I said alright then, got in my car, and drove home.

    Hi Swanka,

    Additional concerns? I still have the original concern. Nothing was accomplished other than wasting my time. I have not been able to hear the noise my engine makes on any other 3.6 except for the one the OP linked. I still do not believe the noise to be 'normal' and find it ironic how in both cases the service manager said "oh yea I hear that noise...doesn't sound right" but the tech automatically said "yea that's normal" without checking anything.

    I don't know which is worse. The fact that it ticks or the fact that it is considered normal for an engine to make such a noise in a Cadillac.

    I have an 08 3.6 DI and mine does not make any unusual noises except you can hear the injectors when the hood is open, but they are not very loud - just kind of a soft ticking..

    Re: 08 3.6 engine noise

    Just bought the 08 STS myself,.. and have the SAME TAPPING NOISE. It does not go away under any circumstances. I have read all forums, gathered info. from just about everywhere concerning these engines (3.6 V6 DI) and continue to get the same answers you do;..." these sounds are normal for this particular engine ." Injectors a/o fuel pump noise. Seems as though with all the complaints about these engines, GM should,.. by now, have some factory fix, or retro solution, or something. After all, these are CADILLACS,.. not lawn mowers ! PLEASE, if anybody out there has found a true remedy, PLEASE POST.

    Via mechanics stethescope or the old hose trick, it ought to be possible to narrow down the source of this noise.

    Good luck!

    Hello oldcaddybuyer,

    I apologize for your dealership visit. I do understand how that can be frustrating, especially when the manager states that the noise does not sound right. Have you thought about taking your vehicle to another local Cadillac dealership to have another opinion?

    Sincerely,
