    I've heard of the ticking coming from the left fenderwell but not both. I'm a very new owner of a 2003 Zinc Yellow Mach1 so I'm not sure what the engine is supposed to sound like. It almost reminds me of my Dad's Duramax diesel :shrug: . Let me know what you think.

    I take it in and have it checked the ticking problem is a known problem on the 03's Mach/Cobra. With your BOD I would have thought you had the new head but you never know when the engine was built. I think they switched sometime in June.

    My BOD was 6/23 and runs strong with no ticking. SAE 280RWHP/306RWTQ

    the injectors make an audible ticking, especially at idle. I thought I had the tick on both heads till I realized this. From what Ive read I believe the tick from the heads can be heard at various RPM, nut just at idle.
