Some Smoke

Some Smoke
Hello.
I have a 1984 Delta 88 Royale Brougham with the 307 engine with 115,000kms on it
I am getting some smoke (smells like burnt oil) coming from the carburetor after driving and when the engine is hot.
That smell gets into the cabin when the vent is on.
I assume a gasket or pcv valve might be going but if anyone might have a better idea, please shout out!

You can test the PCV valve by removing the PCV valve from the valve cover with the hose still attached. Then you hold your thumb over the bottom of the PCV valve to hear it "click" closed. Sorry I wasn't thinking.
Does the car smoke on start up (worn valve guide seals) or smoke constantly while driving (worn rings or detuned carburetor)? A compression test is the best way to diagnose a worn engine.

Wow, thanks Olds64 for the fast reply!
No smoke on startup and no smoking while driving.
I took the air cleaner items off and noticed a small drip of gas. It almost looks as if the pipe was put on at an angle!

Be careful not to over tighten the valve cover gaskets. All you would accomplish is warping the valve covers.
The puddle of gas at the carb seems to be coming from the fuel inlet. That's a common failure point on Q-jet carburetors. It looks like your fuel inlet was installed crooked. Sometimes folks remove the brass filter from the fuel inlet, and fuse the inlet to the carb body with JB weld. Just make sure you run an in line fuel filter.
