Re: Oil leaking from thread of oil sensor on ef falcon.
Possibly,the sealant used should be the white teflon that comes in tape form or as a liquid in a small squeeze bottle.The liquid form,you would want the threads free of oil,the teflon tape,oil present doesn't matter,although the tape should be applied to the threads in the opposite direction of the threads.The threads would screw into the block clockwise,so apply the tape from the counter clockwise direction.It is also possible that the sending unit itself has a small crack somewhere,and these sending units aren't all that expensive,so i would install a new unit while using the teflon.

This requires careful application of an ez out or thread repair kit very likely these are tapered threads and in aluminum. can be tricky and should be attempted by someone with previous thread repair experience, the pipe must be removed and if the threads are not damaged you can just clean up the area and re install a new sensor ( thread sealing tape is often used) you must not get any of the tape in the oil galleries or it can plug up the flow causing engine failure. pay the money now to have it fixed correctly, or ensure who works on it is knowledgable or the cost will be considerably more, torq the fitting to the proper spec not till you think it is tight, good luck
If it is in the radiator it should as the fittings are the only problem you are likely to encounter. If you are wondering if the cooling capability is affected consider this . Hot tranny oil has to be cooled in the radiator water and this heat makes the radiaror work hard.Why don"t you consider a external cooler. They keep the oil cooler as they are are running in the outside air. Ie air temp 30 deg C oil temp 150c+ water temp 85degC oil temp 150c. You can see that the tranny oil looses more heat and it will not overload the radiator capability
Have the engine pressure washed, then drive it for about 10 miles and check the source of the leak. Drive at low speeds so air flow doesn't blow the oil all over and make it harder to see area of leakage.
recon job poorly done. sounds like a gasket or engine/tranny seal. is there moisture droplets on the oil dipstick? How often do you change the oil? if you change it every 3 thousand miles or 3 months faithfully, and it is not leaking oil (you see no puddles under the car) onto your driveway or street where you park it, and there are no globs of black gunk on the underside of your car anywhere, then someone could have dropped something into the engine compartment somehow, through one of the spark plug holes, when the oil cap was off, etc.
Disconnect the electrical connector from the oil pressure sensor.
Using J 41712 or equivalent, remove the oil pressure sensor from the fitting.
NOTE: Note the orientation of the oil pressure sensor fitting before attempting to remove it. This is so it can be installed in the original position.
Remove the oil pressure sensor fitting, if necessary.
To Install: NOTE: If the fitting has been removed, clean and apply sealant to the threads before installing it.
Install the fitting until snug, if it was removed.
Tighten the fitting to 11 lb ft (15 Nm). Continue to tighten the fitting until in the original position.
Apply sealant to the threads of the sensor.
Install and tighten the sensor to 22 lb ft (30 Nm).
Connect the electrical connector to the oil pressure sensor.
Install the distributor.
Check the engine oil level and adjust if necessary.
Spray lubricant on the unit, to ensure an easy removal.
With a suitable open-end wrench or a socket, unscrew the sending unit.
Make sure area is clean before replacing the sensor. Scrape any remaining gasket material that may be left behind. Use a wire brush or a gasket scraper.
Lube the threads with oil on the new sensor and place the O-ring or gasket on the end going into the engine. Carefully thread the sensor by hand, making sure the threads are even, and you are not forcing the sensor into the block. Using a tool, tighten sensor but not to tight as it could break easily.
Connect the wires on the sensor.
Connect the negative battery cable.
Start engine and look for any leaks in case the sensor is not tight enough.
If the engine has an overhead cam it could be the cam position sensor.If the threads are leaking remove it wrap teflon tape on the threads and re-install it. If oil is leaking threw the sensor replace it.
What color is the smoke ? is it bluish or is it white ?
The blue colored smoke would smell more like burning oil, which would indicate a broken piston ring, ect. the white smoke if it smells of coolant(anti-freeze) would lean toward a head gasket problem.
No you have overheated it ,for what ever the reason ,when it cools down oil pressure should be alright again but iam afraid you have bought someones elses bucket of you know what .If oil light doesnt go out then it wants either a new switch or someone put STP oil thickener in it to flog it ,take it back and get your cash back,Dont forget to have your base ball bat tucked into coat .
Oil travels when it leaks, the most common cause is the cam chain tensioner to the right side of the engine at about the same level as the water pump. You have to remove the bracket holding the power steering pump to gain access. A new seal is required there. Be careful not to undo the entire tensioner, this is spring loaded. Just remove the 13 mm bolt from the centre.
