- Thanks! Would it still normally smell like gas up front after a cold start though?
well anything is possible. gasoline fumes travel sometimes, but in the tC engine there is a VSV valve that sucks gas vapors from the tank to the intake manifold. That thing usually makes some rattle/clicking noises at idle when it's working correctly. But if there weren't enough vacuum (gas cap leak) could be the vacuum is out of control.
I'd expect anything odd to happen if the system isn't working correctly.. ok so you buy an $8 cap (again, I only have experience with the Stant brand) and the problem is still there, then you look at the vacuum lines around the VSV valve. That's the one with the green test cap by the air filter/intake air tube.
But for now I think you try a new cap, the toyota ones were always going bad every 2-3 years on me til I had enough and tried the Stant... not another problem.
