Hi evereyone. Is there anyone out there who can help me? I have an A4 B8 TDi 170 (CAHA). Had the car for just over a year, doing the usual maintenance etc. No real issues.
Couple of weeks ago I was driving the car (About 10 minutes from cold), when suddenly there was a lot of what I'm sure was blue smoke coming from the exhaust. I pulled into a layby and got out. Even at engine idle there was smoke from the exhaust. Switched off and went and had a coffee considering the options for the car... Nose dive into a quarry, swim in the lake, or even leaving the car on the drive to rot away to nothing. Drove home... After searching the internet, I find that there is very little info on this. One theory is the PCV, crankcase ventilation. So i went out to the car, started it up (Cold). Hey presto, no smoke! Took the oil filler cap off and sure enough it's chuffing out crankcase pressure. Took the pipe off that goes from the valve cover breather to the air filter/turbo and lo and behold there's oil in there. It's obviously finding its way into the turbo. I find it strange that from cold there's no smoke, but after a little while it smokes. I'm assuming that it takes a clittle while for the pressure to build up and then force oil into the breather outlet.
So here's the thing. Would I be wise to invest in a new cam/head cover which comes complete with new breather etc? Or am I wasting my time and scrap the car? Other than this, there is no loss of power, engine runs smoothly and no noises not previously heard.
Anyone out there had a similar experience who can shed some light on this issue?
Thanks, and have a great day!
