I slapped my KKR480 turbo on a while back and ever since its been blowing oil smoke... :'(

Obviously leaking down the shaft because sleve bearing sucks.

It wasn't really blowing much smoke then yesterday I put some new oil in it, basicly just to flash it out, some crappy oil thats like $18 for 4L. I was planning to run this for a few 100km then put some decent stuff in it. Any way now the car is undrivable due to the ammount of smoke it bellows.

Before I go an buy my decent oil what do you guys thing I should get, I know that the type of oil does make a difference and the oil seals in my turbo fine its just that its a crappy sleve bearing and rather than having an oil seal it basicly just has a metal C clip and sits on the shaft and oil leaks through it easy as.

My oil drain is nice and big and free flowing but yeah I basicly want this thing to be drive able so I can save up for a couple of months and get a Garret GT40R. So any Idea's on oil, I heard that it will blow heaps of smoke on synthetic because its such a thin oil but yeah what do you think? any Ideas? I am tempted to hit my oil line with a hammer and let the turbo have a slow death from not much oil, atleast I will get my 3 months life out of it... maybe... so I can get a Garret GT40. Nice waste of $950 I guess.

because of the journal bearing you need to feed more oil to it (which is why you need to make the oil feed line bigger to these types of turbos).

look out for a blocked oil drain pipe, blocked PCV, blocked breathers etc.

is there any oil in your cooler pipes? catch can? intake?

perhaps this hasn't been done, and the turbo has now shit itself because of insufficient oil.

there's nothing wrong with a sleeve bearing turbo, if you treat it right. My R31 turbo stood up to 14psi and no BOV for 3 years, plus whatever the previous owner threw at it.

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
