    Head Gasket blown- when cold?

    2007 Cayman S with 66k miles. Fully dealer serviced, never tracked and used 3-4 times a week.
    I put it in the garage just after Christmas then we had a snowy spell (but no more than -2c) so it sat there for 10 days until I went to check on it. Started fine and I let it run for about 5 minutes before I locked it back up again- not ideal but it was still too snowy to drive.
    Another 10 days pass, the snow has gone and so I decide to take it for a drive.
    Turns over slowly, starts and fires on five cylinders. I let it run for a few minutes, no smoke or noises but can't get it to run on 6 and a CEL shows up.
    Locked it up and left it for two days.
    2 days later, go to start it and I get loads of white smoke (not steam) CEL and then after a minute the light on the water temp gauge starts flashing. Turned it off and got it recovered to the dealer.
    They are saying that it's a head gasket: cyl 2 to be precise.
    Can you blow a head gasket when the engine is cold? I've never heard of it before.

    I hope they tested the anti-freeze/coolant. Even -2C is still freezing. However, a cold start by itself (with no other issues) wouldn't blow a head gasket.

    Starting and running the engine for short periods has been know to cause a lot of white smoke on subsequent restarts. Usually from condensation or combustion byproduct that the engine/exhaust didn't get hot enough to evaporate. So the next start-up you see the cloud. However, that wouldn't throw any codes or cause "check engine" issues.

    Yes it was tested at the last service back in May last year. I specifically asked them to check it.

    It's all very odd.

    The dealership has contacted Porsche Germany. They are of the opinion that it will be the crankcases and they will pay 65% of the parts. I've authorised a strip down to find out exactly what has happened. More news on Monday.

    You should ask how they determined that it was a head gasket. Based on your description, I would first suspect a jammed injector. Also, you can usually see the effects of a blown headgasket right away by simply opening the coolant cap and looking for bubbling when you rev the engine.

    The dealer thinks it's a head gasket. They did a compression test and found that CYL 2 is pissing out antifreeze. Porsche Germany are really sure it's the crankcase.
    It all seems odd. I am waiting for the strip-down and then I'll be calling in to the dealer and will be asking to see the evidence of their diagnosis.

    That's too bad, but I'm still confused. How did Porsche Germany determine that the crankcase is the culprit?

    The dealer told them the symptoms over the phone.

    Yes, I know, incredible and odd!

    Anyway, I should know more on Monday.

    I need to investigate every possibility.

    Me thinks they have seen it before

    Maybe, but would a "broken" crankcase give the same symptoms as described in my first post?

    You either have a cracked head, cylinder or head gasket. Factory says cylinder.

    No, sorry. You said the car was cold and sat for a while and then had white smoke that was not coolant. If the gas got gummed up a bit, it could cause an injector to stick open a bit and dump fuel into a cylinder. You can make giant billowing clouds of smoke this way (my first car to ever break down on me did this back in the 90's).

    But if the dealer says the cylinder is filling with coolant, then your best case scenario is a blown head gasket. Worst case would be a cracked cylinder, and intermediate case would be cracked or warped head.

    I still don't know how a "cracked case" fits into this. If your case cracks, you'll have oil all over the garage floor, tons of black smoke, etc. Is it possible that the factory said "cracked cylinder" and the dealer translated that as "cracked case?"

    Factory was right.
    Large crack (as in- not hairline) in one cylinder (no. 2 I think?)
    Stripping it further to see if there's anything else damaged like pistons
    before they approach Porsche in hope of a contribution.

    Is this a common fault? Dealer says they've never seen or heard of one before?


    Any advice, anyone?

    If you believe Hartech (out of the UK), it is very, very common -- even inevitable -- and is due to a flawed design. I don't know about the inevitability, but of course it's a flawed design! Whoever heard of an engine cracking at just 66k miles on a 6-year-old car?!? We get this "excellence in engineering" BS about Porsche, but all of the signs point to the fact that their engine development teams are a tiny fraction of the size of engine teams at big companies like Nissan. When they make design mistakes, they are BIG mistakes, and they don't fix them for 8-10 years (IMSicon, for example). I love how Porsche nails the exterior style, the interior spartan-but-high-quality style, the steering, and the suspension; but other than sounding great, their street engines are $h!t.

    In my head, it seems like the cylinder scoring/cracking is much more common in Europe than in the US, but I've not seen statistics that confirm that notion. Regardless, statistics probably don't matter a whole lot to you at this point. Very sorry to hear about your engine woes!

    Why would it be more common in Europe!?

    Whilst these problems exist, like IMS, it's not that frequent.
