Diff oil leak

[GTROB]

Hey all

I've got a Oz Del R32 GTR and have been having alot of problem's with a oil leak on the front diff. I have replace the pinion seal and axel seal's and sealed the front cover, but it still seem's to be leaking oil. The leak looks to be coming from around the front cover. Does any one know if there was a batch of Porous diff housings or not.

Cheers.

Craig.

My only suggestion is to clean it down and re-inspect.

Have you checked the level of oil. Sometimes overfilling can cause leaks. What type of fluid is it that is leaking? how much? and how quickly?

[GTROB]

I am currently running a Castrol Synthetic gear oil in there. I have cleaned it down and inspected it a number of times now. The leak is only a very minor leak. BUT it is a oil leak and that's just not allowed.

[The Dan]

Does it actually appear to be coming through the metal?

If you have cleaned it down and inspected it a number of times you should be able to see the EXACT location of the leak. Maybe not. I know how hard they are to find sometimes.

[GTROB]

Yeah it's real hard to tell, as it is coming from the front of the diff around the front cover. I have checked to make sure the front cover and diff housing are flat and even machined a couple of thou off the front cover. I have even tried making a gasket for the cover and an number of different sealant's and still no joy.

[The Dan]

If it's not meant to have a gasket there, don't use one.

They are supposed to be sealant only. use 3 bond. Nothing even comes close.

Wait a day until it is set then fill the diff back up again.

You may have already done this but to tell the truth, there aren't really any other places that it can leak from. Unless there is a hairline crack in the housing somewhere that you can't see.
