MG TD TF 1500 - XPAG/Jaeger oilpan bourden tube adapters

I recently purchased several mechanical Jaeger accessory Oil Temp gauges. They did not come with the necessary adapters to fit the drain plug hole. Iím now in need of the adapter fitting X2. My internet searches have had no joy. Does anyone know a source for these fittings?

Bill,
Does this not work? The same fitting in the Rad. Did you try to fit your existing rad one to the sump to see if it fits?

49 361-050 $15.99 ADAPTOR, temp. gauge line to rad. (male/female) 1

or

361-060 $15.99 ADAPTOR, temp. gauge line to rad. (male/male) 1

Rod I have not tried the rad adapter that was sent with one of the gauges I received. I believe the oil drain plug is larger. But until I do my next change I wonít know for certain. The owner of FRX 942 will be sending me pics in the coming days so I will have an example to work

When I first put my 53 TD together in 72 I had an adaptor in the Sump Oil drain hole. The one that fits the rad and the water temp gauge I thought was the same.
When I put the car back to STD in the 80's I just refitted the drain plug and did not refit the old Oil Temp gauge in the dash. The thread in the sump should be BSPS Don't know the actual size but 1/2 inch sounds right. The other side of the Moss Male/Male adaptor should fit the Oil Gauge bulb nut. Maybe that is what you have?

Rod. Iíll have to see if I have an old drain plug to campare it to. You may be right and Iím making a wrong assumption.

Rod I had received a gauge from Ed McCord that had the correct adaptor with it. I just compared it to a oilpan and the thread is right. I then went out to my stack of radiators and the adapters to the top tank are smaller male thread so the radiator adaptors wonít work. Pictured is what Iím looking for though I cannot identify the oilpan size and thread count.

Bill, if your sure you want the oil temp gauge in your car as a permanent configuration. I have another suggestion for fitting the sensor in the oil pan. Instead of adapting it to the drain plug, consider using the hole in the pan that currently has the clutch pivot shaft on the other side of the pan that is not used on the TD linkage. After removing the old pin, I bet there is enough meat around it to permit drilling and threading for the sensor adapter. Once you locate an adapter to fit you sensor bulb, you can determine if the pin hole surround is meaty enough. Yes, its a little high in the pan, but I believe the hot oil gets slung around enough to made it work accurately.
If your willing to modify the pan, this would make oil changes a little easier, and keep the sensor tube a little higher from any possible damage due to road trash.

Just another possibility?

Richard thank you for your suggestion but my cars are all LHD and to use the right side pivot stud area would aggravate any readings due to the proximity of exhaust heat. Also I want accurate oil temps not ambient crankcase air temps. Iím thinking that oil windage being thrown against the bulb and hot gases in the crankcase would show what would be an abnormally high temp reading. I donít know this as fact but just as a thought. Finally, Iíd prefer not to modify an otherwise exceptionally nice oil pan. But it could be viable option for others and it is duly noted

Tom Lange. Since you make magnetic plugs could you tell me what the oilpan plug thread size and count is? Is it BSP or some other pitch? Is it 1/2Ē BSP-14?

Okay. I think Iím close to finding the adapter I need.

Looking at Chris Couperís site the oil drain plug is 1/2Ē-14 BSP. Can anyone tell me what the thread size is for the bourden tube retaining nut on a Jaeger temp gauge. Ití should be the same as used on the water temp gauge

Bill,

If you are concerned with the oil temperature, have you thought of fitting an oil cooler. You can then fit the temperature sensor in a T piece at the outlet of the oil filter. I don't think the putting the sensor and tube into the oil drain plug is a good engineering solution.

Bill,

Just went thru my parts drawers and found this one that I was going to use but decided not to bother. I'm pretty sure it works (hit the tube with a flame for a millisec and it jumped up) so I don't want to sell just the adapter but if you're interested I'll sell you the whole unit at a decent price. The gauge is darker than the picture but you may be able to clean it up...or use yours and sell this one.

Contact me via my email address above.

Thanks Gene. I will be sending you an email directly.

The one thing you don't want to be doing is disturbing the tube every time you change the oil.

I remember seeing two engines with temp gauges fitted, with different arrangements. One utilized a through-fitting in a new hole drilled in the sump about 2" above the pan bottom, with a retaining nut on the inside. That way the oil could be easily changed without affecting the tube.

The other had a wedge-shaped brass plug adapter into which the tube fit, with a small screw at the bottom sealing a passage for draining the sump.
