Could it also be possible that it's coming through the gasket between the head and valve cover that circles the spark plug chambers?

I got oil in the #4 and oil is also seeping out through the valve cover onto the head from the back on the block too.

EDIT: or did I completely misread that and it's the combustion chamber?

I would suggest trying thicker oil like 20W50, it may solve the problem if the rings aren't too bad. If not, get ready to get butt raped by a mechanic.

That could be possible, but depends. Where exactly is the oil? The part where the coils sit? Or is the oil only on the side where the spark is?

Im assuming he's talking about the exterior area where the plugs go. If so, most likely the rings/gasket around the plug chamber is/are shot .

Yeah if it's on the outside where the plugs go then it would be those valve cover gaskets, if it's inside then it's probably rings

Mine was doing the same thing. Valve cover gasket was letting oil get onto the spark plug which in turn would make the spark plug wire boot pop up and then it would only be running on 3 cylinders. New valve cover gasket.

But that won't make smoke come out of your exhaust. That would be rings.

When you buy a valve cover gasket set the strip of 4 O-rings that go along the center of the valve cover come with it. If that is what is wrong you will probably need a valve cover too. You can tell buy seeing if the oil is around the crack where the valve cover meets up with the head inside the spark plug holes.
