I have a 72 chevy and have checked the compression and check the pcv valve all good. But when I start my truck and get going i can see blue smoke coming out the back. The plugs look good. Is it the valve seels need to be replaced? Or should just have a valve job done on the heads. It does seam to use oil and I have stopped all of the oil leaking. Thanks for your help.
