OK, my 93 civic coupe has had its rpms running low enough wanting to stall. I checked for any vacume leaks and checked all the easy stuff. I realized that i should look at my plugs since i already know that Im burning oil (bad rings). Its been 4mths of on and off racing since i checked my plugs. I pulled out my spark plug Wire and oil was dripping from it and it was soaked. The same for 1-3 cylinders but not the 4th. Pulled out the plugs and they were covered in oil. Anyway what is the cause of this? Valve cover gasket? Its not leaking on outside though. Cam gear gasket? Where would this leak most likely come from. Should I be concerned about my engine blowing? Appreciate the help.
