Most common problems:

Oil leaks

Older Porsche 911 engines, particularly the horizontally opposed 6-cylinder types, are known for developing oil leaks over time. These can occur at various points such as the valve covers, oil cooler, or crankcase seams.

Head studs breaking

The 1981 Porsche 911 engines are prone to head stud failures due to thermal expansion and contraction. This can lead to significant engine performance issues and costly repairs.

Timing chain tensioner failure

The mechanical timing chain tensioners in these engines can wear out or fail, leading to timing chain slack and potential engine damage if not addressed promptly.

Worn valve guides

Over time, the valve guides in the engine can wear out, leading to increased oil consumption and smoking from the exhaust.

Airbox explosions

The 1981 Porsche 911 engines, particularly those with CIS (Continuous Injection System), can suffer from airbox explosions due to backfires, which can damage the airbox and disrupt engine performance.

Overheating

Early air-cooled engines like the 1981 Porsche 911 can experience overheating issues, especially if the cooling system is not properly maintained. This can lead to engine damage if not addressed.

Fuel injection system problems

The CIS fuel injection system used in these engines can develop issues such as clogged injectors, faulty warm-up regulators, or other component failures that affect engine performance.

Worn piston rings

Over time, the piston rings can wear out, leading to compression loss, reduced engine performance, and increased oil consumption.
