I've got a 2007 presara. I missed a couple of services before last year(2011-2012). since the beginning of 2013, the car started make blue/white smoke at cold starts. I went to ultra tune for service, they changed oil etc. the smoke went away but came back after a couple of months or so (less then before). I went back to ultratune, they said the engine had no problem. However, it gradully got worse. We drove to red hills (about 200KM in total) during new year. At the end. it became really bad. I went to service at a toyota dealer last thursday, the guy there suggested a engine flush as he could see so much sludge from the engine oil filling hole. after the flush, the car was fine, no smoke, engine oil was so clear; Although I still could see some sludge in the engine around the hole. I called the guy, he said those residual sludge would come off after a couple weeks. But after I drove a 20KM trip on last Saturday, the smoke was back again. I opened the oil cap, noticed the residual sludge had almost all gone, and oil had more colour (still good light brownish). I thought the smoke might be caused by some sludge left in the exhaust or something like that. After a day or two, the smoke had gone again. However, I had another 20KM drive yesterday, guess what, the smoke is back again. And this morning, it seemed a little better again.
I know there is something really bad with the engine. but just want to know what is it. Would anyone know why the engine doesn't like long drive anymore?
Should I get it fixed or simply replace the engine?

Hi,
I've got a 2007 presara. I missed a couple of services
before last year(2011-2012). since the beginning of 2013, the car started make
blue/white smoke at cold starts. I went to ultra tune for service, they changed
oil etc. the smoke went away but came back after a couple of months or so (less
then before). I went back to ultratune, they said the engine had no problem.
However, it gradully got worse. We drove to red hills (about 200KM in total)
during new year. At the end. it became really bad. I went to service at a
toyota dealer last thursday, the guy there suggested a engine flush as he could
see so much sludge from the engine oil filling hole. after the flush, the car
was fine, no smoke, engine oil was so clear; Although I still could see some
sludge in the engine around the hole. I called the guy, he said those residual
sludge would come off after a couple weeks. But after I drove a 20KM trip on
last Saturday, the smoke was back again. I opened the oil cap, noticed the residual
sludge had almost all gone, and oil had more colour (still good light
brownish). I thought the smoke might be caused by some sludge left in the
exhaust or something like that. After a day or two, the smoke had gone again.
However, I had another 20KM drive yesterday, guess what, the smoke is back
again. And this morning, it seemed a little better again.
I know there is something really bad with the engine. but just want to know what is it. Would anyone know why the engine doesn't like long drive anymore?
Should I get it fixed or simply replace the engine?
Thanks in advance for your help.
