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

Will a auto transmission cooler from a ED falcon fit an EF falcon


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

Excessive oil leak in ford falcon ef


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.
