2000 Cherokee Sport 4.0
My Jeep was mfg. in 10/09 I am hoping it does'nt have that dreaded bad head. How can I tell? Fortunately, so far ( 112,000 mi.) no problem.

Don't worry about it...just drive and enjoy. Not all of them go bad and, when one does, it's not a crisis. Check your oil often (every day is not a bad plan on a ten year old truck) and take action when/if you find evidence of water.

X2, it's not as common as everyone will make you think and when it does fail, it's not catastrophic as long as you catch it fairly soon. Water in the oil (not the white stuff on the bottom of the oil cap) will make the oil look like a milkshake and will destroy the bearings if not repaired so just keep an eye on it. You do check your oil every time you fill your gas tank don't you?

As far as not being a common problem, I don't necessarily agree with this. Every Jeep owner I know that has a 4.0 2000-2001 (all w/0331 head) has had a cracked cylinder head. When I first called to buy a new head, the supplier was out of stock due to the demand. Go figure....
