Cracks in fan housing

    Hello,


    I need your opinion. The fan housing shows the cracks circled in red in the pictures:




    These cracks are very old, I know the vehicle since 2011 and there were already. Do you see a risk if you do nothing to it or what should you do?

    if they have existed for 10 years, I would not worry at first.

    Hello Rolf,


    the fan housing is made of magnesium. Welding difficult, but not impossible. But welded areas are not as stable as before.

    Riss im Lüftergehäuse
    Hallo!
    Ich habe mein Lüftergehäuse (wo die Lima drin sitzt) zum Glasperlstrahlen und festgestellt das es an einem
    der vier Flügel einen Riss hat.
    Hat das schon mal jemand gehabt? Kann ich das schweissen lassen?

    Hello Rolf


    Typically, there are then also small fatigue cracks in the Lima support. Only visible after their disassembly. I have a crack on the outside of the ring. And now ? The new ring at mid-engine is cheap, considering the effort, and available. Who knows what the part will cost in the future or if MM no longer wants ? But where do you start ? > I go on. In the Wörschtcase the fan wheel crawls, you can already hear that. :) And then MM will hopefully still be able to deliver, 2035...


    also not "without" on the road...:

    Topic crack in the fan housing

    • Had I read through before, but a recommendation I could not read out there (welding, drilling or so let) and pinki) Pinki was last active in 2011! So no experience to expect.
    • I have now learned that the part is made of magnesium and thus the subject of welding is done for me (crack to, but loss of stability).
    • A new part to the special offer of 569€ or 660 at Porsche must not be without huge need
    • I will continue with the cracks and check regularly - based on photos.

    Hello Rolf,

    during my last engine overhaul I also discovered a crack in the housing. Since the crack was only visible from behind, I filled it with metal glue. For me, this was the most practical solution to extend the service life.
