Thread: Where to buy turbo oil drain barb / bung? Also 90° or straight?

Yah you know what I figured out? While I was at Lowe's I found all this MPT, MIP and FIP crap but no NPT... Apparently they are all the same thread type...

The guy who worked that aisle had no clue either, kept scratching his head. Soooooo yah, I'm dumb.

I'll just leave this here since it would be of great help for someone else who has this question.



It's Vadim's Avenir T25 setup and gives a real good idea of what you're dealing with on the turbo drain. It's also good to note that while it's not obvious in most pictures, the drain spot is raised off the block and angled about 45 degrees to begin with. This makes a 90° fitting basically useless. I still haven't gotten around to this part of my build yet, but I bought a straight piece and a 45° piece. The 45° piece should point straight up when in the block, it's just a matter of if that works with the drain coming off the turbo. We'll see. I'll post results when I'm done.

I've got a new setup on the way... ATP carries a drain flange that is flat and threaded with a 1/2npt thread, and i had them send me a 45* 1/2npt to 5/8 barb fitting. We'll see how it works out.

I can't use my factory drain, you want it?

Naw, I think I'm covered in that area. Thanks though.

NP, it's just sitting, so if you experience frustration, I'm willing to toss it your way. I know that both my T28 and disco have been (read: still fighting with it ) a pain in the arse for this.

I finally got mine worked out... basically duplicated the stock one in pieced fittings... here's a pic:


It's an ATP 1/2npt threaded drain flange, napa 1/2npt 90* male to female and napa 1/2npt to 5/8 barb. Hope this helps someone. Lines up nicely with the center section clocked slightly towards the block.

Yeah the last guy said something about that. I think I use ACE now. Localest.

I've finally gotten around to doing this. There's no way a 90° or 45° fitting is going to work. I had to use the straight fitting and it worked great. If I'd realized the surface you drill and tap was already 45° off from the block I probably wouldn't have bothered trying to "make things better". For all those wondering the same thing I was, the straight piece is really the only option for a bottom mounted turbo.

I'll have pics later.

I think it really depends on turbo fitment, too.

For instance, I need a 90* that has the inlet clocked towards the crank pulley, but just slightly turned up, so probably like 80*.

I'm talking about the fitting that screws directly into the block. You have a 90 elbow there?
