    This is a first for me. Look at these extenders. I have never seen anything like this. Hopefully the engine is ok. Long story short. I just got this car and it was completely misrepresented. Believe it or not I was told it has never overheated or run hot. Not worth going into all the details but it must have really been overheated.

    I suspect they were made in China. ;)

    Seriously, I have never seen or heard of that before.

    They were actually fairly new. The engine was overheated and it got so hot it melted the extenders. I didn't overheat it. This was what I found when working on it.

    Ouch!! Yeah, not good! :(:(

    I have seen them melted many times before, but not on a Ferrari. :):)

    Have you already replaced them with new ones?? Does the engine start and run alright? :):)

    Do you think there is any engine damage?? :eek::eek:

    Perhaps you should do a compression and leak down test mate? Do a "sniffer" test also to see if those headgaskets are not leaking. :):)

    Common.

    I have seen them in hardened puddles in the bottom of the spark plug well.

    Often melts the plastic piece off the thermostat too.

    Very unusual for it to cause engine damage on the V8's. Ferrari uses a very high quality alloy, good head gaskets and the heads are very well attached.

    Brian is 100% correct. Brian and I spoke on the phone today about this. He told me to check the T-stat and sure enough it was melted also. I never would have thought to check that. It was really nice of Brian to take time out of his day to talk to me about it.
    Honestly, I just got the car. It was completely misrepresented so I started working on it. I am going to button it up and see how it does. All extenders replaced, new t-stat.

    It got so hot the tensioner bearings lost their grease. I replaced the t-belts and bearings.

    I looked at the headgaskets where they meet the block to look for any seepage and I didn't see any.

    Like I said I have owned many 308s and never seen or heard of anything like this.

    It was a relief to hear that it most likely won't cause damage to the headgaskets. I wonder if that kind of heat can harm the rings or valves though.

    Yup.
    Age has little to do with it, some of these are a few weeks old. Engine turned out to run just fine but now I have to get the rest of the plastic out of the well. Look at the corners of the cam covers and see if the gasket has pushed out. Often when they get this hot you will see the ends sticking outwards.

    Dave do you mean the headgasket pushing out or the valve cover gaskets? If the headgasket is pushing out some does this mean it is gone and needs replacement.

    Nope, just the cam cover gaskets. Look at the very corners where they meet the cam seal housings. Nice photo! Doesnt that chap your backside?!

    Private sale or dealer?

    OK I will do that. Will they leak oil once pushed out. So far the cams seals look great but I will check out the valve covers.

    Here is a pic of the engine. Whoever worked on it before put yellow paint on everything they worked on and they worked on a lot. There is yellow paint everywhere.

    The car at my end is doing just fine but leaks a little in the corners so it will get new gaskets. Runs nicely otherwise and seems to hold pressure in the cooling system as did those that went here before it. This would be a great time to be grateful there is 9 qts. of oil in that engine. Time to change it out now.

    I made sure I drained the oil today. Can't be good for the engines but it sounds like they are tough enough to keep going afterwards.

    Lots of little things Ferrari doesn't do well but they build a tough motor.

    John Cameron Swayze would have approved.

    Brian said it all. They take some damn hard knocks and keep going.

    I got it from a dealer in NJ. They seemed to have decent comments about them on this site but I certainly wouldn't recommend them. I am have put many calls in to them today and have yet to hear back from them.

    Strange enough I have heard many tales of melting extenders. The PO of my car spoke about it as well, and the tell-tale was a ticking sound of the spark jumping, so maybe they don't melt as much as that they burn.

    Someone suggested the extender of one of the Merc 123-series works well: a lot less expensive as well.

    Could it have something to do with water in the tunnels after washing? I always pull a piece of plastic over the engine and never had an issue.
