Help! 98 502 efi loud clanking from engine
Fomula 353 w/stock 502. engine cut out in east harbor. Started back up and heard loud clanking from what seemed the top (end loud knocking). Shut it right down came in on starboard only. what should I look for when I pull the valve cover? anything problematic w/this engine (98 w/300hrs). Any help would be appriciated.

same thing
Good luck mine did same thing 95 502 490hrs pulled the motor for overhaul and it had a spun crank and the block is scrap so now will a new 540. Sure hope it is in your top end you can see with a compression check which cylinder s bad.
