As some of you may know, yesterday I attempted to install the CFM underdrive pulley. Well, it didn't end up that well as it seems that I lost timing (even when I followed instructions step by step) and the engine didn't want to start. After several trials and looking for the right timing the car finally started. I didn't hear any weird noises, no metal on metal, no nothing. I only left the car running for like 20-25 seconds and then turned it off. Now I'm finishing reasembling all the parts that I had to take of but I'm afraid of turning on the car again. So my question is, If I lost timing at first, does that mean that the pistons met the valves at some point? if the car started, does that mean that the engine is fine? Can it be ed up at higher revs? Should I start looking for new pistons and a new head?
