Been reading up on th infamous "0331" Cylinder Head and it's habit of cracking between cylinder 3 & 4. I read a poll on how many have cracked on this forum alone and it was somewhere less than 50 instances. This brought me to think about how many weren't defective (I have a 01 TJ that still running this casting). Long story; short........ I found this primo "0331" casting in a "Pick-n-pull yard for $28 that aside from a little clean-up would perfect for installing on my Renix. Think I'm crazy?.... as my '89 XJ has never been touched and I think it's due for some valve work.
If you would please post if you have a known "0331" with some mileage on it sans cracking......include the production year and mileage in your response. I want to see your success story!
