VALVE SPRINGS, RETAINERS AND SEALS | REPLACEMENT
(Refer to illustrations 17.9, 17.15, 17.17)
NOTE: Broken valve springs and defective valve stem seals can be replaced without removing the cylinder heads. Two special tools and a compressed air source are normally required to perform this operation, so read through this section carefully and rent or buy the tools before beginning the job.
If compressed air isn't available, a length of nylon rope can be used to keep the valves from falling into the cylinder during this procedure.
- Refer to Section 4 and remove the valve cover from the cylinder head. If you're working on a V6 engine and all of the valve stem seals are being replaced, remove both valve covers (see Chapter 2, Part C).
- Remove the spark plug from the cylinder which has the defective component. If all of the valve stem seals are being replaced, all of the spark plugs should be removed.
- Turn the crankshaft until the piston in the affected cylinder is at top dead center on the compression stroke (refer to Section 3 for instructions). If you're replacing all of the valve stem seals, begin with cylinder number one and work on the valves for one cylinder at a time.
Move from cylinder-to-cylinder following the firing order sequence (see this Chapter's Specifications).
- Thread an adapter into the spark plug hole and connect an air hose form a compressed air source to it. Most auto parts stores can supply the air hose adapter. Note: Many cylinder compression gauges utilize a screw-in fitting that may work with your air hose quick-disconnect fitting.
- Remove the rocker arm (see Section 10) for the valve with the defective part. If all of the valve stem seals are being replaced, all of the rocker arms should be removed.
- Apply compressed air to the cylinder. Warning: The piston may be forced down by compressed air, causing the crankshaft to turn suddenly.
If the wrench used when positioning the number one piston at TDC is still attached to the bolt in the crankshaft nose, it could cause damage or injury when the crankshaft moves.
- The valves should be held in place by the air pressure. If the valve faces or seats are in poor condition, leaks may prevent air pressure from retaining the valves - refer to the alternative procedure below.
THROTTLE PRESSURE CABLE OR ROD | ADJUSTMENT
(Refer to illustration 4.3)
- The throttle pressure cable (four-cylinder models) or rod (V6 models) controls a valve in the transaxle which governs shift quality and speed. If shifting is harsh or erratic, the throttle pressure cable or rod should be adjusted.
- The adjustment must be made with the engine at normal operating temperature.
- Loosen the cable mounting bracket lock screw and position the bracket so the alignment tabs are in contact with the transaxle casting (see illustration). Tighten the lock screw to the torque listed in this Chapter's Specifications.
- Release the cross-lock on the cable assembly by pulling up on it. To ensure proper adjustment, the cable must be free to slide all the way toward the engine, against the stop, after the cross-lock is released.
- Move the transaxle throttle control lever clockwise as far as possible (against the internal stop) and press the cross-lock down into the locked position.
- Check the cable action. Move the transaxle throttle cable all the way forward, release it slowly and make sure it returns completely.
- Loosen the adjustment swivel lock screw and make sure the swivel slides freely along the flat end of the throttle rod. If it doesn't, disassemble the linkage and clean or repair it as necessary.
- Move the transaxle throttle lever toward the engine, hold it firmly against its stop, and tighten the locks crew to the torque listed in this chapter's Specifications.
- It's a good idea to lubricate the linkage at this point (see Chapter 1).
