0331 Cylinder Head Question

[Jim Cissell]

I'm new to this forum, but very interested in the 4.0L engine.

I have a 2000 Wrangler, with a bit over 100K miles on it. The build date on the vehicle was Oct'99.

I know there isn't a definitive answer to this, but are more of these early production heads actually fine, and don't crack, or is there a good chance it will, and it's just a matter of time?

I take extremely good care of my Jeep (and this engine!) but also realize the crack prone issue isn't necessarily related to maintenance.

Thanks for your insignt...

Jim
