The pushrod 4.0L OHV V6 (Cologne) is otherwise regarded as a durable 'tank,' but the cast heads are intolerant of overheating and are prone to cracking and gasket failure, typically appearing around 100k miles or after any single serious overheat event. The root cause is usually… Repairs typically run $1,000-$2,800. Severity: high.

The overdrive planetary is fragile (early units used a weaker pin… Repairs typically run $25-$3,500. Severity: high.
The 4.0L (both OHV and SOHC) drives the camshaft position sensor off a gear-driven 'synchronizer' assembly in place of a conventional distributor.
