so i was just wondering because my valve cover started leaking 3 weeks ago and i been driving it in town not trying to push it because it only seem to leak when i go on the highway but anyways i was going to fix it this weekend and now i noticed that 1st gear skips to 3rd gear.. its automatic by the way so my question is did i mess something up
or is just the oily spark plugs because the spark plugs were oily ? i just need to know because i only have cash to fix my valve cover right now im not sure what else it could be? help please
