Given that the pole of the polar coordinate system is at the origin of the Cartesian coordinate system, and the polar axis coincides with the non-negative half of the x-axis, the parametric equation of line $l$ is: $$\begin{cases} x=-1+ \frac { \sqrt {3}}{2}t \\ y= \frac {1}{2}t \end{cases}$$ (where $t$ is the parameter), and the polar equation of curve $C$ is: $\rho=4\cos\theta$.  
(1) Write the Cartesian coordinate equation of curve $C$ and the standard equation of line $l$;  
(2) Suppose line $l$ intersects curve $C$ at points $P$ and $Q$, find the value of $|PQ|$.
