1992 Isuzu 2.3l oil leak under intake manifold from drain tube

Would any one know what is causing the oil to “spit” out of an over flow tube that is located under the intake manifold. (I can not see clear under there) before I start pulling things of I would like to know what I am up against

Could you take a picture? I can’t recall engine oil having an overflow tube on any vehicle I’ve ever owned

If oil is spitting out there is either a great deal of blowby or lack of venting for the blowby. And the overflow tube is part of the venting system.
