    Good Afternoon.  We just found the engine 3 charge air pulsation damper failed.  Anyone happen to have a spare or know where one can be found.

    Chuck,

    In what way did it fail, and what were the symptoms of failure?  We don’t have anything for you (we have 34SG’s anyway).

    I’ll be happy to share photos if someone can tell me how to get the Insert Photo button to work.  But basically the charge air pulsation damper cracked and came apart.  Reason unknown at this time.  On hind sight we believe the symptom of the failure occured when we noticed a thick snot like substance on the back flush filters – the pulsation damper failure caused a large amount of fine grey metal particles to enter the oil – the Wartsila technician believes the particles made their way past the piston rings when the air was injested into the cylinder.

    We perform monthly oil test.  The particle count went up (like a poorly gathered sample) but came down on subsequent samples.  We found the failed pulsation damper by accident while opening the engine to determine where the metal particles were coming from.  Fortunately, so far we haven’t found any sign the metal made it past the filters.

    Update.  The pulsation damper mount closest to the charge air cooler unscrewed.  The fasteners are in good shape so it does not appear that the bolts broke.  Once the mount came loose the pulsation damper beat itself up even causing the pipe to shatter and fail.  We have broken pieces all up and down the charge air receiver.
