engine on 1993 Mitsubishi Diamante

Good morning...I have had a couple of issues with the car like a strong smell coming from my muffler along with with smoke...the engine light came on a couple times along with it not wantingto start when warm)changed the pcv valve noticing the hose from the engine to the air filter(mass air flow and such) contained a huge amount of oil.//(blowby)..what can be some other causes than a bad pcv valve.???..i was told intake/valve cover gaskets by one and crank pressure something by another...please advise....The car has 208.000 miles on it but the engine has about 100.000....SHARYN

Need to check the compression and then check for a defective head gasket, just to get a sense of what kind of shape your engine is in as of now. Does your engine need to have either oil or coolant added between oil changes?
