i just intalled a new crankshaft and meanwhile the motor hasnt been started for about 3-4 weeks, now that everything is back together when i start the car it idels fine, has good oil pressure, good fuel pressure but there is a loud clanking noise comming from the valvetrain what seems like the rockers but im not sure. the timing is right and the head is getting plenty of oil but i have no clue what a solution would be?????????
