Re: Bizarre engine defect!

The casting date is definitely J181. I thought that GM and most other manufacturers did not use the letter "I" in their castings because it would be confused with the number "1". So if you take "I" out of the alphabet then the following is the result A=Jan, B=Feb, C=March, D=April, E=May, F=June, G=July, H=August, J=September, K=October, L=November and M=December
