Clean the back side of the crank vanes, if there is any coolant gunk or oil back there. With the CKS screws loose, rotate the crank to bring one of the three vanes into the CKS senors groove. Put the .030 feeler on top of the vane and with your thumb push the CKS down against the feeler. Tighten the screws and remove the feeler. Rotate to the next vane carefully, in case it's bent, and check to see if you can carefully insert the feeler. If you can't, remove the crank pulley and straighten or replace the crank trigger.
