I recently switched to stock 02 ls6 heads, the car ran fine for 2 weeks then took a shit. the car ticks really hard to, they said it could either be a bad ring or broken valve. the car has 43,xxx miles on it and the cams been in about 10,000 miles or so. why would my car all of the sudden get no compression in that cylinder? what would cause this :confused:.
