The "Autozone" guys computer could not find a PCV valve part for this volvo..the advice ranged from bad rings to ignition cover seal. I did replace the oil cap and bought some oil additive to clean it up some...

My 1999 V70 w/ 198000 miles starting losing oil. Found a leak under my ignition coil cover and after removing cover found oil in each of my plugs. The car funs great with no codes. I suspect a head gasket but could it be something else? No evidence of coolant in the oil..yet.
