Oil temp bung placement?

[Toni]

Got the oil pan out and looking to add an m12x1.25 bung for an oil temp sensor. Any suggestions on placement? This is where I am looking at right now. Nice flat spot toward the rear of the pan. I'm assuming the lower the better to catch temperature when the fluid is low? So basically where the pan starts to get flat.

I'd prefer to place it in a place that has flow.

[Toni]

Well, the pickup is right there...

[Chris@Rvengeperformance]

usually I see them mounted near the oil pump housing, you can tee off the oil pressure fitting. Ideally I'd think coming off the oil filter housing would be best.

Standard fittings locations won't work well as I have a straight threaded sensor with a washer. Much like a drain plug. Also, I believe those locations are after the cooler so you aren't really seeing how hot the oil is getting.

Well I drilled and tapped my drain plug for mine. It's where the stock sensor is located on the Evo so I figured it was a good spot.

Hmmmmm...wonder if the evo plug would just thread right in http://www.rllmukforum.com/public/style_emoticons/default/eyebrows.gif

Annnd done... Welded a nut to the back of the pan. Flattened out the front with a file. Should have no problems with the seal.

It would if you drilled and tapped the drain plug for it.

LoL, no...i mean using the evo plug thats already got the sensor in it :p

looks like the evo thread pitch is M14x1.5...

that is the same pitch as ours

Cool idea. I may have to pick one up.

Interesting info! Just need to know how to read it. Since there is a single wire I am assuming it's resistance based so it will need some components in order to scale it to 0-5v for input on most logging systems. I have a dedicated gauge so I'm going to stick with what I have now.

Agreed...i also was thinking gauge instead of logger :wink:

[anyonebutme]

I have the EVO sport gauge kit on my car, works great.

[aaronatstate]

Yeah to use the Evo drain plug you need the evo gauges.

[familyMAN]

Would the sender not work for other gauges?

[Toni]

Alright, I think I am happy with the placement I choose.

yea thats a pretty sweet idea(evo drain plug/temp sensor) but idk if i would want to get rid of my magnetic drain plug.

Using tranny coolers you want to install the sending unit on the return line. This way you see oil temps after the cooler being pumped back into the tranny(or engine). I like this idea because you can see how efficient the cooler is, and know what oil temp the engine is actually receiving.

I just don't see how the oil pan is very useful, of course its going to be hot, it just came out of the engine. I don't know I guess I'd be arguing with the engineers of mitsubishi lol

I'm not a huge fan of them, especially since they're going to be right by the pick up. Would be my luck that some of the metallic sludge would get sucked into the motor and devour turbos or something :P Had a question about the dilution and iron PPM for the Saturn. Namely, were they including the iron accumulated on the magnetic drain plug in their results or just what was in the oil? If they included what was on the plug and just doubled amounts couldn't that skew the numbers since it accumulates there rather than exiting with the oil that is consumed? I just find it odd that it pretty much doubled compared to stock despite adding nothing. Are they saying that the wear metals would be leaving the engine due to burning oil (ie. exiting the motor during the combustion?) If so, wouldn't the plug be holding onto most of the iron metal and therefore they would be throwing off their results?

They don't indicate if the chart on page 2 has the corrected values or not, or the graph later on. I would guess that they did correct for that aspect of it properly in which case it seems to have made little to no difference. I suppose the biggest issue, IMO, with a magnetic drain plug is that it can't capture any of the bearing material (as it's non ferrous), or some of the other possible signs of wear. Capturing iron may be of value, but capturing bearing material would be better since if you're getting excessive wear to the cylinder walls, pistons or crankshaft then you're probably going to see bearing wear first. Or maybe I'm just totally over thinking this.
