check the compression, see how even they work out, then do a leak down test to see if the compression holds. I susspect worn, or broken rings

No way a valve cover leak will foul a plug. Do a leakdown test on ALL cylinders and see what your have. You prob. have worn rings.

oil fouled plugs is usualy a sign of worn valve guides or valve seals. broken or worn rings can do it but alot less common.
