I rang Garrett about my turbo that was there first reponce needs de-sooting , woo back mine is 28 years old I just want to know if there are parts available , leaks on the waste gate shaft from wear .
I will ring Garrett Turbos and see what I have to do to get it sorted...Never heard of de-coked but they are the experts.
I found the diff had LSD oil in it which apparently shouldn't as the LSD has been removed when the difflockers we installed. I have replaced all the driveline oils with Gulf Western 85-140 and still have the oil coming back through the air locker blue line. Also noticed with the new oil that changing gears is a bit sticky so hoping that will correct itself after a short drive. Feels a lot quieter for the 2km's drive around the block I did to check for leaks.
The other issue I have is that the gearbox jumps out of 5th and 4th gear when decelerating on a downhill slope. I took it into Currumbin Transmissions and they said that the only way that could happen if if someone has done a lot of towing in 5th gear or maybe the selector gate has somehow warn, but also said that these boxes are bullet-proof and were very surprised at it doing that. Asking a few other people have found out it may do this for the next 500,000km's so if you can put up with it leave it as it is...hopefully that is correct.
Great to hear QueenslandChris.
I also thought the Air Locker Services and Parts Manual might help you out as it lists recommended oils to use. It can be found here http://www.arb.com.au/media/products/air-lockers/Air_Locker_SP_Manual.pdf
