Hello everyone, I am trying to diagnose this new sound I've been hearing on my 06 V8 4runner. I recently changed out the timing belts/water pump with all OEM parts and recently started hearing a strange almost vacuum sound upon start of the vehicle. As per the video posted, the sound is audible at the 10-second mark and after everything after seems ok. Can't say there are any other engine-related issues I may have. Please let me know what you experts think!!
