Hey dude, I've had this same problem and... well after blowing my engine and having it rebuilt... we found out that noise is from a thrown rod! I know its annoying and it sucks but the way Scion tC's are built the engine is upside down and if you go to a toyota dealership, just to have them look at it and to take the engine out it's $5000... I went to Thunderbolt in Houston Texas, to rebuild my motor cost me $2000 with a lifetime warranty! Good Luck!
@martinez2312 Ah sorry, nah. I am determined it could be rod knock although I have other issues at the moment. One of my cylinders has oil blowing back (piston seals are probably gone) I go through roughly half-a quart every full tank ~360mi but my MPG's are still 29-30 on HWY
@gtst23 Nope, some other guy has a similar video here on youtube and has a thread posted on ClubSciontC about it. Based on what I have gathered it could be adjustment is needed for the valves.
