• Q: How to Service and Repair Exhaust Valves and Intake Valves on 2002 Dodge Dakota?

  A: Before you can service or repair the valve, you must remove the cylinder head. Compress the valve springs with a Valve Spring Compressor Tool MD-998772A and adapter 6716A, then get rid of all the valve retaining locks, valve stem seals and spring retainers. Prior to removing them, clear off burrs in the valve stem lock grooves and make sure to know which valves they are for easy reassembly. Clean off all the valves and throw out those that appear burned, warped or cracked. Cover the deposits on the valve guides in your engine with a quality guide cleaner. Inspect the valve stems for damage; if they're worn more than 0.051 mm (0.002 inch), fit a new valve. Coat each valve stem with oil before putting them into the cylinder head. Should the valves or seats have been ground and the valve stem measures too high, the cylinder head should be replaced. Begin by installing new seals on all valve guides which you should prior to installing the valve springs and retainers. Use the Valve Spring Compressor Tool MD-998772A and adapter 6716A to compress the springs, insert the locks and release the handle at the end. When valves or seats are ground, you should measure from the bottom of the spring seat in the cylinder head to the bottom surface of the spring retainer (or from the top surface of the spacer if spacers are fitted). When the height is over 42.86 mm (1-11/16 inch), add a 1.587 mm (1/16 inch) spacer into the head's counterbore gap and that will lower the spring to the normal depth range of 41.27 to 42.86 mm (1-5/8 to 1-11/16 inch). To complete the job, attach the cylinder head again.
