Default Crate engine: Turbo oil feed tapped at right place?

Man I feel like a loser on this one. I hope this makes sense..

I noticed some "newer" oil under the intake manifold where I've T'ed into the oil pressure sender port (or thought I did). There seems to be two options here, and maybe I re-installed in in the wrong one (?) (!)

I have it installed in the top of the two options, closer to the manifold. The one on top is also sticking out from the block a bit (like the factory oil tap everyone else uses). I did pressurize the engine for tapping the pan, would that cause a bit of oil to come out of the port if the sender was missing? It would, I know..

Here are some pics, best I could do in the space:

I can't search anymore, make it stop. I found the above. Presumably a 1.8. Where the hell did I put the sensor? What's the hole for? heh.

if you didnt have it in the right hole you would see alot of oil when you tried to start it heck i had mine abit loose and it still spewwed everywhere. so just run it for a sec and see if it spews nd is tight then use the other hole.

Default Pictures.

I'm 99.9% sure it was in the wrong hole. I haven't even tried to start my car (good thing hello? this thing on? ), the build is still in process.

After the above link, which shows the unit more or less "in-line" with the freeze plugs, and another visual confirmation on section 2, page 6 (2:6) of the "Mazda Miata Enthusiast's Shop Manual" showing the same orientation with regard to the plugs, (1.6 specific) I must conclude the lower of the two holes is the correct one.

Look at how clean the lower one is. Who knows what the other is for?
Think I'll write a how-to in this thread in case anybody else out there is as smart as me..

Probably a water/coolant port. That's the configuration on the other side of the block where we get oil feed on the '90-'95 cars.

Default How-to: Oil feed line for your crate engine (no factory tap)

Ah, there it is. Thanks, Brian.
Well, here are some brief instructions for someone who doesn't know they need them yet. Numbers coincide with the pictures.

1. Locate your oil pressure sender. It's hidden underneath your intake manifold.

2. Remove the fragile plastic clip attached on the end of the sender.

3. Use a deep 1 3/16 socket.

4. There are a few lines in the way, the angle is slight. The solution.

5. Remove.

Con't.

6. Remember which port you removed the sender from.

7. Here is the sender. Attach your "T" adapter between the block and the sender.

8. It should look like this when all assembled. Install the adapter into the block first, then attach the braided oil feed line.

9. Maybe this should have been first, but this worked perfect so you can see what the hell you're doing. It also helps to know what the hell you're doing.

Have a good one.

Size: 1/8 BSP male to fit into the block. 1/8 NPT for your oil feed line.

The oil feed is done. I had originally ordered just the adapter. Then I ordered the kit from the same place, which came with another adapter.

When I installed it in the wrong port, it stripped somewhat. Lucky I had the extra adapter because now I feel better about it.

I'm uploading a little vid on YouTube...
