Tehnation Posted September 8, 2021 Share Posted September 8, 2021 So i'm trying to see if one of those front oil plugs can accommodate an oil temp sensor. Here is the post from my rebuild thread. If anyone could put eyes on it and let me know how much room is around them that would be amazing! https://legacygt.com/forums/showpost.php?p=6042778&postcount=743 Anyone think I can fit the temp sensor in one of the front oil plugs?? Would it hit the timing belt cover? If anyone could just take a look and visualize or measure which side has more room so it can stick out without interfering with anything that would be awesome. Its the one with the wire. [ATTACH]293260[/ATTACH] [ATTACH]293261[/ATTACH] Its about 1 3/8" long (about 1 13/16" with the oil plug adapter) and about an 1" width(I could make it a little bit smaller if need be).

JmP6889928 Posted September 8, 2021 Share Posted September 8, 2021 Put this in your DS OCV banjo bolt hole and then use adapters to fit your OTS. https://indyautoracing.com/12mm-x-1-25-banjo-bolt-w-1-8in-npt-port/?gclid=CjwKCAjwvuGJBhB1EiwACU1Aidjbk4jYV-MYY0iQ2iXiC0UxDCBDwbnmbWwqEZgTlC5q0o7vmKi-EhoCVmUQAvD_BwE Link to comment Share on other sites More sharing options...
Tehnation Posted September 8, 2021 Author Share Posted September 8, 2021 hmm I'm worried the sensor has to go in about an 1-1.25" so it will actually cover the side holes. Link to comment Share on other sites More sharing options...
Tehnation Posted September 8, 2021 Author Share Posted September 8, 2021 the threads for the sensors are already 1/8 npt so no adapter needed, it would go straight into that banjo and then sink in an inch or so. Link to comment Share on other sites More sharing options...
RacerX69 Posted September 9, 2021 Share Posted September 9, 2021 I welded a bung in the side of the oil pan on my racecar to place the oil temp probe. Saved having to adapt it elsewhere. Link to comment Share on other sites More sharing options...
Tehnation Posted September 12, 2021 Author Share Posted September 12, 2021 (edited) I'm still going for the front one lol, until I see otherwise. But I just put the cover on to see how much depth I'll have. From what I see so far, I don't understand how anything would be a problem, it can squeak by imo. The accessories ac/powersteering/alternator need to go way past the cam cover so belts and stuff aren't the problem, looks like mounting brackets. I'm thinking if anything I could grind down some of that nub which the timing cover bolts to. Its only holding a low torque small bolt. Hmmm, I will see what I'm working with when I install more stuff. Edited September 12, 2021 by Tehnation Link to comment Share on other sites More sharing options...
JmP6889928 Posted September 13, 2021 Share Posted September 13, 2021 As RacerX says, bung on oil pan and I completely agree. That's how we measure on race cars too. That way, your sensor is right in the thick of the oil rather than having fast flowing past the sensor. Simple to do and will always be consistent unless you run it completely out of oil.

Tehnation Posted September 13, 2021 Author Share Posted September 13, 2021 (edited) from my knowledge the main factors are pre and post oil cooler temps. Its more so a matter of preference to what your looking for. But the oil pan is a nice spot in general to get good temp readings, so I guess you guys are right for it being a good spot for general consistent temp, cause I don't really know how the oil flows to determine which galley would be best, I prefer post oil cooler temps!...... but drilling holes and all that nonsense? I'm thinking something a lot more practical and simple. Ah and it just hit me!!! Whats the thread for our oil pan bung? Simplest solution no drilling or fuckery, i'll just get a plug that threads to the pan and has a 1/8" npt. Basically something bigger than the one for the oil galleys. I was hoping they were the same size but its slightly smaller. If we could find that piece in the picture that fits our oil drain then its a simple one piece solution no drilling and destroying oil pans etc. Edited September 13, 2021 by Tehnation Link to comment Share on other sites More sharing options...
Tehnation Posted September 13, 2021 Author Share Posted September 13, 2021 and the temp at the bottom of the pan is what the pickup is sucking so its a good place to get a reading for the pre cooler temps. Only drawback I can think of is you need a wrench instead of a socket to change your oil. Link to comment Share on other sites More sharing options...

Tehnation Posted September 14, 2021 Author Share Posted September 14, 2021 (edited) Hmmm.... Is there a place to get a custom piece like what I'm looking for special ordered? Basically a M20 x 1.5 Flanged bolt with a 1/8" NPT Sensor port. Surprised no one has it already..... Am I missing something? So I am ordering this adapter and some washers. https://www.amazon.com/GlowShift-Female-Sensor-Adapter-Reducer/dp/B07D7GPML1 https://www.amazon.com/Pieces-Copper-Washer-Gasket-Metric/dp/B07J2DL3KG?th=1 Hmmm I think I want bigger washers.....

Tehnation Posted September 17, 2021 Author Share Posted September 17, 2021 (edited) Hmm... thats not a bad idea, take a stock drain plug and have them drill a hole and tap it. But i'm not familiar with any shops around here who do that kind of work. I got the pieces but it looks like the sensor is hitting that basket thing inside the oil pan..... more shenanigans... the top and bottom nut need to be flush against each other, shouldn't be able to see the thread tape. I think I would run into the same issue as the killer b plug as well? ! It is basically the same thing I bought just another metal. Killer B https://www.killerbmotorsport.net/oem-to-1-8npt-oil-temperature-sensor-adapter.html.html What I bought https://www.glowshiftdirect.com/m20-x-1-5-male-to-1-8-27-npt-female-thread-adapter/ Sent an email to killer b to get the total length of the adapter.

Tehnation Posted September 18, 2021 Author Share Posted September 18, 2021 (edited) So I also ordered that ocv banjo bolt with the extra port on top that Jmp recommended. It looks like i need some kind of extension or something. Thats as far in as it can go. So this is still on the table if I can get the piece I need.

Tehnation Posted September 18, 2021 Author Share Posted September 18, 2021 (edited) Found it! The internet has everything! https://www.amazon.com/EDGE-INDUSTRIAL-Extension-Adapter-Approved/dp/B07DP4HGM8 https://www.amazon.com/EDGE-INDUSTRIAL-Extension-Adapter-Approved/dp/B086N32DSP The sensor is about about 1 1/8" with the threads , trying to figure out how long of an extension I should get. I will start with the 1 1/4" extension! Should be here Monday. Edited September 18, 2021 by Tehnation Link to comment Share on other sites More sharing options...
Tehnation Posted September 18, 2021 Author Share Posted September 18, 2021 (edited) And then I find this! Exactly what I wanted something with a bigger head to give me the room! https://www.rallitek.com/oil-adapters/7465-killer-b-oem-to-1-8npt-oil-temperature-sensor-adapter.html Why don't I see this style on the Killer B website? The thicker head should give me the length I need to avoid the metal basket thing. Must be old stock! Its made from an oem plug. Hmmm, I wonder if the picture is just old and I will get that new one they are making.

Tehnation Posted September 18, 2021 Author Share Posted September 18, 2021 Also ordered this https://www.amazon.com/Anderson-Metals-Fitting-Adapter-Female/dp/B000BO9CJ0 this would remedy the oil pan plug problem. I like options. Link to comment Share on other sites More sharing options...
Max Capacity Posted September 18, 2021 Share Posted September 18, 2021 Just saying, you should be able to find common brass fitting at most hardware stores in the plumbing section.

Tehnation Posted September 18, 2021 Author Share Posted September 18, 2021 True, but i'm limited to places like home depot/lowes level, and I prefer to sit on my ass and get free 2 day shipping from amazon, i'm near a hub I think because I get things hella quick. Also makes sharing the info for the next guy a lot easier. No rush for me, I got enough on my plate, playing with my subaru is like therapy lol.

Tehnation Posted September 19, 2021 Author Share Posted September 19, 2021 (edited) All the 1/8 npt stuff at home depot is special order... So the piece I got for the oil pan plug doesn't work, this sensor has to use an extension piece. Edited September 19, 2021 by Tehnation Link to comment Share on other sites More sharing options...
Tehnation Posted September 20, 2021 Author Share Posted September 20, 2021 Everything failed.... looks like I gotta find a store. I need an adapter that has like an inch and a quarter of 1/8 npt female thread to hold the entire sensor. All these adapters get narrow after the threads so the sensor cant get past the bottom of the threads. Link to comment Share on other sites More sharing options...
