Hey all, so I have a 2012 Scion tC that just got a transmission rebuild (second one because they bungled the first one) and exhaust repaired as the previous owner straight piped it. Anyways after getting both those done in the past week, I’m now hearing/feeling a knocking or rattle coming from the engine bay as I let out the clutch to accelerate. It comes and goes and I cant figure out what makes it happen. It’s not the same feeling as when you get the clutch out too quick/not enough gas. It happened once I think while in between gears but it happens maybe 25% of the time. I’ve already sunk wayyyy too much into this car, is there any chance it could be something simple? Loose bolt or mount? Any advice would be greatly appreciated!!
