  Q: How Are Exhaust Valves and Intake Valves Refaced Along with Their Seats on Dodge Stratus?

  A:

  The valves have a 44.5 to 45 degree face angle and the valve seats are set at a 45 to 45.5 degree angle. After refacing the valves, check the remaining space around them. While refacing valve seats, always match the size of the valve guide pilot to the reseating stones to get a smooth and perfect seat. Ensure that the runout of the valve seat when measured with a dial indicator does not go beyond 0.051 mm (0.002 inch) by the valve seat. Apply Prussian blue to the valve seat and if it ends up on the center of the valve face, you have enough contact. If the graze goes to the top edge, use a 15 degree stone to level the seat downward. If the graze is on the bottom, use a 65 degree stone to level the seat upward. As long as the angle and width of the seat are correct, worn or burned valve seats may be reworked; otherwise, a new cylinder head is needed. The intake seat should measure from 1.00 to 1.50 mm and the exhaust seat should be wider, between 1.25 and 1.75 mm. After finishing, examine the spring height mounted on the valve. After cleaning in engine oil, place the valve stems into place in the cylinder head. Should valves or seats have been refaced, ensure the look at the tip height of the valves, as the limit on intake valves is 47.59 mm (1.8737 inch) and 49.14 mm (1.9347 inch) for the exhaust valve; if high, grind the tip fittingly until it matches the numbers. Fit the valve seal/spring seat over the guide on each valve stem and make sure the garter spring is around the top of the seal. Place the valve springs and retainer on the spring seat, press the valve spring in place with a compression tool and close the locks and release tool. Where valves and seats have been refaced, determine the position of the springs from the top of the valve to the retainer at its bottom and use a 0.762 mm (0.030 inch) spacer in the head counterbore if the height is over 38.75 mm (1.5256 inch).

  Q: How to Service and Repair Exhaust Valve and Intake Valves on Dodge Stratus?

  A:

  With the cylinder head taken off, then use Special Tool C-3422-B and Adapter 6526 to compress the valve springs. After removing the valve retaining locks, valve spring retainers, Valve Stem Seals and the valve springs, you should push the rocker arms down manually. Be sure to clean away any burrs in the valve stem lock grooves before removing the valves, just to avoid damaging the valve guides and make sure each valve goes back where it came from. Put clean engine oil on the valve stems and then add them to the cutouts in the cylinder head. For each valve, replace the valve stem seals with a valve stem seal tool and press the seal squarely onto the guide where the stem enters. Because only a single oversize valve is provided, the same stem seal suits both types of valves. Place both valve springs and retainers, just enough to get lock pins through them without nicking the valve stems and while guaranteeing they are aligned correctly. Following the use of the valve spring compressor, make sure both of the locks are where they should be. After you reface the valve and seat, you should check the spring height and place a 0.762 mm (0.030 inch) spacer under the valve spring seat if installation height exceeds 40.18 mm (1.58 in / 3.7 inch). After installing the rocker arm shafts, drain the oil from the adjuster and move it to its collapsed position; measuring from this position, see that you have a dry lash of 1.17 mm (0.046 inch) for intake and 1.28 mm (0.050 inch) for exhaust. Once the last step for dry lash is done, add oil to the adjuster and set aside for 10 minutes to let the oil bleed down.
