The cost of replacing your valve guide seals will vary according to the make and model of your vehicle. The good news is the cost of the parts for valve guide seals is between $30 to $100 on average.

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 bad valve stem seals cause misfire?
faulty valve stem seals can lead to misfires, as they will allow oil to leak down the valves and leave carbon deposits that both restrict free movement of the valves and impede airflow around them. both conditions can result in misfires.
