I have a skoda octavia that came in suffering with lack of power and smoking.
there was oil in the mouth of the turbo
I took the turbo off to see if there was any obvious signs of damage, and yes there was. the shaft had broken and the propeler on the manifold was broke of and stuck in the turbo.
What I am asking is, is any reasons this could happen, is there a problem before the problem, so when i replace the turbo it doesn't happen again. Is it common.
There is oil in all the intercooler pipes and emulsified oil inside the intercooler, like scum. Whats the best way to clean out intercooler and pipes.
