Is the charging sytem giving you  12v minimum at the battery when revved. Many electronic ignitions do not function properly if they are not getting 12volts plus.

I can reccomend caswells sealant or tankcares products.

Have to admit ive never done that much damage to a lock washer at 60ftlb.

Lip raised. But how hard did you tighten it to cause that much damage? Try tightening it with a torque wrench.
