    Blue Smoke from exhaust on "cold starts"

    Greetings,

    I have recently noticed that when I start my car on a ?cold start? blue smoke, comes out of the exhaust. The blue smoke is brief and lasts no more than 2 or 3 seconds.

    I understand that blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. However, blue smoke occurs in older or higher mileage vehicles when seals, gaskets, and O-rings designed to keep the engine oil from entering the cylinder begin to wear.

    Here are some background facts on the history of my 2006 Mustang GT that might help diagnose the problem:

    - Currently has 11,061 kilometers.
    - Car is not my daily driver. It is driven primarily on weekends.
    - 4 oil changes to date at 2,500 KM, 5,000 KM (by dealer), 7,500 KM, and 11,000 KM (by dealer).
    - Car was stored from November 06 to May 07 in an unheated garage
    - Oil change performed prior to storage
    - Car was parked during storage period and never moved
    - Car was started once a month during storage
    - Monthly procedure included normal idle for 10 minutes and high idle for 20 minutes at 2,000 RPM in neutral
    - Oil change performed immediately after storage
    - Blue smoke noticed after storage period
    - Not sure what brand of oil Ford uses for their oil changes but I use Quakerstate
    - Recommended oil is 5W-20 for the 4.6L V8.
    - I have be using 5W-30 on my oil changes with the understanding that I would be getting less engine component wear with a slight thicker oil.

    I have just posted a message on Ford?s website (omitting my storage and oil change procedures) regarding this issue. I will update this message when Ford replies.

    The dealer changed the oil today as part of the car?s regular maintenance. The mechanic at the dealership confirmed that there have be no issues with blue smoke on these types of engines. In addition, Ford has not issued any bulletins regarding this problem.

    Now that the engine oil is been changed back to 5W-20 I will monitor this problem. Perhaps this engine is sensitive to 5W-30.

    I would appreciate any criticisms or arguments in my method of storage or the type of oil I have been using that may be the causing of this problem. I would also be interested in anyone who may also be experiencing this type of problem on a new engine.

    Thanking you in advance,

    Raymond

    There could be 10 cars parked outside the dealer service, all burning oil on startup, and the dealer would still tell you that its the first time they have ever heard of it. I dont understand why they (all dealers/manufacturers) have to feel the need to bullshit people. I wish you luck, ive heard of this issue a couple times now, and all i can say is id be PISSED if my new...what, 40,000 dollar (all said and done) Deuce was huffin blue like an ol chev every time i started it up.
    Hound Ford, and try not to settle for some BS excuse.

    Ray, don't worry. Blue smoke on cold start-up is perfectly normal. Even my '05 does it in the mornings when I fire her up to go to work. If it was serious, you would get a check engine dummy light to let you know. Now, if you notice blue smoke while accelerating on the roads, then you have something to worry about. BTW, try switching to a major brand 5W 20 full synthetic (I've used Castrol Syntec in every Mustang I owned). Conventional oil is crap.

    are any of these cars actually using oil? maybe ford will release a new cal. are your cars up to date with the latest cal? go to motorcraftservice.com to find out the latest cal, not that you will likely be able to find out if your car has it already. just interesting stuff.

    I'm not personally real keen on starting a stored car once a month. If you don't start it every few days, I think you are better off to just have one after storage start up in the spring. If it doesn't use any oil though, I don't think I would get too worried about it.

    I didn't notice any blue smoke on startup with my car in the cold weather...my car initially had just 5w20 Motorcraft oil in it, but after it had 25K on it, I switched to FULL synthetic 5w20 Motorcraft, and the car seems to like it. I'm going to use that until I can find a local source for royal purple...

    Hope you have better luck with your car in the future!

    Went through basically the same thing Raymond with the wife's new 04 mustang. Same idea, different platform. After the first year of storage, I noticed 4 big spots of oil on my garage floor. Car had 3000 kms. on it. The oil was dripping from the back end of the engine. I took the car back to the dealership and told them I thought it was the rear main seal. The service manager told me I was crazy.

    Eventually; They had to put purple dye in with the oil to find out where it was leaking. MORONS. After my second trip back with the car, they finally found the problem. GUESS WHAT??? Was'nt so crazy after all. Rear main seal was gone. The look on his face was priceless! Got it fixed.

    The Next spring with 8000 kms, there is oil on the floor again. Take the car back once more. This time the valve pan gaskets are gone. Don't have them in stock. Finally, they come in and we get that fixed.

    Does'nt end there. A few months later, I notice oil on the floor yet once again. This time the intake manifold gaskets are gone. This is a brand new car!!! As of now the car has 18000 kms. on it and is finally leak free. This is just on the mustang.

    In 2001 I bought a new Ford Ranger. You would fall off your chair if I told you all the problems I had with that. Tailgate falling off twice, brakes, panels out of alignment, etc. Got it all straightened out in the end, after sitting down with the owner of the dealership; but 3/4 of the mileage on my truck now was from running it back to get the damn thing fixed. Both vehicles work like a top now, and I don't have any problems. Although they are trying to lure me back to their dealership, I have moved on and now deal with another one. They lost my business for good. I have spoken to Ford of Canada about it also. My advice to you is this:

    Don't take NO for an answer. Until your satisfied go back to the dealer where you bought the car. Tell them you will be back every day until the car is fixed properly. If you have to, go see the dealership owner. If he won't give you any satisfaction, go to another dealership. Your new car should not be puffing any blue smoke. Period.

    Back in the early 70's I had a new GM product that I had a problem with. Bought a new 72 Nova 350 4 speed. Brought the car home on a Fri night. Sat morning it was full of water. The dealership did'nt seem too interested in fixing it until I stopped paying for it. Then the big wigs from GM paid me a personal visit, wanted to know where their money was (payment) for the car. I told them when the car was fixed properly they would get their money and not until. Talk about service after that! Those boys at that dealership done everything but kiss my butt after that. You gotta get tough with these people man.

    the problem is the valve stem seals , that the "blue smoke" in the moring. ford should fix this under warrenty . blue smoke IS NOT NORMAL. anyone that tells you its normal should have thier heads examined.

    My experiences of dealing with the dealers falls on deaf ears. Go directly to Ford Canada and don't just make a phone call. That is what they want you to do, get in touch with Ford Canada Ombusdman and write a letter explaining your concern. If there still isn't any resolution, write another letter directly to the President of Ford Canada, you may laugh at this, but as soon as a Director/President of a corporation receives a letter, they become personally involved. You just can't be polite with some people!!!

    I have an 05 with nearly 40,000km.
    The car is not my daily driver and when it is driven it is driven hard.
    I change the oil every 5,000km and I use Mobil1 5W20 since 9,000km.
    Before that I was running the conventional oil with 3,000km change intervals.

    Mine has done this once in a while since new.
    When I will notice it the most is if I start the car and back it out of the garage and shut it off immediately.
    On the restart it will make a puff of smoke.
    What I believe this is is the oil from the PCV system which coats the inside of the intake especially near the throttle body.
    If you remove the throttle body you will notice a generous coating of oil inside the manifold.
    This comes from the drivers side valve cover.
    Do a search on other mustang forums and you will see that many are plumbing a Stefs oil separator in series with the PCV.

    I have been running mine with a Saleen S/C @ 12 psi (500rwhp) for the last 12 months without issue so I wouldn't believe that this is a major issue.

    I found this to and made my own separator catches about a tablespoon a week.
