SNC worth it to do loctite fix?
 

So I just picked up a 91 a few weeks ago and been doing a lot of research and I do have a wobble on my crank pulley, so my question is should I do the loctite fix or should I source a 1.8 from a yard ?? I do eventually plan on boosting it by the end of summer if funds are right but I don't want to boost it only for the crank pulley to fall off haha
