I am ready to transplant a 1984 2.2 engine into an 87 190E and am looking for input as to the issues I am facing. What help in advance can you offer regarding hookup of vacuum in order to get things working, ignition, IP ect.? I am new to the Mercedes forum and have looked at some of the posts, all helpful but not exactly specific to initial startup requirements. I plan on a simple push button glow sys. unless otherwise persuaded. Thanks

do you have only the engine from the 84 or the entire car to swap from?

Swapping the ignition housing covers vacuum shutoff, and the glow harness can connect to existing connectors in the fusebox easily, some splicing involved.

See here

My buddy pulled the engine out of his car and included most all the dsl spc. eng. related wires. I do not have the car, scrapped.

Very interested in following your swap. I've thought about the same but haven't run across any threads where it was completed. I've read everything's a direct bolt in and if so a hillbilly glow plug and shut down can be easily rigged up. Good luck!

Why not just buy a used 190D? You won't have to re-invent the wheel and won't end up with an altered vehicle.

The radiator from the gas car will not work on the diesel motor ,everything is opposite positoned.A radiator for the diesel 2.2 can be found out of a 2.5 car I know for sure , not for sure but maybe even a 300sdl radiator will work.If you havent done the frt or rear main seal it sure would be a good time before install.This old 2.2 engines are notorious leakers at these points.All 3 Ive owned in the past including the current one was and is a puddeler.You can get use to a spot or 2 but when it whizzes oil is another thing all together.

I have done this conversion. The gas radiator works just fine. You need to find the right hose. Gates-22436

Thanks Guys for the input, I'll keep moving forward. Other thoughts welcome.

I am in the midst of this conversion. I'd rank it low on the complexity list. Glow relay, shutoff, engine mounts, front section of the exhaust, different hoses....thats about it. I'll take some pics of my progress. I hope to have it on the road before the end of July. Gasser is already pulled out, I am prepping the diesel powerplant setup/trans to put back in, and I am re-doing the driveline on the car (flex discs, carrier/bearing) Radiator works just fine from the gasser.

Hey great to hear I'll have extra help on this. I am somewhat perplexed by all the vacuum sys. can someone explain the basics of it to me? How does the IP shutoff work and what other vac. functions will I need to make sure they are working inorder to get this car running and driveable? Hope to start putting eng. in this week. Thanks

The diesel engine has a vacuum pump. The brake booster, shutoff valve, and climate control operate off of it. For the shutoff, a line goes from the vacuum supply to a valve on the side of the ignition switch housing, which opens the vacuum supply to the second line back to the shutoff valve on the injection pump when the key is off.

Am I corrrect in thinking my 190e car (gas) does not have the correct vac. contr. ingnition switch to control my IP shut off? What is the best option if this is the situation, what do I do? Thanks

The simplest and most straightforward way is to go manual for both glow and shutoff. I used a Ford starter solenoid for glow plugs and for shutoff hooked up to a vacuum solenoid to a switch on the dash, but a better solution is to use a switchover valve.

No the gas car will not have the valve on the ignition. If you cannot find one from a 190d then your best bet would be a switchover valve that electrically controls the vacuum.
