Recently had some issues with the Coil Pack misfiring on 2 and 4 and completly dead on 6. replaced Plugs ,Wires, and Coil Pack. That issue was resolved ok. Running on all Six again. However I did drive it this way for awhile. Needless to say had some gas run into the crankcase due to the misfiring and dead # 6. A mechanic told me I could pull the plug on the 6 injector without hurting anything. Which I did. Now I am blowing oil out the dipstick tube so bad a cop pulled me over today because of the smoke burning off the exhaust manifolds.
Now I'm not a complete idiot. I spent 15 years turning wrenches but most of my experiance went out the door when they replaced HEI systems. MY common sense is telling me I have some serious internal engine issues here. But I thought I might ask here to see if they is a new fangeled sensor or something I might be aware of due to my lack of knowledge of the newer cars and the way things are done nowadays. Oh yeah also..... PCV valve is sucking like crazy.

Sounds like blow-by to me. Check and make sure the PCV valve is not plugged. Otherwise, you may have serious engine problems.

Last time I saw that happening, it was on a destroyed but still running SBC in a boat. It amazes me that engine would even start and run. There were cracked ring lands and broken rings all over the place, and the blowby was so severe that smoke and oil was blowing out the breather cap. Check your PCV to make sure it's working right. If it is, you have major problems. I'd suspect broken rings or a hole in a piston.

Big bux repair.

This was happening on my old engine, you will have no compression as your rings are probably gone. All the pressure is forced passed the rings and looks for the easiest escape route, taking oil with it.

New engine time.
