Is It Expensive To Replace Piston Rings?

How do I know if I have bad valve seals and piston rings?

It simple to test.

If you accelerate and blue smoke continues until RPM is high all the time these are rings.

If you see smoke just few seconds after acceleration these are valve seals.

The more idling time the more blue cloud with acceleration also indicates the valve seals are bad..

Can you replace piston rings without removing engine?

Yes it will. Really bad rings will instantly show low compression. Then pour a few tablespoons of oil down the spark plug hole and the compression will get better.

How long should Pistons last?

Most will last 60,000 miles with no problem, but consult your handbook because some cars differ.
