it is this easy however, you'll also have to disconnect the fuel line. Have confidence, and yank. My advice is watch the YouTube on how, so you don't snap it. WD40 helps.
As for the oil leak, mine does the same; although hadn't always. It started after high rpm, then a puff of white smoke. Still not certain what happened that day. And now, no matter what I try, I cannot get it to stop. If my oil level is the least bit high, it leaks. If I run high rpm for a time, it leaks. Searched everywhere, no one knows why or how to fix it. What's strange is it never did it for over 10,000 miles, and now always.
