Pierre down here in Florida got a car running of my uncle's. It is a 1969 220D which had been sitting in a garage since 1981!! He lubed the rings and cylinders for days and got it to turn over by hand and eventually got it running. Sure, he had to do some stuff to the fuel system but that is still pretty amazing.

I'm thinking a little B20 in the summertime might get some of the gum out. (If not cost a few filters.)

Well I took it into the shop to hopefully have the ip set, and it turns out the IP I pulled is bad, as well as the injectors. He quoted close to 3k for repairs....to much for me...but that was for a brand new ip and injectors. If I had the money, I would put it out. He says to just look for a good used engine with 150k/160k on the od. In a few days I will put the original ip back on and the original injectors to see if I can get the original unclogged or if it has also been ruined....if thats the case I suppose I will look around for a new engine...seems the cheapest way out.

Re/re an IP sounds scary, and it's a big job, but it's completely do-able with the knowledge you can tap on here.

You can rebuild the injectors yourself or (my advice) buy a new set of nozzles from Phil and take them to a Bosch shop for installation and setup.

I was thinking about getting a used ip, but my problem is how do I know its actually good?

I have the original one from the car here, but I have no idea if its good or not. I've been browsing the net for someone local that could test and clean it but I've had no luck.

The injectors are the easy part, as you say I can rebuild them. I'm also curious about how good the bosch remans are? I know monarch nozzles are the recommended ones, seeing that bosch has went way under. Still curiosity you now

Hey, nice Dodge Dart in the background

Wow if the lift pump, pump and injectors were that bad from the WVO, to mention nothing of the tank, then it's time for a used motor.

You could do worse than put out a feeler in the "Used Mercedes Parts for Sale and Wanted" subforum on this board (make sure to indicate how far you're willing to travel, if at all, for what you want).

Sorry, my bad.

I was rushing when I wrote my first reply (I since deleted it) and had not read all your posts.

See my revised reply. My call would be that if WVO mix made such a mess of everything else, the motor itself probably isn't worth dealing with.

If you can put your hands on a diesel compression tester, that will give you a real indication of what you've got. But my bet would be on the news not being great.

No problem.

I will go get a cheap compression checker and see the results. I am just hesitant to replace the motor. I have taken it on the freeway a few times already. It seems to run better then my other mercedes. Its smooth and I've gotten it up to 95mph with out a problem. Then once its warm, it runs with out any smoke or roughness. Its slow to take off and the first start-up it idles rough and white smoke...I figured this out to be the injectors...maybe I should just face the music and replace..

If u got it up to 95 mph, the IP must be working ok to deliver the fuel to go that fast. Just drive it with lot's of Italian tune ups, run synthethic oil for its cleaning ability, adjust the valves again. Don't waste ur time putting the IP that sat with wvo back in. It will need total diassembly and cleaned of the wvo gunk. If the wvo did not have any water, the IP may still be serviceable if it was full with wvo and no air, otherwise it may have internal rust and good for a paper weight only.

I think you are right.

What I am going to do is, disassemble and clean the injectors that were originally in the car...they were put in less then 20k ago. And put those in the car. As the ones that are in it now I know aren't good nor matched.

I also think you are right on the original ip. The spin on filter was still on the car when I got it. It was gunked but the filter was full of clean fuel. If it was bio or diesel I don't know. The papers I got said it was used with both wvo and bio.

After I change the injectors, I will start the Italian tune up for awhile and see how it acts. The car pops right off but does stutter while warming up. But there is no cranking for 5mins or longer till it catches. I will also set the timing of the ip with the drip method.

I also found these guys, not sure if anyone has used them. But it says they will test and inspect the ip for 60$. I emailed and asked for a quote, still waiting for a response.

Ok perhaps I was confused by the chain of posts. If it idles evenly HOT and isn't noticably smoking, and makes it up to 95, then the rings should be fine.

Well I timed the ip and put the original injectors back in. I have a hell of a lot more power now. But I still have a rough idle and some white smoke. There is a little nailing going on. So before I go in anyfurther, I will focus on rebulding the injectors. Heres a video of it running.

Well got my new radiator today...boy its a nice one...and its a Behr. I cleaned out as much of the rusty colored coolant as I could but I will have to drain it again after some driving. I also changed the filter and fluid on the trans...didn't drain the torque converter though. The fluid was still nice and pink from the rebuild. I also changed the shift bushings. Now all I need to do is get the injectors, but at least its now safe to go on trips with...the whole told of the old radiator was about to separate. Yesterday I got a working speedo put in it...but managed to brake the clear plastic housing on the instrument cluster...still mad at myself

Sad they replace all the bushings but one in the shifter...half as job people lol

Well she's still alive. She has survived have 3 windows busted out, 2 slashed tires and being flooded by a couple of storms.

She will still get up there, if I have a hill in front of me.

I have made 3 trips totaling over 3000 miles, she's burning more oil then I like.....don't even want to know the compression numbers...

Me and her have a lot in common so I wouldn't trade her for the world. Like me she'll be around till she can't clatter anymore.

I just wish she wouldn't draw blood from me, every time I try to fix her
