I just bought my pickup. On start up my pickup exhaust puts out a lot of white smoke. I changed the PCV valves, spark plugs and air filter. I also noticed my oil was two quarts lows. My oil pressure is fine. I do not know what else could be the problem. I want to do what I can before I take it to a dealership. Thank you.

Take it to a garage and have it checked for a head gasket leak.
