Turbo oil feed line thread

[Tonny132]

Hello guys,

Can someone tell me if all these threads are the same and what thread they are.

Kinda hard to answer just a vague question. On the OFH? Stock turbo? Joint in the factory line? Feeding from the head?

There are several "Turbo oil feed line" threads listed right below this post, by the way.
If it feeds from the oil filter housing it would be a 3/8" BSPT thread. (2g)
If it feeds from the head, it uses a banjo bolt and crush washers. (1g)
I don't know the size of the banjo bolt but someone will chime in.

This also has good information -

Hello guys,
I have a 1997 GST spyder and removed the stock turbo. Now I have to known what thread size/pitch this oil feed line has.
