Mercedes Engine Rebuilds
Our work
Providing professional and high quality Mercedes engine rebuild services including a 1 year warranty with every job. We are able to accommodate most modern Mercedes vehicles however we specialise in the OM651 & OM642 platforms. Completing repairs most commonly on the 2.1 & 3.0 diesel engines.
At Reconworks we hold stock for most Mercedes diesel engines so we are capable of providing an engine rebuild on these with great efficiency. However we are perfectly suited to provide a great reconditioning service on other platforms accordingly because of our great relationships with our quality parts suppliers.

Mercedes 1.8/2.1 Diesel OM651
Mercedes Engine Failures
Timing failure: A possibility with most engines the Mercedes 2.1 diesel engine is no exception. Most commonly we find that a timing failure is caused simply by ignoring the replacement schedule and so over time the chain breaks or stretches.
Fuel injector failure: We have taken in some 2.1 diesels which are knocking however these are not crankshaft failures. Fuel injectors are known to over fuel so they cause massive damage inside the cylinder. This is due to the injector spraying too much fuel inside the combustion chamber during its cycle before igniting it. The large amount of fuel creates a very high temperature environment subsequently melting and breaking up the pistons.
Turbocharger failure: Usually a secondary failure following a type of timing failure or poor maintenance. This could be a build up of particles or running the vehicle with low oil pressure after a failure. The disrupted oil pickup means the feed to the turbo is stopped and causes failure.
Crankshaft failure: Commonly caused by a lack of sufficient lubrication therefore often causing spun big end and main bearings.
Maintenance: Poor servicing is a major contributing factor leading to engine failure. If oil is not changed regularly a build up of particles and debris will build up inside the engine. So this and the change in oil viscosity commonly blocks oil galleries and the pickup therefore leading to failures. Because of this we are seeing the oil pumps failing in addition to turbochargers due to a blocked pickup.
Mercedes 3.0 Diesel OM642
Mercedes Engine Failures
Fuel injector failure: With some 3.0 CDI engine we have in fuel injectors are known to over fuel so they cause massive damage inside the cylinder. This is due to the injector spraying too much fuel inside the combustion chamber during its cycle before igniting it. The large amount of fuel creates a very high temperature environment subsequently melting and breaking up the pistons.
Timing failure: Only on the later 3.0 “blueefficiency” variants of the platform. In these later versions the double chain was replaced with a weaker single chain. We know this to stretch and snap causing engine failure.
Turbo failure: Much like the OM651 this is usually a secondary failure following a type of timing failure or poor maintenance. This could be a build up of particles or running the vehicle with low oil pressure after a failure. The disrupted oil feed to the turbo causes failure.
Crankshaft failure: A lack of lubrication in important contact points eventually leads to spun connecting rod bearings in addition to main bearings.
Lack Of Maintenance: Like with any engine, servicing is a major contributing factor to engine failure. This is because if the oil is not changed often a build up of particles and debris will compile inside the engine. Due to the change in oil viscosity this commonly blocks oil galleries and the pickup so therefore leads to failure. Oil pumps and turbochargers will usually fail in this instance.
