My car was blowing blue smoke from the tailpipe,I put a new pcv valve on and it seemed to have fixed the problem for about a month.Then I noticed it started blowing blue smoke again. It is not continuous,it seems to blow smoke after the engine warms up. Got a solution? could the pcv valve be bad again? What powers the pcv valve? thanks.

Most likely the valve seals are worn allowing excessive oil to get to the cylinders or exhaust system
