My brother called me yesterday to ask for some help with his 1998 Jeep TJ. He was replacing the clutch, timing set and oil pan gasket. He had told me it had developed a noise in the engine a couple of days ago. When we dropped the oil pan I found the bottom of a piston.... :bawl: I am looking for anyone with a good used 2.5L or a 4.0L to replace the engine, or someone who knows a cheap mechine shop.
