sitting at micky D's drivethrough...and truck says "clank" or "clunk" and dies....wont restart. It hasnt been doing anything weird, just out of the blue. Well this morning i talk to the garage and they think its a broken camshaft...but the peanut gallery swears its a broke timing chain. they want about 600$ to fix it i believe. This also includes repairing the speedo and a hole in the floor... It wants to crank...but it wont turn over... ideas?
