Thread: Cold Start

  1. #1

    Default Cold Start

    I have a 04 Trailblazer LS with a straight v6.
    For the past few days the temps outside have been below 20 Degree's When i start my truck cold i think im hearing a ticking sound. it only lasts a minute or 2, then goes away. never had this problem in warm weather. to me it sounds like a lifter knock, the ticking is in sync with the engine rpm's. I think its just thats there no oil at the top end of the engine during start up and that the cold is just slowing the oil down but a want another opinion.
    Is there anything else that could be causing this?
    What can i do to fix this?
    Do I even need to worry about it?
    Any feedback is appreciated.
    Thank You

    I don't know too much about that but I really think your right, oils cold and lifters are sticking until it's warm? maybe get an engine block heater and it will start easier?
