you should need one unless daryle made it his biaattthhh...So I was driving home last night getting on the freeway and I thought i'd give it some extra gas to make it fun. As soon as I do that I hear a loud bang and the engine just shuts off. Pull it over to the side of the freeway and wait a minute. Try to start it and engine won't turn over. Look into the engine bay and see a little bit of white smoke coming from behind the intake. I check and the pcv line coming from the upper into the lower intake popped off and sprayed some oil. Put it back in and still no luck. Had to have it towed home. Checked the oil from the dipstick and didn't see anything odd. Hopefully this weekend i'll have some time to pull the spark plugs and see if I can turn it over manually. Might need a new engine. I'm really hoping not but I'll find out soon. Wish me luck.
