im trying to find clues of a bad turbo. im having a couple issues and im wondering if its a bad turbo or not. a little bit of smoke coming from under the intake somewhere, alot of white smokes coming from exhaust, vac. idle is at 10 instead of 20...so im just trying to find out how i would know if a turbo was bad, or what these problems could be from. thanks

 

None of the problems you listed would necessarily indicate a bad turbo. More likely leaky gaskets or a bad engine.

 

first i'd check where your vacuum leak is coming from, cause that's definitely low. the black smoke could be oil from something else other than the turbo.. but it doesn't rule out a bad turbo

 

He said white smoke, so I was thinking cold air condensation or an internal engine coolant leak, but not a turbo oil leak.

 

opps thanks for the correction.. it's late and i'm tired haha

sorry yes white smoke would lead me to believe coolant also, does it smell sweet?

 

yea i have no doubt in my mind it could be coolant cuz thats been the main problem with my 7...it also smells very strong of oil...how would i check/fix the internal coolant leak and how do i find out where the vac leak is?
