Well i got bored today so i started to put on my new radiator hoses, and i decided to investigate the problem of why my wastegate didnt seem to be actuating. When i removed the actuator arm from the little thing that connects to the flapper i found that the flapper is sticking somehow. I cant even really explain the situation but you have to like jiggle it while trying to open it. sometimes it opens and sometimes it doesnt. What are my options to fix this? is it possible to replace just the flapper and the arm that controls it or do i have to get a whole new hot side of the turbo?
