Problems:
Oil leaks
The 1991 Porsche 944, like many older vehicles, can develop oil leaks from various locations such as the oil pan gasket, valve cover gasket, or camshaft seals.
Timing belt failure
The 944's engine uses a timing belt, which can wear out or break if not replaced at recommended intervals, leading to severe engine damage.
Cooling system issues
Over time, the cooling system components like the radiator, water pump, and hoses can fail, causing overheating and potential engine damage.
Vacuum leaks
The rubber vacuum hoses can become brittle and crack, leading to vacuum leaks that can cause rough idling or poor engine performance.
Fuel injector problems
Fuel injectors can become clogged or fail, leading to poor fuel delivery, misfires, and reduced engine performance.
Head gasket failure
The head gasket can fail, leading to coolant mixing with engine oil or causing compression loss, which can result in overheating and engine damage.
Worn engine mounts
Engine mounts can deteriorate over time, leading to increased engine vibrations and noise.
Mass air flow (maf) sensor issues
A faulty MAF sensor can cause incorrect air-fuel mixture readings, leading to poor engine performance and reduced fuel efficiency.
Ignition system problems
Components such as spark plugs, ignition wires, and distributor caps can wear out, leading to misfires and starting issues.
