To change the valve stem seals on a 1998 Toyota Corolla, start by removing the valve cover and timing belt or chain to access the cylinder head. Use a valve spring compressor to carefully remove the valve springs, then replace the old seals with new ones. Reassemble the components in reverse order, ensuring everything is torqued to the manufacturer's specifications. Finally, reattach the valve cover and timing components, and check for leaks before starting the engine.
To change the EGR valve on an '85 Toyota Tercel, first disconnect the negative battery terminal and remove any vacuum hoses or electrical connectors attached to the valve. Next, unbolt the EGR valve from the intake manifold using a wrench, and replace it with a new valve, ensuring a proper seal with a fresh gasket. Reconnect all hoses and connectors, and finally, reconnect the battery terminal. Start the engine to check for proper operation and ensure there are no leaks.

just bring the car to the trusted mechanic....
The PVC (positive crankcase ventilation) valve on a 1996 Toyota Tercel is located on the engine's valve cover. It is typically positioned near the rear of the engine and is connected to a rubber hose that routes to the intake manifold. To access it, you may need to remove any obstructing components, such as the air intake duct.
If it smokes on startup, it has worn valve seals. If it smokes while running, it has worn piston rings (and perhaps worn valve seals, too.)
