People have told me that you hear a clicking noise and i started to hear it in my engine, so this is why i asked. Do I go to the mechanic shop and ask them to run a compression test or something? Have anyone done this? How much does it usually cost to see if you do have a bent valve? And how much does it usually cost to replace and fix a bent valve? Thanks guys.
you'll also get misfire codes in the cylinder where the bent valve is (cel)
it may not be visible and may only be a pending code, which only toyota diagnostics can register. which means it could be that your getting a minute amount of missfire but your ecu doesn't 100% think its misfire yet, and will pop a pending code, then the next time that same event is triggerd it displayes the cell.
