There is a chemical you add to the oil, idle the engine for a few minutes,
then change the oil and filtre. I used it to remove carbon build up on one
of the valves in my car. I measured the cylinder compression before and
after the chemical treatment and it evened out the compression on all 4
cylinders. I bought the chemical at Canadian Tire, a discount auto chain
store.

There is another chemical you add to the fuel but it had no effect on the
gummed valve on my car.

A good source of information on engine problems is the rec.autos.tech
newsgroup.
