Hi my name is frik I have a oil leak on front and

There are seals on the front and rear of the transmission. If the clutch wasn't covered in engine oil, then replacing the crankshaft seal wasn't necessary. Reseal the transmission.

Being that we have the Nissan Pathfinder (closest vehicle here), which like my 2001 Nissan Xterra uses Nissan Matic-D, you can use a Nissan Matic-D (or J), or a compatible fluid such as Valvoline MaxLife or Castrol TransMax Import Multi-Vehicle

could be your gearbox seals.Check if the front one is gearbox oil or engine oil.If it is engine oil then could be your rocker cover seals..oil from the top travelling down,sump gaskits or crank shaft seals.The direction of travels pushes oil towards the rear and sometimes we think that the leak is on the rear somewhere whereas it could be in the front.

If the front differential is covered with oil, chances are that the leak is from the pinion seal on the diff itself or from an engine leak. check all the fluids and find what is low and clean off all the residue there so you can find the source. Since the t case is behind the diff, and the air flow is towards the rear (unless you drive backwards all day long) any leaks would tend to blow towards the back, not towards the front.Once you find the actual leak source, someone here can help advise you on how the repair can be made.

Bad leak at the rear main wont give you low oil engine pressure ,its sign that the main bearings are worn or the thrusts .
Check the crank pulley end float and lift first but the main can be done in place drop the gearbox and flywheel.

Hi,

That engine will leak oil from

- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)

YOU carnt have a transmission oil leak from the front axle on a Falcon as they are Rear wheel drive but could be the hose going to the radiator over the front end leaking But the rear end of G/Box should be only the OIL SEAL.

Hi,
The main reason for the oil leakage is most probably due to the rear crankshaft seal.
First thing to do is check the engine breather is clear. You can clean it with isopropyl alcohol and dry with a heat gun.

Thank you for contacting www.Fixya.com

I assume its a standard transmission.
Should be a threaded plug on the top of trans , or 1/2 way up on the side.
If auto trans , add fluid through dipstick tube.

hi from uk if your oil ? leak is from rear of engine area ? but you say oil level in engine is ok? and not needed to top up ? then i would check the gearbox/transmission oil level? for any loss? asap it may be your leak is coming from g/box/transmission front seal ? but either way gearbox will have to come out do be able to replace both rear engine crank seal and g/box front seal at the same time ? hope this helps you don;t delay in topping oil level in trans ?
