Problems:

Oil leaks

Common in older BMW engines, often due to worn gaskets and seals.

Cooling system issues

Radiators, water pumps, and thermostats are known to fail, causing overheating.

Timing chain wear

Over time, the timing chain can stretch or the tensioner can fail, leading to poor engine performance.

Vanos problems

The variable valve timing system (VANOS) can suffer from oil leaks or mechanical failure, causing rough idling and reduced power.

Fuel injector issues

Clogged or failing fuel injectors can lead to poor fuel economy and misfires.

Mass air flow (maf) sensor failure

A faulty MAF sensor can cause poor engine performance and fuel efficiency.

Crankshaft position sensor failure

This sensor can fail, leading to starting issues and stalling.

Vacuum leaks

Cracked or damaged vacuum hoses can cause rough idling and poor acceleration.

Spark plug and ignition coil problems

Worn spark plugs or failing ignition coils can cause misfires and reduced engine performance.

BMW 735i 1988

The 1988 BMW 735i is a classic 7-Series sedan powered by a robust 3.4-liter, 6-cylinder engine producing 182 horsepower. Manufactured by BMW AG in Germany, this model offers a comfortable ride with four doors and an automatic transmission.

Problems:

Oil leaks

Older BMW engines, such as the one in the 1988 735i, are prone to oil leaks, particularly from the valve cover gasket and oil pan gasket.

Cooling system failures

The cooling system components, including the radiator, water pump, and thermostat, can fail and cause the engine to overheat.

Vacuum leaks

The intake manifold and various vacuum hoses can develop leaks, leading to poor engine performance and erratic idling.

Fuel injector issues

Fuel injectors can become clogged or fail over time, leading to reduced engine performance and fuel efficiency.

Timing chain wear

The timing chain and related components can wear out, causing noisy operation and potentially leading to engine timing issues.

Ignition system problems

Components like the spark plugs, ignition coils, and distributor can wear out or fail, causing misfires and rough running.

Head gasket failure

Overheating or prolonged engine stress can lead to head gasket failure, which can cause coolant leaks, oil contamination, and engine misfires.

Mass air flow (maf) sensor issues

The MAF sensor can become dirty or fail, leading to incorrect air-fuel mixture and poor engine performance.
