Remember me. Thread Rating: 1 Vote s - 5 Average 1 2 3 4 5. Thread Modes. At first hello to all, I'm happy to be a member on STD. I'm Benjamin from Croatia, and I'm working about 3 years on my car.
I would like to introduce my project car that I have rebuild completely from ground off. To hold me short. Last year I completely rebuild the car from ground off.Mercedes W210 mTDI OM602 engine sound
Inside and outside. Inside it got a black leather 16V interior. And outside you can see. Now I working on a new engine.
I have buy a donor car with a 2. The engine is now fully rebuildet from ground off. I also modified the pump with 6mm elements from a OM pump. Her in Croatia it's difficult to get bigger elements. STD are not known here. So we modified the pump with help of Dieselmeken AB Thanks a lot on this place. The set up is following: -OM Turbo engine fully rebuilded -Pump modified with OM 6mm elements at 75ccm of fuel.
With the OEM turbo hp still the engine gona get a few kilometer worked. Open questions: -What turbo to use - target hp?

Garret turbos would be easier to get her in Croatia. T3 or T4 or something different? I have find out that the Holset hew would be a good choice is that true?
Learn More. I have a Hymer on a merc chassis, 2. The engine has been turbo intercooled, by JB intercoolers a few years ago, by another owner. Engine has done about k miles and is a good runner, starts first time, no smoke etc. My problem is lake of power. On a recent holiday to Italy, I had to drive it flat out all the time to keep up to 50 to 60mph, which rapidly dropped off to 25 to 40 on slight inclines.
I have tried all sorts, fuel filters, checked for blockages, been back to the turbo garage, who checked waste gate etc. It seems from what I gather on the net that this engine in NA form is 95bhp and obviously higher with the turbo.
But also on the web, it seems that the om in other variations ranges from to plus bhp tuned? My question is, is this normal speeds to be getting from this engine? If so, is there any way I can substantially improve this?
Tuning or complete engine swap for something else that will drop in without too much modification? I want to be able to cruise at 60 without being flat out all the time, and for it to maintain most of that speed on moderate motorway inclines. As its getting on a bit, nobody seems able to tell me. I get conflicting options from other owners, some say the 2.
Any help advice, much appreciated. Has the performance changed whilst you've had the camper? Is it worse than it used to be? What you want to push a big thing like a Hymer along is torque - lots and lots of torque.
Modern turbocharged diesels are brilliant for this but older ones less so.Portal Search Calendar Help. Hello There, Guest! Login Register. Login Username: Password: Lost Password? Remember me. Thread Rating: 0 Vote s - 0 Average 1 2 3 4 5. Thread Modes. OM Turbo has different Pistons, Head etc. Thanks a lot Max. This post was last modified:PM by Max. Exactly there's three version of 's 1.
Pistons, Con-rods, crankshaft, injection pump ALDA but the same head and third one is way much better Fortified piston, con-rod and bigger, improved water lines, oil lines 6mm IP, bigger pre-chamber Sorry for my bad english and hope this would help you. This post was last modified:PM by pmj Thanks a lot Max Hello from Finland.
My first here. That rod is the weak spot of that engine but changing to turbo rods and pistons it can take a lot of power. Of course, if you want to rev that sucker to rpm you have to put stronger valve springs etc. Those original turbo pistons are strong enough so you dont have to worrie about those. Just have to change turbo to holset hx40 or similar and check what happens to transmission That picture is from OM NA engine block with stock oil spray nozzles. OM engines are not direct injected.
OM are pre-chamber engines. And to barrote: OM crankshaft main bearing journal diameter standard size is 57,mm to 57,mm And OM main bearing journal diameter standard size is 57,mm to 57,mm I know that om crank is different than om 2.
The stroke is longer on OM engine. OM 2.Produced from to these lighter weight aluminum head engines replaced the venerable cast iron and engines of the 's and early 's.
Theses engines were more powerful and more fuel efficient. They did have a few teething problems but have proven to be very durable as long as they are treated and maintained properly. We can help you diagnose and repair common problems with these engines. They include the four cylinder engine that came in the D 2. If properly driven and maintained the engines actually require less ROUTINE maintenance than the older all cast iron and diesels.
Since they incorporate hydraulic lifters no routine valve adjustment is required. Air cleaners are mounted off the engine and thus don't suffer from vibration damage. Oil and fuel filter changes are easy. Motor mounts last longer. Belts last longer and don't require frequent adjustment, etc. I suspect for some that the prevention is just too much work. For others it may just be due to a lack of knowledge. Others may just be trying to spend some money. A number of these jobs can be quite expensive if you have a shop do it.
If you do it yourself you can save hundreds of dollars. That is where we can help. NOTE: If you have recently required one of these diesels or are considering purchasing one, here are my top SIX neglected maintenance items.
It requires removal of the intake manifold just to get to the glow plugs! Maybe that is why it is so often neglected. Glow plug hole reaming is a MUST on these engines. If you have no record of this being done recently get the reamer, do the job and replace the glow plugs.
Plan to ream the holes every 80, miles to extend glow plug life and improve smooth engine cold starts. A number of parts and kits and manuals are available for dealing with glow plugs. You should see some the the squirt no spray patterns I see on injectors removed from these engines.
Granted, the engine will run, but if you want to discover just how well it should run - install high performance Monark fuel injector nozzles. You won't believe the difference! Smoother running, more power, less smoke and leaps in fuel economy. These 60x engines are only as fuel efficient as the balance and spray patterns of your injectors. We have everything you will need to overhaul your fuel injectors in your own garage.
This is so common if your engine is not leaking now and the seals have not been replaced I guarantee it will be. Replace these o-rings before you have major leaks that can strand you on the road with some very expensive repair costs. Our kit will show you how to do this yourself! Kent will walk you through the steps to make the job doable for the average D. When they start to fail you can experience drastic power loss similar to a plugged fuel filter.
If this happens when you are away from home it can be very frustrating trying to find someone to repair it. The lift pumps are not expensive.
As a preventative measure to maintain peak engine performance I recommend the lift pump be replaced everymiles.Portal Search Calendar Help. Hello There, Guest!

Mercedes-Benz OM602 engine
First - a little bit of background I have a '93 W which started life as a E 2. I have installed an '87 OM turbo engine from an '87 D 2.
This turbo has the pressure actuated wastegate, as compared to the vacuum wastegate of later OM turbo engines. I have mated it to a 5-speed from an '85 D 2. I am also using a 3. The car drives well and has good power when the turbo "kicks in" at about rpm. This car has been my daily driver for several years now, with minimal problems. My larger goal is to add more power, probably in stages. First up would be to adjust the fueling of the pump and function of the ALDA.
My ultimate vision for this car would be to have a 20Valve OM Superturbo, perhaps mated to a 6-speed manual trans. It doesn't cost anything to dream. In the meantime, I'm trying to work out a logical flow of steps to perform so that when the time comes for a Dieselmeken pump, that most of the other obstacles have been removed. Right now, I'm thinking that stripping away all of the non-critical electronic and vacuum equipment is a good idea so that I can simplify the entire system.
I'd enjoy hearing about suggestions for step-by-step improvements, keeping in mind that I cannot afford to drop huge chunks of money at one time. Thanks, Steve. Now that would be a clean engine compartment. How are you currently running your tachometer? The tach is running off a basically stock electrical system. I swapped harnesses and the gauge cluster from the '87 D 2. Beyond the sensor that is triggered by the flywheel and the tach itself, I have not traced the wiring.
I assume there is some kind of signal "converter box" for the tach. I would keep the OEM engine driven vacuum pump for the power brakes, engine shutoff, and climate control functions.The successor of the OM engine family was the newly developed straight-5 diesel automobile engine OM from Mercedes-Benz used from s up to The Mercedes OM engine is a 5-cylinder diesel engine of 2.

It was available in either naturally aspirated or turbocharged variants with two valves per cylinder. The camshafts and injection pump are driven by duplex chain from the crankshaft. A separate single-row chain drives the oil pump. The camshaft operated the valves via hydraulic bucket tappets ; valve clearance adjustment is automatic. On many OM engines fuel injection is indirect. A Bosch PES in-line injection pump is used, with a mechanical governor and vacuum-operated stop control.
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. Some later versions of the 2.
