2000 Jeep Wrangler Owner Comments

problem #4

Feb 252013


  • 91,848 miles


The engine cylinder head was cracked between number three and four cylinders for a undetermined amount of time. Jeep would not confirm that a updated cylinder was made to fix the issue. I was told that Jeep had no records of cylinder heads cracking. A replacement head has been installed but the oil pressure is low due to the excessive bearing wear cause by coolant in the oil.

Wrangler 6-cyl

The engine has released more than one gallon of antifreeze into the oiling system in less than 500 miles. After removal of the valve cover, a fracture in the cooling system cylinder head water jacket has been found between cylinders 3 and 4 that permits coolant to enter into the oiling system. The dealership stated that the cylinder heads are known to crack without cause, can be replaced with a cylinder head that maybe prone to cracking again and in addition will require several more components to be replaced. The dealership offered no further information.
