Second picture is where your oil pressure sensor goes, it is actually a 1/4" hole for a sending unit if your running an oil light or use a 1/4" -1/8" reducer if you are running a pressure guage. Like the one I have pictured. Hope this helps.  |
Good pictures....The tapped hole in the block for the oil pressure sensor IS
1/8-27 tapered pipe thread though, not a 1/4" hole.
1/8-27 thread mics up as .390 O.D. 1/4" is .250 O.D.
