From everything you’ve described thus far, the only thing left to do is to pull the rocker on that number 4 intake and make sure the pushrod looks OK. The fact oil is coming through the pushrod to the rocker arm tells me the pushrod is seated In the lifter. If the pushrod is OK that lifter and camshaft are done. Because that cam lobe is sawed off The engine is now full of metal and all of the bearings are full of it too. By the time you spend the money to fix all these problems you still have an engine of unknown quality and a flat tappet cam. You can go through all the hoops for the repair and still face the same issue of wiping out another camshaft. In this situation I advise a customer to buy a warranteed $2000 GM brand new roller cam 350, spend the additional $500 in parts to convert as necessary and be done with it.
