-kits/. This company (as well as many others) offer upgrades, replacements and hybrids depending on what exactly you are looking for from your truck. When looking at changing out to a different turbo you might want to look for something that will fit up to your existing exhaust or you will have some custom work to do. Custom work is not bad, I am just saying if you are thinking about changing the turbo out just be aware of all the issues that come into play when you change something from the stock setup.

That's the one! G-Pop is where I got mine, and I couldn't remember the business name...

I was also going to ask about a turbo hybrid. I dont know much about it, but correct me if I am wrong. You take your stock HY/HX35 and replace the compressor wheel/housing with that of a HX40. Is this common? Would it be worth doing?

Yes, it's common. It does require a re-balance (obviously). Depending on your turbine housing, you may have to step it's size up as well, due to the small cm opening.

Is there anywhere you would recommend finding a hybrid kit to do this? Is there even such a place?

G Pop Shop is one place to look. See my earlier post. Call them and talk to them and they will answer your questions.They can do the work for you, or you can buy a turbo outright or you can buy the parts and do it yourself if you have the know how and tools.

I saw a hybred turbo somewhere, It was one of the good turbo shops, cant remember, Utah IIRC. They had one that was stock but had a bigger exhaust housing and blade IIRC My turbo has got a slite seepage of oil on the back... -------------------------------------------------------------------------------------------------------------------------------------------------------------- '99 quad,long bed,4x4,auto, tow pac,reese 5th ,isspro guages,SMR shift kit, New VP44, JIC fuel line fittings, Red Head Steering/Big D steering brace

Cool, thanks for the suggestions everyone. I shall be looking into it more! I will probably be on again about this at some point but thanks for all the help and everybody's
