Hello all. I just bought my srt6 (60,000 miles) a couple months ago. so i did a little maintenance work on it last weekend; changed the oil/filter, air filters, and cabin air filter. all went well but now when i start the engine, i can hear a sloshing sound and it sounds as if it's coming from the filter boxes. it only lasts for about a minute and then goes away and only happens on the first start when the engine is cold. any ideas of what may be going on?

 

The only thing different between a cold and hot start is the aux air pump runs for 30-45 seconds on a cold start.
But this is usually just a high pitched whine, as that motor turns about a gazillion RPM.

 

A gazillion is a ginormous number!
