How do I check to see if my intake manifold has a vacuum leak inside and is sucking oil into cyclinders?

You might be able to take the carb or throtle body off so you can get a borascope down in there to check for oil. Also if its a single plane intake you might be able to look with just a small flashlight. A good sign is oil on the spark plugs. If thats so, it could also be you valve seals or piston rings, (they might not be gaped right). Check your plugs first. Remember no oil, no leak.

Thanks for reply, I can see by exhaust that I'm burning oil. It didn't smoke before I changed cams, so I'm thinking it's sucking oil into cyclinders thru bad intake manifold gasket. Thanks for help.
