My car engine just don't wanted to swing after no signs of any problems. Open car found oil on the two sparkplug chamber, bought a tappit cover gasket kit install itt and clean sparkplugs car still didnt swing, so i check for my cam valve timing shows out. Setup the cam valve timing eventually my car start and swing as long as i press the accelerator as soon as i lift my feet from accelerator the engine stall. So the car is not idling did anyone experience something like that and any advice are welcome to solve this. Now the other question how/why would my cam valve timing goes out it is on a chain
