How does the intake plenum work on the OM642?
The intake plenum take the air from the filter and allow it to be sucked into the engine and mixed with fuel. The shape and rate of flow of the Plenum can make a large improvement to fuel engine efficiency on the OM642. Most headers are crying out for motorsport parts, although a few OEM provide fairly well optimized headers.
Do you need ECU mapping for Mercedes OM642?
ECU mapping will help unlock the full potential of all the mods you’ve done to your OM642. (In some cases, as the factory ECU is locked flashing is not an option, so an aftermarket ECU is the route to take, and many of these will outperform factory ECU’s but make sure it has knock protection and that you get it setup properly.)
Why does my Mercedes OM642 engine lag so much?
We’ve seen people spending a lot of money on turbo charger upgrades on the OM642 only to suffer the humiliation of seeing the engine block catastrophically fail soon after it’s completed. Big upgraded turbochargers will usually experience low end lag, and little turbochargers spool up more quickly but won’t have the peak rpm power band gains.
How much horsepower does a Mercedes OM642 have?
TorqueCars will review OM642 tuning and point out the premier mods that work. As fitted to the… Mercedes/Dodge Sprinter: 440 Nm (325 lbft). Mercedes/Dodge Sprinter: 140 kW (190 PS; 188 hp). Mercedes-Benz E350 CDI/Bluetec (2010–2016) Models 212.024

How does twin scroll turbo chargers work on Mercedes OM642?
Twin scroll turbo chargers divert the exhaust flow into 2 channels and push these at differently angled vanes in the turbo. They also increase the scavenging effect of the engine. It is common that there is a restriction in the air flow sensor AFM/MAP on the OM642 when considerably more air is being drawn into the engine.

Is the Mercedes OM603 a 3.0L diesel?
It’s kinda a shame Mercedes never made any bigger diesels than 3.0L except the problematic 3.5L ones. But I’m curious how the torque and horsepower and gas mileage (in similar-weight vehicle) compare, and whether anybody has ever put an OM603 into a W116. I had narrowed my MB search down to either an 86,87 300SDL or a 79/80 300SD.
Which is better the OM617 or the OM603?
think that speaks volumes… While the 603 is a much more civilized and powerful engine (148hp in the 300D Turbo and SDL) it does not come even close to the 617 as far as durability and reliability. The trap oxidizer is not the worst of its problems and because it is slightly more complex its operational costs are higher too.
How big is the Mercedes OM602 diesel engine?
The Mercedes OM602 engine is a 5-cylinder diesel engine of 2.5 or 2.9 L (2,497 or 2,874 cc). The 2.9 L (2,874 cc) was used in the 310D and 410D Mercedes-Benz T1 and the Phase 1 Mercedes-Benz Sprinter vans (where it was modified for direct injection), the Ssangyong Musso and Korando range and even in the 1996–1999 models of the E-class.
What kind of exhaust system does Mercedes OM642 have?
In addition, the engine has a cooled exhaust gas recirculation system (EGR/AGR) and uses a diesel particulate filter (DPF) to lower exhaust emissions even further. Some latest vehicles may have BlueTec AdBlue urea injection for NOx reduction.
Which is better the OM602 or the 300sdl?
Better handling…and almost as smooth a ride as the 300SDL but it is quieter and gets 8 mpg better than either the 300SD or the 300SDL. It has 210k miles and I have had no motor problems at all.
Where is the fuel lift pump located on a Mercedes OM602?
The pump is lubricated by a connection to the engine oil circulation and the fuel lift pump is mounted on the side of the injection pump.
Where do I find the piston specs on my car?
Micrometer, feeler gauge, a work bench, and the engine manufacturer’s service manual. The manual contains the piston specifications chart. The specs include clearances (maximum and minimum), piston diameter, and others. The idea is to ensure the measurements you get do not deviate from those in the manual.
Do you need standard or oversize pistons for your engine?
