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.

      I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
