Hi there colterf! Usually if you have engine oil leaking out of the back of the motor/ tranny bellhousing, it means that you have a rear main seal that needs to be replaced. Now the rear main seal is a pretty tricky item for the do it yourself'er if you are un familliar with the components themselves. Here is a rough step by step of what needs to be done.

  1. Disconnect negative battery terminal
  2. Lift vehicle and place securely on stands
  3. Locate and disconnect all electrical wires, cables, hoses and supply lines from the transmission (including the clutch or fork slave)
  4. Remove the driveline
  5. Unbolt and remove the transmission crossmember
  6. Use a transmission jack to steady and support the transmission ( at this time you may want to drain the tranny fluid to reduce weight)
  7. Unbolt and remove the starter assembly
  8. Remove all of the bolt on the bell housing
  9. Double check to make sure that the tranny if free and there are no morecomponents connecting it to the engine/ frame
  10. Lower jack and remove the transmission
  11. Locate the output shaft at the back of the engine (the seal goes around the shaft and between the block)
  12. If your vehicle has a seal retaining clamp unbolt and remove it.
  13. While on step 12 you need to drain and unbolt the engine oil resivoir to drop it down a 1/2" to access the seal and to also make sure no oil gets dumped when you remove the seal.
  14. Once you have the seal clear use a specialized seal puller to remove the old seal ( a medium sized flathead screwdrive may work as well)
  15. Once the old seal is removed check the seat on the block for any contaminates and remove them.
  16. To install, place the new seal on the seat and firmly push it into place. The seal needs to go in EVENLY! Use a specialized seal installation tool to make sure it is in all the way, all the way arround. If the seal is inserted uneavenly it will most likely leak.
The installation of the rest of the components are in the reverse order. For many people this is over their head. If you are unsure of yourself do not attempt and have a professional do it.

I hope that this will help you out!

I have a 2003 Dodge Neon se there's a major oil leak between the engine and transmission how do I fix this

Check that the oil leak is not engine oil coming out before the bell housing ( sump gasket) If the oil is coming out of the bell housing inspection cover then it means box put and either flywheel off for a rear main seal or torque converter out for a seal in the box or converter.. If it is a sump or rear main seal check the engine oil level first and the PCV valve operation as excessive oil level and sump pressure will cause the engine side problems that you can fix without removing the box.

Leaking from the front of bellhouseing

Gday mate,geoff here, there are 3 things that can leak there, 1st is coolant as there should be a freeze plug at the back of each cylinder bank in there.
2nd engine oil as there is a seal on the crankshaft and a plug at the back of the Cam tunnel, mostly if its engine oil it will be the crank seal.
3rd is gear/transmission oil, front seal on the gearbox if that is the case, also make sure that the oil isn't coming from the top and leaking down to look like its the bell housing leaking, as the valley cover and rocker covers extend back to just above the bell housing, hope this helps, geoff.

Truck runs great @ 168K miles. No engine performance or power loss. But recently started leaking oil slowly from unknown location. Drips accumulate and appear below & back of engine by transmission...

Their is a front and rear oil seal on the oil pan itself..........If it is leaking by the bell housing then you will have to drop the oil pan and replace the rear oil seal and i would do the front one on the pan as well..........Hope this helps.

Engine oil leaking near sending unit. Replaced unit and oil still leaks. What could be the cause?

Look up overhead above the sending unit for any oil that maybe dripping from above,makeing you think it's the sending unit leaking. If not then you may use a little thread sealer to seal the leak. Also check to see if the sending unit is loose and the threads may not be the same as the old unit you removed (metric/standard/pipe) Hope this will help you.

Oil leaking from engine right at the top of the bell housing?

it sounds like your oil pressure sending unit has gone bad. It is on the top back of the eng. close to the fire wall. If you don't have a good tool to take it out you could use a plumbing stem puller. It worked great. proper size is 1 1/16
Good luck and hope this helps. When replacing the oil sensor, make sure you do not use and teflon tape or silicon. The sensor is tapered and need a good ground to the engine to get proper readings.
