oil in spark plug holes?
Oil is leaking into the no. 1 spark plug hole and has started into the other two. Was checking the car over and found that the spark plug holes were half full of engine oil. All the valve cover bolts were tight, and as far as I know, the valve cover has never been removed. I was told to change the pcv valvue. Is there anything else i need to do? and is this a commom problem in cars? what do you think would be a reasonable price to pay to fix this?
