for the Porsche 911

An external fluid leak may develop at the pressure switch; fluid will be evident in the trunk and the reservoir level will drop.

10 Reports

Engine Oil Leaks

for the Porsche 911

Over time, the engine can leak oil at various locations. Early-production vehicles require engine disassembly and modification to resolve leaks at the cylinder heads, oil return tubes, valve covers, timing cover, chain housings, case through bolts, and lines to/from the oil cooler.

10 Reports

Engine misfire or excess fuel consumption can damage catalytic converter

for the Porsche 911

If engine misfiring, rough running, or fuel consumption issues are not resolved quickly, the catalytic converter can overheat and fail.

10 Reports

Failed Hood and Deck Lid Supports

for the Porsche 911

The front hood and rear deck lid support struts may fail; replacement is required.

10 Reports

Brake hydraulic pump relay stays on

for the Porsche 911

The hydraulic pump relay can fail, causing the pump to run continuously, which leads to hydraulic pump failure due to overheating. Incorrect pressures will cause a low brake pedal or a high pedal effort with the possibility of other strange symptoms.

9 Reports

ABS light on due to moisture and corrosion

for the Porsche 911

The accumulation of moisture at major connectors and control units can cause various ABS/PDAS faults due to corrosion.

9 Reports

Inspect brakes regularly and investigate warning lights

for the Porsche 911

Pay close attention to warning lights and have the brakes inspected regularly—immediately address any brake problems. Hard driving habits will cause excessive brake pad and rotor wear. Aged brake fluid can cause numerous problems, including "waxy" buildup visible in the reservoir, so replace the brake fluid regularly. Special procedures are required to bleed/flush ABS pump.

9 Reports

Engine Valve Guide Wear

for the Porsche 911

Engine issues related to valve guide wear are common. Oil consumption, smoking at first startup, and valve train noise are all symptomatic of loose guides and worn valve stems. The valve train is complex and should be thoroughly inspected if a problem arises.

9 Reports

Distributor internal drive belt

for the Porsche 911

The ignition distributor's internal drive belt can fail and cause misfires and performance problems. After being updated, the distributor belt requires regular inspection.

9 Reports

Inspect secondary ignition system components

for the Porsche 911

Pay close attention to secondary ignition system components (distributor caps, rotors, cables, and connectors).

9 Reports

Early model belts and pulley

for the Porsche 911

In early models, the alternator/fan belts and bearing at the pulley must be correct. Updated parts are required for the alternator/fan pulley, as well as the belt tension monitor.

9 Reports

Engine won't turn over or cuts out

for the Porsche 911

If the engine won't turn over or cuts out at seemingly random times, it may be a failing relay for the DME system.

9 Reports

Failed cylinder head temperature sensor

for the Porsche 911

A failing cylinder head temperature sensor can cause erratic running or the engine to cut out entirely.

9 Reports

Creaking noise from the windshield and body/seal area

for the Porsche 911

Creaking noises while driving over bumps and when cornering may be difficult to diagnose, but are usually caused by the windshield at the body/seal area. The latest version seal and/or lubricant can solve the problem.

9 Reports

Targa top wind noise and water leaks

for the Porsche 911

Wind noise at the front of the car and water leaks at the vent wing are typical problems on Targa models.

9 Reports

ABS and related faults due to tire profile and wear

for the Porsche 911

In order to avoid ABS, Tiptronic, or intermediate differential faults/warning lights, correct tire profile and wear must be maintained.

9 Reports

Inspection of front control arm bushing and ball joints

for the Porsche 911

The front control arms should be regularly inspected for wear at the ball joints and bushings. Ball joint boot cracks/tears can lead to ball joint wear and failure.

9 Reports

Power steering pump leak from radial seal

for the Porsche 911

Fluid leaks at the right rear corner can often be traced to the radial seal at the power steering pump.

9 Reports

Rapid tire wear, especially rear tires

for the Porsche 911

Tire wear (especially in the rear tires) can be rapid and handling will suffer if the problem is not addressed.

9 Reports

Clutch release mechanism may fail

for the Porsche 911

The release mechanism for the (including the release arm bearings and shaft) can fail and cause stiff, binding, and possibly noisy pedal operation.

9 Reports

Clutch modification for early-production vehicles

for the Porsche 911

The release on early-production vehicles requires modification to make it compatible with newer repair parts.

9 Reports

Low, limp clutch pedal due to failed hydraulic components

for the Porsche 911

The hydraulic components for the clutch release mechanism at the clutch pedal can fail and cause a low, limp pedal feel.

9 Reports

Regular clutch fluid service

for the Porsche 911

The hydraulic fluid for the system may be overlooked; the fluid should be replaced regularly during brake fluid service.

9 Reports

Clutch issues due to contaminated clutch fluid

for the Porsche 911

If aging or contaminated is not replaced, there may be problems in the lines and actuating components, as well as clutch issues that are difficult to diagnose.

9 Reports

Transmission leak from spur gear drive

for the Porsche 911

The spur gear drive area is prone to leaks; the seals/gaskets can be replaced without removing the transmission.

9 Reports

Inspect CV Boots and Joints at Each Service

for the Porsche 911

The constant velocity (CV) boots and CV joints should be inspected at each service. Servicing the torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

9 Reports

Airbag light or dead battery due to normal operating clock

for the Porsche 911

A normal operating clock may cause the airbag warning lamp to illuminate or a chronic dead battery.

9 Reports

Dead battery due to faulty climate control module or incorrect battery

for the Porsche 911

Using the wrong battery or the failure of a climate control module may cause a chronic dead battery after the vehicle has not been used for a while.

9 Reports

Central warning system faults due to igntion faults or weak battery

for the Porsche 911

The vehicle central warning display can be sensitive to interference from vehicle ignition faults such as high voltage arcing anywhere in system. Battery capacity must be adequate to avoid electrical issues; also, the battery must be maintained and checked regularly.

9 Reports

Moisture within instruments due to small windshield leaks

for the Porsche 911

Moisture accumulation within instruments can be traced to small leaks at the windshield and can usually be resolved without removing the glass.
