I'm having trouble with oil leaking from my oil cap were the pcv goes into and getting over all my plug wires ....Would it hurt anything if I just capped off the hole where the pcv goes ..thanks

You will need some sort of crankcase evacutation system. The PCV system keeps blowby from entering your engine oil and contaminating it and they system also keeps excess pressure from building in the crankcase which will ruin your rear main seal and possibly blow the dipstick tube out of the block. I would invest in a $2 PCV valve, $1 worth of new vacuum line, and a $5 breather. If that doesn't fix your problems you may check to see if the baffle fell of the valve cover.
