I had a very persistent oil leak on the front iron fitting that feeds oil to the turbo. I was using a 04AN to 1/8NPT straight flare fitting, without any type of washer, just some plumbers tape; that obviously didn't work. As a temp fix, I used an O-Ring that I found on my toolbox, and it seems to be working; however I don't really trust a rubber o-ring that has been crushed to death!

So here is the question, are you guys using any type of washer (copper, crush) on that fitting?

BTW - This is the fitting that I am talking about:

 

I'm pretty sure I used teflon tape on that fitting. It's the pipe threads leaking right? Sometimes I've used a yellow plumbers tape that's for gas lines, it's supposed to hold up to gas, oil and other chemicals better. Once I used an o-ring to seal a fitting like this and it only held for a couple months before the heat made it crack and leak. I then used a bunch of that yellow tape and haven't had any problems since.

You could always JB weld it lol JK

 

That thread hole is straight not tapered, parker fittings makes a straight thread metal incapsolated o-ring fitting and it will never leak again and viberation will not bother the fitting.

Im sure other mfg also has the same type fittings. I also got a 90 deg fitting and it saved space and looked cleaner!
Good luck!

 

He nailed it. The threads are straight as are most holes it engine blocks. I used a copper washer in between the iron surface and fitting....

 

I just used the stock copper crush washer and it seemed to fit fine.

 

I love my parker fitting store there great.
I dont even use silicone tubeing any more i use high pressure plastic tubing with swivel push connects. Its super fast to disconect does not leak and you mold it with a heat gun and it holds its shape. I even run it on the wastegate with hi temp sleve!

 

This solved my leak at the front iron.....made a damn mess in my engine bay without it

 

All,

THANKS for the info!!!

 

Need more info, like part numbers, etc

 

I was afraid someone would ask im going to have to work on that as i did almost 2 years ago!

 

Take your time, my setup is already done

 

a crush washer will help, but also IMO teflon tape is worthless for those types of fittings. Once you tighten it down the tape just screwed up. I have had very good luck with a thin coat of black RTV.

 

Comes in all a-spec kits !!!!

 

Also when using teflon tape (not suggested with proper fitting) you need to be sure to start a few threads back, if you don't and it gets into the line it will eat your turbo. I've gotten two 35R's back from customers who did just that

 

Thanks for the info!


Hopefully it not too late for me
