Drilling out the oil pressure port

[macleanflood]

So I installed a GlowShift 1/8" npt oil pressure sensor and temperature sensor...used two Amazon street T fittings and despite everything no surprise the temperature sensor is leaking oil straight on to my exhaust.

I think I've heard of folks pulling what appears to be that brass plug and drilling it out for additional sensors?

Any advice? I'm loath to unscrew the fitting because it just seems like something I'd completely mess up without a little research.

The fact that its leaking on to the exhaust seems like sort of a win.

No drips o the ground

Locktite 680. Apply to spotless parts, assemble and let dry overnight.

I have no idea what the threads in the block are, but they make things like this.

I STRONGLY recommend configuring a setup that you cannot assemble incorrectly, as once this sets... well, you're better off starting over with new parts.

If you want to be able to do that maybe try Gasoila instead?

My Google-Fu must be weak...good news is yes, that would be perfect but it's out of stock and that website is rife with suspicious clues.

P.S. And one side is M10 thread not 1/8" npt.

Look for oil pressure manifold

I could be wrong but I think the sensors are npt thread and your brass fittings is pipe thread.

NPT is National Pipe Thread. 1/8" - 27. AN fittings, an interesting sidebar came from Army Navy specifications.

I'd remove the original brass plug, drill and tap the top and one other side.

Pretty sure the Amazon street T was very soft brass. I also don't like the long string of sensors. Sticks here in the PNW like jumping up into all sorts of interesting places.

Id start over with some better quality fittings. I bought some hardware from Lowes the other day. 1/4 20 nuts and bolts and you couldn't even thread the nuts on the bolts unless you used wrenches. China bombs.

 

[Rickyd]

I wonder if you have a bsp vs npt issue. Or a straight vs taper thread.

I like the oil temp gauge

Completely agree. Problem is 99 percent of what's out there is Chineseum garbage. You either buy it cheap from Amazon as such, or marked up 1000 percent from a legit store.

So either I need a good source...or I need to make my own...ergo drill the oil pressure fitting on the block.

I am loathe to do that because I don't see ANY replacements short of purchasing a $200-300 rebuildable long block of FB or CL.

Tight quarters down there.

Stop talking.

Straight vs taper I could see.

Allegedly NPT threads... (For posterity's sake this link is a warning don't order these...only one "worked.")

If I'm replacing it I'd like a single fitting with three ports that doesn't cost $125.

Is this what you are calling a brass plug?

Look closer at that sender. It may not be leaking at the threads. And for god's sake, stop mixing NPT with NPT.

Exactly. Help me with my nomenclature...what the heck do we officially call that piece so I can stop sounding like an idiot.

It is a port adapter. Not much different than the fittings you bought to cobble all that stuff together, just happens to be specific to that location. I also suspect if you were to pull it, you'd discover it is steel, not brass. What I don't know is what the male threads are. I suspect they are very likely NPT as well.
