Gtr Rear Diff Oil Leak.

[markimak]

hi guys.

i changed my Rear diff oil with castrol LSD oil (from a barrel used by toyota dealership workshops) around 4-5mnths ago. its all fine. the rear LSD locks up fine but ive noticed that after i run it hard lock the diff up and park afterwards ther was a bit of oil around the LH side of the diff housing. the side with the filler hole plug and breather. Not dripping more like residue but enough to form.

im thinking.

1). its from the diff breather valve ontop. looks to be around that area.

2). bad seal on that side of the diff. same area.

3). spilt oil when the oil was changed.

it had absolutly no leaks and noticed it only after the oil change.

im guessing that when i drive it hard, the oil thins and comes out of the breather on top. hilux and hiace sealed diffs do the same.

any other ideas or suggestions.

thanks

mark.

poor seal. most 32 GTR diffs I've bothered to look at have a slightly leaky (better described as weepy) rear diff.

2 options.

either just ignore it but check it once in a while to make sure it's not getting worse

or whip the cover off and try and get it sealed up nicely.

thanks bear baron

but it didnt have a poor seal before the oil change. i mean completly spotless. but only now. is the oil to thin or thinning too much?

mine does that.

it pises out the breather on the top when driven had. like badly.

you need to put a longish hose on it so it raises it up abit.

later ones had a small checkvalve in them. to keep them shut longer.

so its absolutly normal.. fine.. good i was a little worried. im guessing its just the oil getting thin when its warmed and come out of the breather.

does the gearbox have a breather too or the transfer case?

Checked mine today....i saw it was weeping and topped up.

It took about 50ml at most.

Should have completely changed it but ran out of red-line shock proof.

Is this the oil for this? It has differential oil market on the container.

I changed the gear box oil today....what a difference.
