a few days ago during that vicious cold snap, i started up my car in the afternoon; it had been plugged in all night. Fired it up, let it idle for a few minutes, and headed off down 23rd ave.
Then i started to notice a haze behind me, as soon as i stopped to wait for a left hand turn onto rabbit hill road.
the haze turned to a thick whitish-blue smokescreen, obscuring the cars behind me, i saw it coming out a bit under the hood, and then through my dash vents. coughing, i rolled the windows down, and cruised home.
i'd not spooled up the turbo yet.
call mechanic, tell him i think i blew the seals or something, he advised me to try and get there on what oil i had left. Started it up in the driveway, less smoke, but i could still smell the burning scent.
As i was driving, it seemed to be ok. And when I got to the garage, nothing was wrong.
DIAGNOSIS
condensation in one of the feed/drain lines for the turbo had frozen the passage, meaning oil could not exit the turbo, or circulate out.
So the oil built up inside until it squeezed past the seals and into the exhaust/intake blades, where it was burnt and passed out through the exhaust
a few days later and everything is as it was before the incident.
this a common thing in really cold weather? Or a freak occurance?
Wonder if new braided lines have become more of a priority... |

| That's crazy if you oil return had enough moisture in it to freeze. How big is your return line? I'm thinking it should be at least 1/2" id. Is there white stuff on the end of your oil dipstick? |

| Sorry, I just re-red and you said "feed/drain lines", thats still crazy. |

I don't really see how SS lines would make any difference.
If you don't drive your vehicle long enough to get the temperature up to full operating levels and sustain it for a while, condensation will build up in your oil. You see it quite often. Someone drives their vehicle around the city most of the time and their oil level stays nice and high. Eventually they take a run on the highway, check the oil after a few hours of driving and it's down a litre or two. This is just that condensation evaporating; the vehicle had been burning small amounts of oil all along.
When was the last time that you have done an oil change before this happened? |
