Thread: LT85 & LT230

Maggot, What was the verdict?

Came back from a trip and the gearbox started to get notchy on the changes. Pulled up in the driveway and took a look under to see a rather large amount of oil spew out of the bell housing.....

If the breather was blocked... Probably, yes. Either that or what ever route offered the path of least resistance.

Not sure on the Rangie but if either the gearbox or transfer case have blocked breathers one can pressurize and blow the seal to the other which causes either box to overflow oil. The excess oil will come out of the breather thats not blocked.Check the level of either, see wich one is low and which one is leaking this may be an indication. I know 75 series Landcruisers that this was the case. I placed a hose from the transfer case to the gear box on my 75 series to stop this from happening as well as cleaning the breathers. As I said not sure if you can do that on the Rangie or not.Hope this helps out??

Thanks

It dosen't happen at any other time?

I'm talking like 500ml!

Sounds about rite if the breathers block up the gearbox will presurise and push oil past the seals .....

yep it will, if the oil came out of the bell housing you could be in a spot of trouble, once blown out the seal leak forever... leave your bellhousing drainplug out and see what keeps coming out...

then goto super crap, grab 4 of those cheapyu fuel filters and then put them on the end of the breathers, no more clogged breathers. I also bet some extra hose and then push them back through one of the grommets to inside the dash behind the instrument binnicale.
