• Q: How to Service and Repair Exhaust Valve and Intake Valves on 2003 Chrysler 300M?

  A: Before you service or repair the valve, take out the valve spring. Before you remove the valve, check the valve stem lock grooves for any burrs and remember which valves go where before you're done. After that, unscrew the valves from the cylinder head. Pour a bit of engine oil over the standard valve stems before placing them into the corresponding holes on the cylinder head. If the valve and seat have been reground, measure the height of the valve tip; if it is more than 43.65 mm (1.7185 in.) for the intake and 45.98 mm (1.8102 in.) for the exhaust, lower the height by grinding until it matches the specifications from the cylinder head to the tip of the valve stem. In the end, fit both the valve stem seals and valve springs into position.
