Turbo Oil Line Nuts... WTF!?

[AjWit]

I just spent the last 2 weeks doing a HG job by myself, out on the street in front of my house. I finish it(i think) and attempt to start it for the first time, on the second turn of the car she starts and i feel better already, then i look at my gauges and my oil pressure is around ZERO, i instruct my friend standing next to the car to look under neath and he confirms my suspicsion, oil leaking all over the place. I immeadiately turn off the car, my oil filter is soaked so i assume thats what it was, replace it, add more oil, start... oil leak still, damnit.

I put more oil in, start the car, and quickly jump out and get underneath the car while it's on jackstands(i do NOT reccomend this), i look up at the oil filter and turbo, and its leaking from the oil line where it connects to the turbo. I remembered that when i installed it(i left the oil line connected to the block upon removal of turbo), that i could NOT get any torque, or even a ratchet on it to tighten it down properly on the nut closer the the engine.

Just spent the last two hours, on my back, now covered in oil, and i CANNOT get to that nut to tighten it. The one closer to the fender is good, but like mentioned i cannot get the nut closer to the engine(but on the turbo end of the line obviously). I have used a standard socket to get it started but now the stud is protruding far enough that the socket wont bite anymore, and a deep wall socket will not fit up there due to a thinner metal oil line being in the way, a wrench has already been ruled out as well. My BHG has been fixed and my car runs, please give me a good suggestion to fix this oil leak and make my car road worthy. Thank you very much for reading and helping.

Any suggestions?

Unscrew the line off the block, pull the turbo off and torque it properly where you can get to it, then put it all back in and you just have to put that banjo bolt back in the block

I'm with this guy ^. That seems like the only other way to do it.

Well, if i cant find any other valid suggestion it looks like i will have to. To be clear on this, you are saying to unbolt turbo from downpipe(i dont have a heavy elbow anymore), then unbolt it from the manifold, disconnect the turbo to IC pipe, and then remove the banjo bolt from the block side of the oil line?

That stud can strip also, so be careful. You might be turning and turning and getting to no results.

I've been cautious to that, ive only put the nut on and spun it maybe 4 rotations, i can't even get it to the point of resistance yet, when i did manage to get a socket/ratchet on it, i have to use my other hand to click the ratchet back, that nut isn't even touching the flange yet i dont think, i think its just sitting on the stud, doing nothing. I'm going to go back outside and get more oil on myself, maybe throw some not nice words into the air and try once again, or wait until my roommate gets home and have him take a crack at it, sometimes another person looking at the same dilemna can find a different appraoch to it, we do that on each others cars all the time, he has a base model 5 speed 3000gt.

I also had trouble with this, gotta pull the turbo, only way. You will just get more and more frustrated.

OK guys hear me out on this, i just used a couple friends of mine to help hold the extensions upon extensions that i had together, i found a small ratchet and i got it torqued a bit, started her up and no more pouring oil onto the street. Now, i still have the same other problem as before, no oil pressure on my stock gauge. This has me worried, i do NOT want to risk frying this engine after i just rebuilt everything and put a new head on it. Do you think its just a wiring problem or should i maybe replace the oil pump now? for the record, i have no money to help myself with, i hate my life, work my ass off to pay bills and yet have no money left...

Anyways, no oil pressure as stated by my stock oil gauge, ideas?

I take the turbo off as one assembly. Take a 17MM and take off the oil feed line from the block. ( 2 ) 12mm bolts that go to the block for the oil drain. the coolant liens can be disconnected with the clamps that are on it.

4 downpipes bolts, 4 exhaust manifold to turbo bolts, and inter cooler pipe, bam it's off.

I have sometimes taken the two 10mm bolts from the oil feed/return from the turbo off, but it's a pain in the ass to really get the turbo to line up correctly.

You just need some different tools, and you can do it without pulling the turbo. Try something like this:

Either you ran it too long spewing oil, or maybe you just left the wiring off of the sender. These cars run with very low pressure at idle. Is it showing any at all, or just plain dead.

No it is not budging at all, i do mean ZERO oil pressure, i know usually when i start up it'll be at like 20 or so, mid way below 40 and above 0. Now i have nothing on the gauge. I made sure the oil level was good before every start up, i had a gallon jug that i ended up using all of. I'll have to see if my haynes manual has anything about the wiring on the sender to see if thats the problem, but i haven't found anything in it yet. Does anybody know where it is and could briefly tell me? I still have the car on jack stands.

i bet its the pressure sender connector. its next to the exhaust manifold behind the water neck

Put an oil pressure gauge on the block itself to see if your pressure is good. I would do that first and then go from there.

Well, since you said you have oil spewing out from the turbo, it's getting there somehow. Oil won't just flow uphill by itself, ya know. (I'm betting your oil pressure is fine)

And I've gotten those nuts screwed down a few times with the turbo on the car. I used Crow's Feet on a long extension. Worked great. If I remember correctly, I ground down one of the Crow's Feet a bit, though.

a better description would be right behind the power steering pump... :sarcasm:

its a rubber covered bulge with a wire coming out of it.

 

[kotu100]

u can actually get to this bolt for the underside of the car if you have a bunch of 1/4" ratchet extensions, and a swivel.
it is a lot easier to just take it off though.

 

[nosman4]

The oil pressure sender is right near the oil feed line for the turbo, (where it comes off the block). I would check to see that it is plugged in. If it is, you can try grounding that wire and your gauge should max out. Don't leave it grounded for too long, it can mess with the calibration of the gauge. If it doesn't then your gauge is bad or there is a break in the wiring somewhere. If it does then there is something wrong with the sender. As stated before it is likely that you have oil pressure due to the oil spewing everywhere.

 

[jimi87-t]

I've put on and taken off the nuts many times now and have never had this much of a problem. I just use 1/4 sockets and extensions :dunno: Maybe I'm a contortionist and didn't know it...

But I think everyone is missing the obvious here,
If you didn't find out that there is no oil PSI and there is oil spewing all over until after starting the car....
This means you did not prime the oiling system before starting.
If you would have went through the priming process, like you are suppose to, you would have noticed no PSI and an oil leak before ever starting the car, and now this means possible damage to the turbo and/or to the engine bearings....
Short cuts FTW!

I swapped turbo's due to the fact that the last one blew up(seals i think), slapped on another ct-26, reconnected the oil pressure sender wire, oil gauge has returned(thank you), oil leak is now gone.

My new turbo does this though, at 2lbs of boost or higher it spits white smoke out the tailpipe. Only during boost does this happen, oil in IC and piping or maybe bad seals on this one too?
