Can you feed oil in the return? Updated *PICS*
 

My friend wants to know if he can feed oil through the return and have it return from the feed fitting.

I could have sworn i read a post on this a while back that said it cannot be done and seals would be blown yada yada.

I dont want to tell him no for sure so I though't I would would ask since I was unable to find the old post. So whats the verdict, I say no lol

Re:Can you feed oil in the return?
 

hrm good question since gravity takes over.... i dont see why it wouldnt work there isnt a pump inside a turbo so. But please wait for others to disagree lol

Re:Can you feed oil in the return?
 

I'm starting to think that in the other thread the person tried feeding the return line. The problem was actually that the turbo was not roated and he was trying to oppose gravity.

Re:Can you feed oil in the return?
 

what about all those little directional oil journals and things?

?

Re:Can you feed oil in the return?
 

Why would he want to do that? I can't think of how it would work. ???

Re:Can you feed oil in the return?
 

just rotate the center section

Re:Can you feed oil in the return?
 

I'm not positive his reason, I dont think he can turn the center secion or the exhaust housing will be pointing some strange way I'm not sure......

Re:Can you feed oil in the return?
 

then rotate the exh. housing too ;)

Re:Can you feed oil in the return?
 

Re:Can you feed oil in the return?
 

i dont know if i worded myself right b4...leave the exh however it has to be to point right, then sping the center so the oil is right

Re:Can you feed oil in the return?
 

do a search on clocking a turbo and I think you'll get it.

Re:Can you feed oil in the return?
 

isn't the oil feed hole smaller than the drain hole?

Re:Can you feed oil in the return?
 

the drain hole on mine isn't even threaded, you have to add an adapter. So, no.

Re:Can you feed oil in the return?
 

oh man dont make me hook my turbo back up to the oil lines just to see, I wonder what Jeff says about this one.

Re:Can you feed oil in the return?
 

Why would he want to do such a thing? You can do it but it will ---- the turbo, the oil has to go in the designated hole or it will not float the bearings or provide lubrication in the intended manner, wizz, bang, pop, new blower please.

Re:Can you feed oil in the return?
 

no, it can't be done bottom line. if he want' to be difficult, tell him he can switch his coolant lines around ;)

Re:Can you feed oil in the return?
 

All good points, thanks guys.

I'm really not sure his reason I just wanted to be sure in my answer of NO....

Anyways I'll let him know

Re:Can you feed oil in the return?
 

no no no no. the oil drain is big, the feed is small there is no way in hell there would be enough flow through the feed holes to drain the turbo..

Re:Can you feed oil in the return?
 

you can't do it, i think the oil feed has paths inside the center section that go to specific places on the shaft (judging from the cover of my maximum boost) and the drain would just collect it.

Re:Can you feed oil in the return?
 

Well I linked him to this post, this was his question to you guys....

"i cant clock mine... it looks as if the turbine houseing and the center section are all one piece. the odd thing though is that there are bolts holding clampy things down against the 2 just like on the compressor side. however, if you loosed then, only 2 will come out, the other 4 hit the oil and water inlet and outlets...this makes me think well if you cant get them out phisicly, then howd they get them in unless its two diff pieces. however, once loosened, you can look behind the clampy things and all appears to be one smooth piece-the turbine houseing and center section. so i figured maybe its just got crud in there...so i keep em all loose and hit it will a mallet on the out edge a lil...doesnt budge...i try scraping in that area to see if i can find a dip where the 2 would come together..nothing... but what i dont get is if its all one piece, howd garrett get the bolts in? if anyone wants to look up any kind of pics/specs on it, its true name is a tb0363. "

Re:Can you feed oil in the return?
 

i ran into that problem when the whole dam stud came outta my exhaust housing instead of the nut.

ask him i bet the whole stud is coming off with the nut..

if thats the case.. AND the turbo has a PIn on the exhaust housing loosen em off and beat it until you break the pin, if not u can spin it around and get at the other bolts/nuts


make sense?

Re:Can you feed oil in the return?
 

thanks airtronics-he posted this for me. here the thing, i dont see any stud of any sort. the bolts im refering to are actual bolts. little 13mm ones. some ones that are on the compressor side holding it on there tight. but i cant take them all the way out because they hit the oil and water inlet and outlets. they will only come out about half way until they hit. so there must have been a way for the unit to separate for garrett to be able to get the damn things in there. but when i loosen them all and move the clippy things that compress it all toether jsut like on the compressor side, theres nothing there, like no seam where 2 parts would meet. i tried scrapeing at it with a screwdriver to see if maybe it was just covered in ----, but theres no seem that i could find. jsut appears to be all one piece. only thing i can pull off to clock it is the compressor houseing. any ideas or comfromation on this whole 1 piece deal?

Re:Can you feed oil in the return?
 

take pics.

Re:Can you feed oil in the return?
 

you don't have to take the bolts all the way out to rotate the housings. just loosen them. maybe the housing is siezed? to get those bolts out, you have to loosen them, then rotate the housing so they dno't hit, then remove them.

Re:Can you feed oil in the return?
 

i tried just looning them and clcking it, but it wouldnt budge. still looks like its all one piece.

Re:Can you feed oil in the return?
 

get us some friggin pictures i wanna see this 1 piece housing :P

bash it with a hammer see if it cracks loose.

Re:Can you feed oil in the return?
 

im tryin to get some pics, but its kinda hard since theres not much room between the clippy things and the houseing, so the camera has a hrd time seeing in there, but im tryin to upload a few now. i jsut bought a new turbo so it istn of much concern really anymore, but now i have to sell this one, so if it is in fact clockable, it would be easier to sell of course. but anyways give me a few to get some pics...

Re:Can you feed oil in the return?
 

it was hard to get some pics of in there since there wasnt much room at all inbetween there and plus it wouldnt focus good in there as well as flash shadow being a big issue, but heres what i managed to get....

on this one, you see a little line...looks like it might be a seam. well in person, it looks more like a small scratch made into the metal. its only about an inch ling and goes crooked, so i doubt its any kind of seam
http://shownglow.com/z-3.jpg
in thsi pic, it almost looks like theres a seam, but thats not noticeable at all in person... in person its all one smooth piece
http://shownglow.com/z-2.jpg

if you look close you dont see any seam

Re:Can you feed oil in the return? Updated *PICS*
 

your tryin to clock the turbo, right? you're supposed to loosen all 6 bolts, not take them out. the metal piece acts like a lock washer, thats why its wavy. if you turn it hard enough, you can clock it. the compressor housing can be a bit of a bitch at times.

Re:Can you feed oil in the return? Updated *PICS*
 

Give it hell. That is a seam. It's just stuck. Time for a BFH(big ------- hammer). ;)

Re:Can you feed oil in the return? Updated *PICS*
 

liquid wrench.

Re:Can you feed oil in the return? Updated *PICS*
 

Just hit it with a hammer man it will come loose....or just heat it up and then hit it with a hammer has always worked for me ;D

Re:Can you feed oil in the return? Updated *PICS*
 

I had the same trouble clocking mine. I have a t3, very similar to yours. About the 13mm bolts hitting the oil and water outlets, this is a good thing. Just put the sucka in a vice, then use those bolts to separate the compressor housing from the center section. Just loosen them till they hit, then loosen them more, they will back the compressor housing right off. Remember to try to back them off evenly, working your way little by little from each side so you don't break the shaft.

You do have a separate exhaust housing. As Dr. Boost said... it is indeed time for a BFH. After you have the compressor off, put the center in a vice, and nail the exhaust housing till it comes loose.

Re:Can you feed oil in the return? Updated *PICS*
 

I have the same turbo. It is off a volvo 740/760. It was such a bitch to get apart I cant even tell you-- but I drew you a picture that kinda explains it ;D

Bascially, you need a vice, a long pipe, and possibly TWO people! It took me and my brother on the end of a 5' pipe to break it loose. This should help. Oh yeah, where I drew "pipe" (green) the pipe goes in where exhaust would go in...
