Thread size at turbo oil return

[Larry]

What is the tread size at point where oil return from Turbo goes back into front of block? Thanks Larry

Larry, it is either a 1/2" NPT or 3/4" NPT. Can't remember which, darn mind.
The fitting is a 3/4" OD inverted tubing flare on the other end of the pipe thread.

The opening in the block is a 1/2" npt thread-the tubing is alittle larger like 3/4".

Yep, 1/2" NPT. Just confirmed.
