I bought a 96 Corolla 1.8L for cheap and trying to fix this car. There is a loud ticking noise coming from the head on the left side. I put my ear on the oil cap and it sounds like it is right there. When I start the car, I have to keep my foot on the gas pedal to keep it running. My question to you corolla experts, is it worth it to try to fix it. I am not sure what is going on but it sounds the problem is in the head......Any suggestions?
