[Gear Box Breather]

A Guy here in sweden works with renovate skyline engines and gearboxes. He hates the redline oil and says it damages the gearboxes. The picture is of the redline oil

the other picture is the oil he recomended and the one i have.

Mine worked a couple of years with redlige. But after one change the problems came. Changed again to a nej redline and the problem remained. Now i drive with mobil1 and havent had a single problem ?? First i bought a cheaper oil and drove a couple of miles then changed to the mobil1 just to clean the inside and get rid of the redline oil

did anyone try to change ta another brand? and did that help?
i have the same problem, had a bunch of other brands before then after one change it started to spit out of the breather.

[R33 Gts-t Rb25 Gearbox]

Now im bumping this thread a bit.

I have the same problem as murph on my Rb25det

my gearbox throws up oil from the breather, i have also redline's shockproof lighweigt oil.

it startet last year and it keept throw up even when i changed the oil so it maybe was a bad batch.

and for this year i bought a second gearbox and the redline oil, keeps throwing up oil from the breather

What is the problem?? Is it the oil,? it must be becaus the guy i bought the second gearbox from had no leaks.
