My 80 series ( 1HDT engine ) is feeling sluggish when the turbo kicks in, there is oil leaking around the turbo and when it idles there is the blueish whitish smoke haze- not heavy but you can see it. I service the car every 4-5000 km and do look after it, but it just seems like it is underpowered at the moment. The fuel pump has been rebuilt twice in the past 2 years and i have also pulled the filters out of the tanks to clean.
When i bought the car the owners rebuilt the engine ( 80,000 km ago ) but didnt touch the turbo, not saying it is but wouldnt mind getting it checked i suppose
