Video - occasional white smoke on startup for a second or two


Recommended Posts

Hello,

 

Please have a look at this video:

https://www.youtube.com/watch?v=4WD1b8naXgo

 

On my car it only lasts for a couple seconds. This occurs perhaps 1 per 20 startups and I have a strong feeling that only after cold nights or during cold mornings (defining cold here as 40-50F). I drive this car on a daily basis.

 

Would you consider this normal behaviour?

 

Many are posting similar questions like mine but without a video it is hard to judge if it is fine and occurs because some oil flows past rings to combustion chamber due to Boxster engine layout. Also some are talking of white, some grayish and some blue smoke :-)

 

My car is 996, 2004, 3.6L, around 90k miles. AOS, plugs, coils are brand new. Both exhaust and cats look like brand new when borescoping. Leak down test >96/100PSI each cylinder, does not consume oil or coolant. Oil level is very close to maximum level, perhaps a tad lower than maximum. Using Motul X-Cess 8100 5w40. 

 

 

Thank you!

Mine is a 02, 3.6. I get smoke on start up like that every second week or so. My smoke is blue though and I burn oil like mad so I believe my issue is ring/cylinder related.

If your not burning any oil and the car is running fine, I wouldn't worry too much about it.

I would not be overly concerned.  Because of the horizontally opposed design of these engines, they occasionally do this.

      Can the 2001 behind the dash wire harness work with the 2003 harnesses including 3.6L engine,  engine harness,  rear harness, dme 7.8, immobilizer,  etc
       
      This is a swapped 3.6 car that was functioning properly in an earlier 2001 race car. Had to Retub the car and move all the harnesses to donor 2001 chassis. Moved everything except the wire harness behind the dash. 
      The car starts and functions except water temp gauge on the 2003 cluster connected to the 2001 wire harness behind the dash.  Also durametric recognized the cluster as an earlier cluster and not the k21 (3.6l) cluster. 
      Any help will be appreciated.

      2002 C2, 95k miles, original exhaust and O2 sensors.
       
      A few months back the CEL went on, Durametric says P0420: Porsche fault code 40 - Cat. conv. efficiency bank 1. CEL has stayed on so I investigated further. Pre- and post-cat O2 sensor voltages shown in attached charts, upper chart for Bank 1 and the lower for Bank 2. Warmed up the system at idle, then throttled up to 2.5 - 3k three times, two short, one long, during which time all sensors went near zero.
       
      It looks like Bank 1 (upper chart) post-cat sensor is showing a problem while Bank 2 (lower) looks fine. (I started capturing Bank 2 after Bank 1) Also for a few years there has been a little rattling on the driver's side exhaust which I've suspected is a failing cat, but the exhaust system has not been recording any faults until now.
       
      After having read a few related threads, it seems fairly certain that the Bank 1 cat is failing, perhaps with a loose element that reduced cat performance after the third throttle bump in the charts below. I'm leaning that way because it appears the sensors are all reporting data at about the same rate, oscillating when expected, except for post-cat Bank 1's sensor which begins the capture looking like it is largely reporting correctly but ends with oscillations that shouldn't be there.
       
      There has been no perceptible change in performance, and I have over a year until the next smog inspection, so there's time.
       
      Does this information indicate a pretty strong likelihood of a failing Bank 1 cat? Or are there additional diagnostic steps I should take to eliminate other causes?

      1999 Carrera4. 5 years I have chased this intermittent problem. Sometimes the car refuses to start. Starter will not turn over. All maintainance has been done at a dealer service center. They say they've never seen this issue before. It's not DME they say. Every component from entire key system to the starter, as part of the security system/start permission, has been replaced. Car can go for months with no issue, start every time, then it's like a gremlin grabs it and it will not start. No error code(s) reported. Everything appears normal and proper with dash lights. Might be a minute, an hour, a day, a week... and it starts. You never know if it will start or not. 

      Possible weak point in the wiring? Software issue? I'm flying blind on this.

      Has anyone experienced anything like this?

      I have a 2003 996 carrera cabrio. Recently it has developed a rattle or possibly a warning buzzer at exactly 60 mph. Could this be related to the limiter setting? Any help would be greatly appreciated. Thank you in advance

      My 1999 911 Carrera started smoking at a streetlight. Very smelly blue smoke was coming from under the engine cover. I pulled over and popped the cover. Blue smoke was coming from somewhere under the engine (not the exhaust). The engine stopped very suddenly.
       
      We don't have a local Porsche dealer, but the Subaru dealer owns a bunch of 911s and he has a couple Porsche mechanics. I had it towed there.
       
      The C1 fuse ("Engine Electronics") was blown. They replaced it, but as soon as they turned the key, the "cam adjuster wiring harness" (I do not know what this is) began to smoke, and the fuse blew again.
       
      They disconnected the cam adjuster wiring harness (I don't know what this means, and neither did the service advisor), and the fuse stayed intact, and they got the car started. They were able to drive it out to the parking lot with no problems.
       
      They said I need a new cam adjuster wiring harness (again, no idea what this is), and this would require an engine out repair, which they could not do. They estimated this work at $5,000 to $6,000.

      Additionally, they did not know how drivable the car was with a disconnected cam adjuster wiring harness.
       
      So ... how bad is this?  (Service report image attached.)
