Been awhile since anything happened here. A couple of weeks ago i changed the PCV.
The car smokes white. it doesn't take coolant and oil is not milky. What i think it might be is either PCV (just changed) or valve stem seals or turbo.
Today i pulled of the turbo. i bought a genuine mitsubishi rebuild kit for my little 15G turbo and i took everything apart today. Tomorrow i will reassemble again with new fresh parts. Thankfully i found this guide on the interweb:
http://www.volvohowto.com/how-to-refurbish-and-replace-a-turbo-on-volvo-850-s70-v70-or-c70/
I thought i wanted to get the car running ok before i start throwing money at suspension, brakes etc.
