STR8OUT or other who used the oil gallery for a gauge -

Do you think the gallery at that location was open/deep/roomy enough for a oil temperature sender? The sender is maybe 3/4" long by 1/8" in diameter.

Note: yes - I know that a sender can be put in a drain plug or a sandwich block. Neither provides a temperature that the oil experiences when it is actually being used by the engine. The oil cooler is at the filter and the oil goes through the cooler before it would go through a sandwich block adapter and the adapter would just put the filter even lower to get hit. The drain plug is getting temperature of oil that has been in the pan a while and just getting ready to go back into the pickup and also the wire could hit or snag on something.

You can use the stock oil pressure sensor location and a 1/8" T with a 45 degree brass elbow, and it'll just fit under the alternator, as long as it points back towards the passenger front strut tower.;)

Thanks that was where I was going to install the aftermarket oil pressure sender though on a T to still allow the dummy light to function.

I have the gonkin' huge Autometer oil pressure sender there- a temp probe should fit no problem ;).

Pressure senders are all external though right? I am trying to figure out if the gallery has enough room inside for the temp sender.

:confused: you want to take apart your motor to put in a pressure sender?

No. :)

The stock oil pressure dummy light accesses the front gallery just behind and underneath the alternator. I am going to use that access point (hole already in the block) for my oil pressure gauge. You have to remove some of the accessories to get to the block but you don't take the motor apart. :lol:

In front of and just below the TMIC is a plug in the rear oil gallery that some have used for attaching aftermarket oil pressure sensors (see at scoobymods). I want to put an oil temperature sender there and am trying to find out from someone who has put a pressure sender there if the gallery in that area is of sufficient size to allow the intrusion of a temperature sender.

Why don't you just use the top access plug for the oil pressure instead of moving everything around?

I am using the top access plug for the oil pressure - I am using the same access plug used by the dummy light sender in front of the block. I want to use the rear top access plug (the one I assume you are referring to) for the temperature sender. Not sure what you are saying I am moving all around.

Your initial post was a little confusing. I thought that you had not put any gauges in yet and wanted to remove the factory dummy sensor to put in the oil pressure and move it to the top gallery hole under the intercooler. Unfortunately, the only way that I've seen done is to use the oil drain plug, which you've already indicated you don't want to use. Good luck though!!

No I have a T connector that will allow both the aftermarket pressure gauge and the stock dummy light gauge to run from the front access. I never said I was moving the stock pressure sender.

I want to put a temperature gauge in the back access instead of a pressure gauge like most do. I don't think the question I posed at the start of this thread is unclear.

I asked about a TEMPERATURE sender fitment and everyone keeps talking about pressure gauges.

My question is straight forward and simple: Does anyone that has actually used the rear gallery plug know if a temperature sender (about 3/4" by 1/8") fit in this gallery location?

Dude. . .calm down a bit. I was only trying to help. . .no need to get all pissy about it. I misread your initial post. . .pardon me for trying to help someone out while I'm at work. :rolleyes:

As for mounting the oil temp, I don't think you can reliably use the gallery plug at the top of the engine because it won't be completely submerged. It would only get submerged when there's enough pressure in the engine to push the oil up onto it. If I were you, I would either just swap the oil pressure and oil temp sensor locations or just tap the drain bolt. The oil may have been sitting there for a while, but keep in mind that the oil is circulating and should have just come back from the engine. I can't see the temps being off by too much.

For a straight forward answer to your question, the sensor should fit since the gallery plug itself is about 3/4" deep. Whether or not you get a good reading though is a different story.

Thanks for the thoughts on whether or not it would be submerged and in contact with the oil. That is something for me to think about. I went back and installed the sensor in the gallery plug and I see that it only extends a bit past it. If the plug fits and oil flows by it then with the sensor in it should be fine.

I would think that it would be in contact with the oil under pressure since people are using pressure gauges in that location and getting pressures as low as 10 psi.

I think my intended installation will work it appears, thanks for getting me to go see how far it went through the plug.

As far as tone, I think I was calm and not at all pissy. I was pointing out that I didn't see how it was confusing. I take great pains to try and make sure that I communicate on these threads as clearly as possible and edit at least twice before posting - though I do still mess up, especially when tired. But I was not upset simply pointing out that I thought the post was posed in as clear a manner as I was able to articulate.

I appreciate any response from those who take the time to answer my questions. And your last post got me to try something I should have tried originally, so it was helpful and I do appreciate it.

No worries. . .tone is hard to differentiate on boards since I don't know you personally things are easy to misinterpret. :)

Happy to hear you got it figured out though.

Oil pressure remote mount sender hose installed in the gallery plug used by the stock oil pressure idiot light behind and underneath the alternator. (Please always disconnect the battery ground when messing with the alternator hot wire.) When I get the T-fitting I can have both the stock and aftermarket oil pressures off this same tap.

Oil temperature sender installed in the same location that STR8OUT used for his pressure sender. It is plenty deep enough.

It looks like you're leaking a little oil on the oil gallery plug under the intercooler. You can see a pool of it on top of the block right next to the gallery plug. I had the same issue when I installed my oil pressure gauge. . .turns out I had to tighten my oil pressure sensor another 1/4 turn or so.

Picture was taken before running the car after the install. I think that might be a pool of WD-40 and gunk on the block. Will check after I have ran it for a while. About the time Vishnu gets and delivers my new TMIC should be about the right time. Will keep an eye on oil level (and pressure and temp :) ) until then.

Thanks.

What threading was your oil pressure sensor? My actual sensor which I remote mounted was M10X1.25 - the tap in the plug is 1/8 BSPT (or 1/8 PT) which is the same threading as my temperature sender and the coupling for my remote mount hose on the pressure sender. The M10X1.25 will thread about 3/4 of a turn into the plug but would be cross threading after that. I was able to hand tighten about 80% of the way into the plug with both my temp sender and the coupling before I installed the plug.

I'm using a Greddy gauge so it matched up perfectly with the gallery plug since they're both 1/8" 28-turn BSPT. I didn't get it tight enough initially because my wrench was hitting the rubber hose from the PCV. When I checked it a few days later, I saw the oil and tried to tighten it a bit more and it went another 1/4 turn or so. Cleaned up the oil and haven't had a problem ever since. Are you sure it was cross-threading? I know that with a BSPT tap, it tapers as it goes down so it's like this: \ / so you may be just meeting up with resistance from the tapering.

Yeah my sender definitely would have cross threaded since it is a straight M10X1.25 - but any sender that is 1/8 PT (Japanese tapered) or 1/8 - 28 BSPT will fit right in they are equivalent. Not sure why Omori made their sender with that thread unless they wanted you to always remote mount with the adapter and hose. It works out well for me anyway.

I will clean out the area on the rear gallery plug around my temp sender and check again when I swap ICs. Thanks for the feedback on the pics.

If it is leaking, you could use some thread sealant on it or teflon tape, whichever you prefer. Just use some on the upper threads so that none gets into the engine.

I think I will be good to go, torqued down pretty well and had proper crows foot and all. But it wouldn't be the first time I had a fluid leak, easy enough to fix.

BTW - my theory was just about completely debunked on the temperature difference. Warming up sitting at idle, the gallery will read warmer than the oil pan but as it approaches operating temperature there is little difference. This is without any cooling that happens from airflow over the pan (which probably isn't much) and also without the mixing that would occur during movement. Pan gauge 90 celsius - gallery gauge 195 fahrenheit.

This also debunks a theories (from quite a few people I contacted) that the sender would not be properly submerged. Under pressure the gallery is filled and the sender is submerged as illustrated by the temperature and your leak. :) I arrived at the appropriate temperature even as idle pressure fell to around 25 psi.

Anyway, plenty was learned and I didn't have to lower my oil filter even more with a sandwich and I don't have a probe and wire hanging from my oil pan (well at least not once I switch the oil drain plug to a solid one).

Thanks for the interaction and input during this cnk.
