Umm symptoms, ha, when you are driving down the road, get on teh gas, and the chains jump a couple teeth on the cams, and your car is running horrible. Or after you "fixed it the first time" , you go outside to start the car, and it just cranks forever, never turns over.
I had the usual start-up clack, and i seemed to also have some lifter knock as well. I guees the tensioners finally gave way, and needed overhaul.
