GUYS DON'T scare this guy and tell him his piston rings are fried , he said it was on there for one mile , don't jump to the worst conclusions right away !
milkman : I also have a crappy turbonetics turbo that blows oil through the seals. First like said above , check the return line and feed line sizes and if these are correct then its your turbo . When I idle it blows lots of oil , when I turn the car on after letting it idle it'll also throw oil out of the exhaust.
As a matter of fact I just took off the turbo yesterday to figure out what to do next. The turbo when inspected looks fine , he turbine housing and full rear assembly must be removed to see the where the oil leaks and the buildup . Oil leakege throught the turbine housing has been a problem with turbochargers forever . I've checked my lines and they are of good sizes . My turbo is freshly rebuilt too. Also worth mentioning , turbonetics has a new seal design posted on their website called the "staggered seal" design that they say will stop this problem .
BTW do you have a water cooled turbo ? water cooled ones tend to burn oil through the seals more often.
