driving down the highway a few days ago i was hit with an "oil level low, stop engine safely" message. I added a quart of oil and the car seemed to begin running smoothly again. That was until yesterday. It began chugging violently at idle, and when i would give it gas, anything over 2100 RPM, there was a clicking noise comparable to when youre a little kid and you put a baseball card in your bike's tire's spoke. almost sounded like plastic on plastic. So needless to say, it's not moving until i get some input from you guys. One of my buddies who is really good with engines, albeit japanese engines, thinks that it's either a sticky valve or a bent valve because of the location and the sound that the engine is emmitting. Hopefully some of you guys have run into this before and have some good news.
