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.

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.

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

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.

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

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

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

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

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

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
