Gearbox Pressure Build Up?

[SargeRX8]

Is that smurf blood shit like a green blue color? My car had that stuff in it. Ill try this amsoil stuff next with the nulon additive!

Common problem, just changed to the shockproof oil a couple of weeks ago and sure enough I have oil coming out of the breather, never had this issue until this oil went in.

Is there a solution to this issue other than changing the oil, seems like a waste of big dollars to dump it for a different brand.

Might try contacting Redline otherwise.

[joeyta22]

Would be interested to hear what redline have to say about it. By the sounds of it there is something within the oil itself which is causing it to froth up, only solution really is to dump it and get another oil.

[smithy85]

Email sent to Redline Oils, lets see what they say about this, if anything.

OH FOR F@CKS SAKE

i just put the stuff in! and now i need to change it out

[SiR_RB]

ive been running redline shockproof in my gtr for 1 year now and no problems at all !

must of been a bad batch somewhere

[R31 POWER]

Sounds very weird. 1 gallon went in the 33 about a month ago and it hasn't spat any out. Is there a batch number on the bottles??

[smithy85]

The reply from Redline gave me links to these two:

Bulletin115 Shockproof Climbing.pdf

Bulletin116 Shockproof myths.pdf

Very interesting reading and explanations.

So essentially - extend the breather hose or just deal with it, lol.

That is FALSE - Do not think that extending your breathers will fix the problem.

We extended them higher and longer. It still made it all the way up and 1L would come out on cruise but none on the race track. It was only ever on the way to the race track we would lose that much. It would still lose it in small amounts on the track but not even a fraction in comparison.

They are just avoiding the problem. We moved to a better oil, we no longer have this problem

what oil u using now?

[joeyta22]

Hmmm interesting. So what happens when it has "climbed" all the oil out of the box? You have to keep refilling it all the time? Sounds shifty, im still running the oil previously mentioned and have had not 1 drip come out of the breather that i can see.

We use Royal Purple 75w85 in all the street car stuff and Royal Purple 85w140 in the race stuff

Or Motul Gear Competition on request

Yes, we had to keep pumping it back in. Even when it was 1L down, it would still pump it out up 3M of hose that was half a meter higher than the factory point and spit another half litre out into our bottle

im assuming this is in reference to Max-Gear which is suitable for diffs (75W-90, 75W-140, 85W-140 1quart bottles)

for gearbox i only see Synchromax listed but no info on the weights available

also cant find anything on Max-Gear being suitable for LSD

[The Dan]

Syncromax is different

Synchromax® is recommended for manual transmissions that specify an automatic transmission fluid or motor oil. It is also ideal for 4x4 transfer cases and / or 2-cycle and 4-cycle motorcycle gear boxes.

And yes - Max Gear is suitable for LSD

[GTR_JOEY]

Righto,

fears are confirmed.. THERE IS f**kIN OIL EVERY!!!, seems to only happen on longer trips EG 100km plus.. anyway

the redline light shock proof is absolutly pissing out the breather, not going to risk spending that much money again. Dont really care if it was a bad batch. Going to change to something else..

probably RP or Motul like Elite has recommended

cheers

[Ryan1200]

Sorry not an easy fix I added a 2nd breather to the inspection plate on the top of the gearbox never seen another drop of smurfs blood from either breather again.

[Daz]

Yep I got the same problem, thought I was missing a hose up top. Will change oil never to go back to redline
