Given that the pole of the polar coordinate system is at the origin of the rectangular coordinate system, and the polar axis coincides with the non-negative x-axis, the parametric equations of line l are: $$\begin{cases} \overset{x=1-t}{y=t}\end{cases}$$ (t is the parameter), and the polar equation of curve C is: ρ=4cosθ.
(I) Write the rectangular equation of curve C and the general equation of line l;
(II) Suppose line l intersects curve C at points P and Q. Find the value of |PQ|.
