Emergency!!@$%@

[VadersV6]

I had a leak that progressively got worse, and this morning was bad enough to be squirting oil all over the front of my motor. The oil feed line to the turbo was the culprit. I took the elbow off, cleaned it out, and put some blue loctite on the threads and screwed it back in. When I screwed the feed into the elbow, the threads stripped, and I didnt even get to torquing the damn thing yet. They must have already been shady. I did everything I could to salvage it. Even though Ive got a whole machine shop, and i have a million taps, I didnt have this thread..its weird, like a 1/2-28. I dont have the tooling to machine a new one in the lathe, so I was hosed. I tried everything to seal it up, but nothing works. I had to drive it home with smoke coming out of the hood and stinking to high heaven. oil is everywhere.
So is this elbow some back order special part that I cant get for a month, or is there some brake section of an auto parts store that would have something like this? Given the offset oil channel in the thing, and the tapered seat to seal the line, I doubt it. Autozone cant even get me a set of intake gaskets, let alone something like this.
What do I do?

A lot of guys have them laying around. I will see if I have more than one. I know I have one, but may need it due to my oiling problems if I bypass the DIY turbo saver... I will try to find one!

 

[VadersV6]

I appreciate you looking, but I need something tomorrow..like tomorrow morning. This is my daily driver and I wont be able to get to work, unless my mother in law loans me one of her cars. I guess you should still look for it and mail it out if you find one, and Ill send you a check...in case the other options fall through. I know someone literally across the street who would probably have one, but I try to avoid psychological abuse if i can help it.

 

[Squid4life]

Gotcha, know exactly what you mean on all points... I will see what I can come up with.

 

[Squid4life]

Too bad we weren't in July of '06, I may have been local, could swing one over. I will be moving to San Diego area in July. You far from there? Feel free to PM if you don't want to post location here.

Isn't it NPT?

 

[Blown&Injected]

Please do not take offense to this:
But with all that machine experience and you do not know what pipe threads are?

Go to the hardware store and get an 1/8 - 27 NPT tap. I know the hole is much bigger than 1/8" but NPT sizes are strange and are not the same as the corresponding opening. It is going to be a trick to keep the chips from getting into the turbo. If the threads are messed up, you will need to crank the tap down deep so the tap will be extending into the center section.

It is easy to make a -4 line to feed the turbo.

 

[salvageV6]

Isn't the oil feed line to the turbo 1/4" flared pipe?

I believe those threads are straight not tapered.

Should be NPT from the adapter brass block into the engine block.

And it's NPT for the oil pressure sensor fitting.

Perhaps quickly you could get a I believe it's 1/4" NPT pipe to 1/4" flared pipe adapter right angle fitting and leave off the oil pressure sensor/switch temporarily.

Something similar to whats up top on the turbo in right angle only the larger NPT size into the block. Or just get a 1/8" one like on the turbo and use an NPT bushing to increase the size that fits the block.

Feed line bends easily enough if you use proper care and don't crimp it shut.

Assuming the threads are totally messed up on the existing adapter.

Is it like this
http://www.smithfast.com/ifme.htm

auto parts should have it maybe you have a napa near by ?

If you cant find it i have some at work (La airport) let me know.

 

[salvageV6]

I assumed it was the lower block fitting the feed line went into that was the problem.

The upper elbow adapter at the turbo is 1/8" NPT male to 1/4" flared pipe right angle, and most, if not all, NAPA or good auto parts stores should have that fitting most likely in the bins on the floor or just behind the counter.

Looking for it will be quicker than asking for it.

 

[salvageV6]

402X4 1/4 1/8 .188 .177 .92 .55 .33 .53 Brass

That should work for the upper fitting.

NAPA uses the 402X4 part numbers at my local place.

402X4X4 might be useable to make the lower fitting and delete the oil pressure switch but I've never tried it however.

Verify with the search feature exactly what NPT size goes into the block for the lower fitting if it's the one that's shot.

But if you've had it off you should know the size if you see it at a parts store.

Thanks for all the responses guys. I wasnt able to read this till now. I went to Kragen and the guy let me go through his drawers. I found 1 fitting. I was happy as hell!. I went and put the new fitting on, and now this one leaks too! It leaks between the nut and the tube, pretty bad. This is a new fitting, and given its a new brass piece, the steel tube should have crushed and formed a seal in there. But it WONT! WTF is the trick to making this work? I didnt tighten it too tight. Started ip up, and it leaked. tightened a little more..it leaked. tightened it about as tight as Im going to get before the piece is shot, and it still leaks. The flare on the tube looks ok. I dont get it.
Blown&Injected- Your comments show what little machining experience you have. This is not NPT. The one that goes into the turbo center section is obviously 1/8NPT, but the hard line uses a straight thread, just like a brake line. Its a flared line that crushes against a conical seat in the fitting, and its SUPPOSED to seal that god damn piece of **** mother ****er...not you, the god damn car.

Oh, don't be such a stick in the mud, go drop by Lou Czarnota's shop & wish him Merry (belated) Christmas & tell him what you need. I am sure that he has one somewhere, and will give it to you "no charge". If you want to "accidentally run into him" sort of like, he has a new GN to play with and will have it at Donut Derelict's tomorrow (Saturday) morning. There will be some nice cars there tomorrow. Last week we had 10 turbo Buicks & 2 TTA's there.

leaky

O.K. I think you may of went wrong when you went throgh the guys drawers at Kragen. So now I would drill the fitting out and tap it to pipe thread and get a fitting from napa that goes from pipe thread to compression fitting ,cut bad spot off end of tube de-burr and Tighten. That the best I can offer.

 

[VadersV6]

Wells- I'd rather shoot myself in the balls.

I have the fitting, but it still leaks.
I looked inside the elbow, and the steel tube had crushed a nice ring all the way around that little cone inside the elbow, so I cant tell for the life of me WTF is happening here. I didnt see any cracks anywhere. If all else fails, Im going to have to jam a bunch of JB weld in that seam, just so I can get going temporarily.
Is there any kind of special grease or sealant or something I dont know about, that mechanics use when they do brakes?

 

[Blown&Injected]

Your description in the OP sounded like you were having trouble with sealing the threads on the elbow and you described a thread count of "like 28" and since the part you loctited and screwed back in made it appear that the male threads were the problem.

Please do not attempt to GUESS my level of experience especially based on your lack of understanding of an inverted flair fitting.

There isnt enough meat in that fitting to go and open it up and go to the next size pipe thread. This thread is larger than 1/8 NPT.
I just need to know if there is some sort of goop that you use for doing brakes or whatever that is intened to stop leaks like this.

You can machine high level stuff every day, and still not run into every type of thread there is. I did my best by matching the threads up to a tap, and explaining that this is like a brake fitting. Ive had no interest in doing brakes in my life..Ive done like 2 brake jobs, so Ive never bent and flared tubing, and used these kinds of fittings. It doesnt matter. I'm stuck here and the "inverted flare fitting" (which its not called...called a line fitting) is leaking. Whats happening is, somehow the oil is seeping outside of the crushed seal, and bleeding inside the nut, and then dripping outside.

Ok, sorry to hear that you are having problems, and I hope that you find a solution. How about Sod & gang at Hy-Tech Performance, they would probably have a fitting.

 

[blkrs86]

all flared up

relax ...if the fitting is o.k. (threads and seat) you can go to napa and get brake lin of same thread say 12" long carefully bend and find a place to put a union ,cut both lines and connect.Go to work and save up for new stainless line.I wouldn't "goop" it up cuz dont want to send any up to turbo....or just drive the S.O.B. and watch it go up in flames when the oil cathes!!!
