Ok I did the whole tune up. Replace Distributor Cap, Rotor Button, Wires, Plugs. Now i have Smoke comming out of the Pcv valve(small filter) and misfiring from cylinders 1&3 at idle if i raise the rpm can't tell its misfiring. I was wondering could it be the Timing,or headgasket. If anyone knows what the problem is i would appreciate the help. I could use any information.
