As the weather has gotten colder, my titans ticking seems to have gotten louder. Is this still just the injectors ticking away or could there be something more to it? I can hear it in the cabin(softly) when the A/C and radio are off. Only noticeable when idling or coasting in a parking lot etc.

One other symptom that I doubt is related, when i go to accelerate from a stop, right as the throttle hits load, there is a rattle(?) type sound just for a beif second as it starts to pull. Sounds like its coming from the bottom of the engine area.

Thanks for any suggestions guys. Happy New Year!

My money is on a failed timing chain guide. Your chain may now be rubbing on the inside cover near the water pump. It's fairly common on the vq's, I wouldn't be surprised if vk's do it too.
Sea foam will not fix a mechanical noise like that.

I can hear the normal vk 56 sounds underneath all that racket that I believe to be a loose chain.

If you have any mechanical ability you can do it yourself for next to nothing. I would not even consider replacing the chain unless it's damaged.
It's a time consuming job, but you should be able to replace just the guides.....While you're there maybe a water pump and tensioner too.
You tube is your friend.

My money is still on the chain guide.

Sea foam might help with sticky hydraulic lifters, but I doubt it'll help with solid cam followers.
