"what are the most common problems with the 1979 Toyota Land Cruiser FJ43 engine?"

Question

Accepted Answer

Based on my research and knowledge of the Toyota 2F inline-six engine that powers the 1979 FJ43, here are the most common engine problems you should know about:

**Top 5 Common Engine Issues:**

1. **Carburetor Problems** - The 2F's carburetor is notorious for running lean, causing rough idling, stalling, and poor fuel economy. The carb often needs rebuilding or replacement, especially on vehicles that have been sitting.

2. **Valve Adjustment Issues** - The solid lifter design requires regular valve adjustments every 30,000 miles. When neglected, you'll hear loud ticking noises and experience performance loss. This is routine maintenance but critical.

3. **Oil Leaks** - Common leak points include the rear main seal, valve cover gasket, and timing chain cover. The 2F is known for weeping oil as it ages, but major leaks indicate seal replacement is needed.

4. **Overheating** - The cooling system can struggle, especially in hot climates. Common culprits include clogged radiators, faulty water pumps, and stuck thermostats. The FJ43's long wheelbase doesn't help with airflow.

5. **Low Oil Pressure** - Worn main bearings are common on high-mileage engines. You'll see the oil pressure gauge reading low, especially at idle. This often indicates an engine rebuild is in the future.

The good news? These engines are incredibly durable and parts are still available. Many owners consider these issues manageable given the 2F's legendary reliability when properly maintained.
