89 B2 diesel build thread

hell yeah. looks like a great time.


you may be overfueling a cylinder....usually raw diesel smell and prodigious smoke though. seems a head gasket would be obviously causing other issues. timing is critical and elevation as well.

regardless.....under load they simply make allot of heat. even the tdi.

i run heavy in my lightest configuration for 150 hp at 6000 plus pounds.

weigh it in trail configuration.

this is why i suggested to gut the core and maximize radiator capacity.

i only have issues towing unless over 5k feet. it runs warmer over 6k ft. its the main reason i want an inline pump....easy to adjust compared to the rotary.

Yeah, I’ve been playing with timing. I think between that and being at high elevation didn’t help. I put it back to where it was when I got it. Because it wasn’t overheating then, and that was at the same time I did the gears, and lockers. And moving back made it smoke a blue smoke more, mileage actually went down. Yesterday I advanced it more than I had it before to see what it’s like. People say if you advance them to much they won’t start easy. Well hot or cold no problems starting. I’m shopping for a radiator right now. I’ll pretty much do as you suggested, building my own core support will make it easier to put in an inter cooler. Idk I’m gonna gather parts for a TDI. But the only way to get more power out of this OM617 is to do a turbo and have the injection pump upgraded. About 3k, I’m just not sure if I want to take that kinda of chance on this 40 year old engine….. but funds are pretty tight right now, so we’ll see. I’m done for this year for big trips. Next year we are planning on a couple trips. Big one being a trip to the rubicon, idk we’ll see what happens. Idk getting the coolant system under control will help a lot. I’m going to be playing with front coils, I really like the early bronco ones I currently have but they are sagging, and wont stop. It’s definitely a lot more stable, it won’t unload so bad now. I’ve even wondered what coil overs would be like. Idk I can buy a lot of coils haha

maybe a chinesium gt30 and repop your injectors. definitely going to get rich at 9k elevation. though one of those ebay turbo units could definitely do damage it it grenades.

Doomsday diesel did a pretty good test, he recommends a HE221 he says it’s the best size turbo, he says the gt30 is to big. Idk him and and other outfit sells the he221 it’s like $700 bucks with his oil regular kit. Others back him with what he has dyno tested. It’s just decent money. Nothing can be done other than to rebuild the injectors, no one makes anything becides stock nozzles, the injectors were supposed to be rebuilt, I found the receipt in the glove box anyways, and they definitely been messed with. It’s why I haven’t done anything with them. But that leaves me to the injection pump, which everyone claims put out all the fuel they can stock. Some people claim you can take off the rack stop and gain some fuel at the higher end… I don’t know if I like the idea of removing the fuel rack stop. Haha I clamp the waste gate line off and I can hit 15 psi on a hard pull. And this thing doesn’t smoke at all… after adjusting my timing again all the blue smoke is gone and it’s definitely running better. Idk I’ll just keep my eyes open for used parts, they do come about every now and then. I should go talk to the local injection pump shop, maybe they can just order the parts to put bigger plungers in it and that would save me some money since I wouldn’t have to pay shipping. And being there’s nothing wrong with my current injection pump and I have a spare haha

Haven’t been on in a while. It getting onto winter. I swapped the front coils to brand new wild horse 3.5 lift progressive coils. I got it together enough to go in a toy drive run. I’m going to an inside coil bump stop. I modified my stock coil buckets. Then I ordered a bigger radiator. Build a core support right now. It’s 26 by 19 and a true cross flow. If it overheats I’m done with the diesel…. Lol

I’m also hauling it to sand hallow end of February for united by bronco. Should be fun! Pretty excited. Never done anything like it before. Probably be the only b2 there.

Mercedes builders and others alike are keen on the HE221. BenzForce has a catalog dedicated to parts for this great little turbo

not a fan of progressive coils unless you can adjust for sag easily....





hell of an expensive picture of fords.... mine would be the fat kid ford nobody likes if it was there.....
