How do you replace valve stems and guides on a 1989 Jeep 4 Cylinder engine?
No, oil treatment will react in the same way as regular oil. Replace the valve seals.
yes heads need to be removed
it would be better to go ahead and replace it, but if you dont its ok.
Rubber valve stem seals are the parts used to keep tires from leaking around the valve stems. They provide a tight seal which also keeps them securely in place.
intake valves are the larger valves or if you count from from either end its number 2,3,6,&7 valve
If the valve stem seals are bad the intake valves will "suck" oil into the cylinders. One common indicator of worn valve stem seals is to take your foot off the accelerator for several seconds when going downhill, then watch for smoke when you step on the accelerator again. If you see a puff of BLUISH smoke, you probably have bad valve stem seals. The catalytic converter can become oil fouled so that would be another indicator that you might have valve stem seal problems.
valve stem seals
did you check the condition of the valve stem seals while you had the head off? bad valve stem seals will allow oil to leak into inlet manifold . the head needs to be off to change valve stem seals
Get a mechanic to do it. You obviously have no idea as to the complexity of the task. e.g valve stem seals, valve seats, warped head tolerances etc.

most auto parts stores sell a kit with everything you need for this task. Including instructions.
