Long story short, my 2013 BRZ's engine had rod knock after 146k miles, so in the essence of time and money, I swapped in a used 2015 w/ 80k miles. It runs just fine but... it has what sounds like valve tick but I'm not quite sure.
At 0:05 is when the tick is real prominent, and 0:10 there's a pretty bizarre sound that comes out too that I have no idea what it could be.
Any thoughts?
Thanks in advance.
