smelt sumthing funny from the engine a few days ago. just after i changed my thermostat. at normal speed it wasnt there but as i came to idle at the lights i could smell oil burning . i found the source of the smell. from sum where oil was leaking on the turbo compressor back housing. i degreased my engine and drove it 4 a cupl days and voila the smell was back. i looked at the turbo again and where there was no oil was now dark with oil. i applied pressure on the oil feed bolt but there was no play so it wasnt loose. i looked at the banjo bolt towards the back of the turbo and there was nothing. i did notice that the compressor backing housing was seeping a tiny amount of what seemed was oil mixed with carbon. my turbo howls on the odd accossion on spool up and i think the unit might be tired. any suggestions or perhaps any probs of similar nature would b good info 4 me. short of replacing i may have 3 have it serviced:(

Try tightening all of your turbo hose clamps. A while back I found a dribble of oil leaking from the turbo-to-intercooler hose connection.

Also, if you haven't done it, go through and tighten all of the turbo related hose clamps. I found I was losing quite a bit of pressure due to loose connections.

If it is not the connections it sounds like rebuild time. If you do a search here or at probetalk there are plenty of people or places that do it.

Umm you shouldnt have oil dribbling from there.

thanx again fellas! i had a quick search again with my mate at his rally cross workshop. we got it up on the hoist and its definitely a tired turbo. he could fix it 4 me within the day but he suggested i try 2 nurse it a little by almost eliminating boost and keeping the revs low and 2 top the oil up every 2 days or so. he suggest i save the extra cash to get a garret ball bearing or even just hi-flow the re built version. the sevice of seals and so on is round AUD$450-$500. the rebuild is round $900-$1200!!! the garret ball bearing turbo(new)is $1800!!!. at this stage i am thinking a rebuild at the most extreme but the garret seems a luxury especially as i am getting rid of the car in about 3 months time...tho theres no reason for me to botch up the job. luckily my mate is gonna wave the labour fee.any other suggestions would b very much appreciated.

option

You could always buy a used one at a local salvage yard, since you dont plan on keeping it much longer. I got one to put in while the original got rebuilt, only cost me $100 and was in realy good condition. Just call around. Later.
