    I began noticing oil was burning some how, I was adding a quart every 2-3k miles. I try to change it anywhere between 5-6k miles. Now I have 174k and the valve cover gaskets appear to have leaked, allowing oil to flow right onto the spark plug wires. The car bucks upon heavy acceleration n now runs terrible. Its def burning oil bad cuz my exhaust is extremely hot and smokes as well as stinks, for the 1st time ever, i had that nasty rear bunper showing oil is clearing coming from the exhaust. i did maf sensor, Exhaust, and other misc electrical- check eng light issues around 70-75k miles. I bout it with 45k in 2006 so I'm thinking if I put money into it, it shoul b worth cuz I love the car. Also got in a bunch of accidents so the car is in awesome shape!.. Lol... Just wanted to ask if people had to dump thousands again and again- bcuz I can't see putting all my money into this car which was out of my league to begin with- but I paid it off! N don't ever want another car Payment. Can anyone please give me some advice.
