    GOT A 2007 DTS WITH 71000 MILES ON IT, IT IS STARTING TO HAVE A RATTLING ALMOST KNOCK SOUND TO IT WHEN AT IDLE..NO POWER LOSS (oops sorry bout the caps) no noise when above idle ,engine is justplain noisy, had this same problem with my previous DTS, it sound like it needed oil, so i put another quart in it just to see, ran oober quiet there after. anyone ever find a dipstick (other than myself) to be wrong or had these problems before

    the previous DTS did not leak or burn oil at all, nor does this one,Attachment 114593

    getting low end vibration...alot of it is coming from wheel well area on left side of motor..to low for lifters I would say but I will pull up the blue prints, i know how to tear down heads on a standard V8...but theses seem to be a different animal.

    Might not be the problem at all but a cheap try and fix could be loud injectors, try a bottle of P/N 88861013 at you're Cadillac dealer. Put it in the gas tank at less then 1/4 tank fill it with 93 and go for a long hard drive, all the best.

    Hello BlueAngel#07,

    I apologize that you are experiencing a knocking and rattling sound at idle on your DTS. If you are interested in taking your vehicle to the dealership and would like my assistance in working with them, please send me a private message so I can discuss this issue with the dealership. I would need your name, contact info, VIN, mileage, and dealership you would like to work with. Thank you very much for taking the time to read my post and please keep us updated on the situation.
