Valve Spring Squareness

WARNING: This page is about a different car, the 2004 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

Measure the out-of-square on each valve spring.
- Turn the valve spring and observe the space between the top of the valve spring and the square. Install a new valve spring if out of square. Refer to ENGINE-2.0L ZETEC or ENGINE-3.0L (4V) for specifications and procedures .
