Here is an image of a 14 head, found it on Peach Parts in a search. Oh well, I wasn't sure I could get to it right away:

I would guess someone swapped a 3.0 into that car, so the injection pump may be for a 3.0 too. Easy to sell either way though.

Good thing, the cruise control servo and rods had already been taken.

Hmmm ... interesting. I don’t know where else to look for ID stamps on the block, I could look that up I guess. I got the IP off. They charged me 60 bucks for it. Good enough. That was some work. The center bolt is in a reverse thread, I got that out. The hard part was getting at a small bracket at the rear - that was my final sticking point gremlin. All kinds of stuff in the way.

I wish I’d brought a 4 and a 5mm Allen socket with me. Today was my second trip, I really wanted to get it out without going home for more tools.

They don’t let you bring a torch, although they were very slack about searching, I could’ve had one with me and they wouldn’t have seen it. They used to search your tools a lot more closely. Probably still doing a lot of places.

I used to have a small butane torch, really compact. I went to replace it about 10 years ago, couldn’t find it, I bought this type instead. Didn’t buy it from Walmart, this is the only link I could find with the model I have. Still pretty compact, would be kind of hard to smuggle in in my pocket though. I have a set of regular old L-shaped Allen wrenches, I got several of the little Allen head bolts out, but buggered the couple that I just could not get to break free. Flame would’ve helped I think. Didn’t think to bring any Kroll like substance.

Naïve me, I didn’t consider that a 350 with 250K might have needed an engine replacement. A 3.0 would be the more likely option, lot more of those in the world, and I’m guessing they don’t ship those crate engines anymore.

This one was not a spring chicken by some indications. Someone before me took out four of the injectors and left them. They all have the needle thing sticking out. I’m not sure the value of injectors that need rebuilding.

The injectors used in the head you showed a picture of from the junkyard are the "vertical" injectors. Same ones used in the OM61x engines. Not very valuable and extremely common. The ones worth pulling are the "inclined" or "oblique" injection ones from the 3.4L and late 2.5L engines. They're unique to those two engines and are extremely to obtain 2nd hand or rebuilt.

The ones that failed sometimes didn't even last 80k, so who knows. It's way more likely for someone to have replaced a more recently failed one with a 3.0 for sure.

Hopefully I didn’t waste my time entirely, not sure my buddy is going to want to buy it, although he is sort of a diesel Mercedes go-to guy.

Chalk this one up to experience. I should’ve known to examine the engine more closely. I didn’t even look at the head number until I was halfway into the job.

Speaking of numbers, there is an ID plate on the IP body. Oh my God it’s got a wealth of numbers on it. I just now did quite a bit of searching and can’t find any information on it, Lease not as specified by the number. Once site looked really promising, then I clicked and it said access was forbidden. Who knows.

Maybe someone here knows what to look for. There are also some stamped numbers that are hard to see.

I notice they looked a lot an awful lot like the ones I had in my hands not long ago from my ‘84 300D.

So maybe this owner was a cheapskate. No idea of course how many miles that motor has on it.

? I thought your Asian friend asked you to get it for him ? .

I'm a regular in junkyards every where I go and as a Journeyman Mechanic I can usually discern the good parts from the bad .

I stopped getting parts for others years ago when my back yard filled up with good parts guys decided not to pay for after I'd done the hard work of getting .

I'd think a good injection pump from a smasher might be able to resell for $100.....

He did ask me to get it, I suspect he'll want it anyway, but he was hoping it was from a 3.5. He didn't say anything about checking to see if it was indeed a 3.5 and I didn't think to look into it. I know that Diseasel300 has spoken of using an IP from a 3.5 in his now gone 300SDL, some modification IIRC so there are some differences. Beyond that I have no experience or knowledge of it. I'll take it over today and see what he says.

I have no way of knowing how good the pump is. The car was at least running before it was sent to the yard so there is at least that assurance.

The main differences in the 3.0 and 3.4 is the calibration of the torque capsule and the RPM limit on the governor. The 3.4 is tuned for better low-down grunt and has a much lower RPM power band than the 3.0 does. Running a 3.4 pump in a 3.0 just results in a lower RPM limit and less "top end" power. I wouldn't suggest running a 3.0 pump in a 3.4 without reducing the RPM limit, that engine didn't gain the nickname "rod bender" for no reason.

Excellent advice. I’ll forward that to him. He may think he knows it all already, but nobody does. Hell, I might even buy that car from him someday. He wanted this IP just to have a spare. He really likes the 603.

I just took it to his shop. He was ecstatic to get it, he took a photo of the number badge, and then took a photo of the same badge on the IP in his nicer 350SD, he said it’s the same numbers. We settled on 150 bucks, cost me 60, I’m OK with that. It was a hard 90 bucks, hot as hell, on the second day didn’t take enough water with me and I really struggled getting that bracket on the back off.

If I’d had a stubby 10 mm wrench, would’ve made life a lot easier. Heck, if I’d even brought my battery powered Makita angle grinder, I could’ve cut through one useless bracket to get it out of my way, AND cut an inch or two off of that wrench. When I got back to my car, I had two bottles that I had foolishly left inside, they were as hot as fresh tea, I practically chugged one of them I was so thirsty. I might have to be more careful next time. I’m not getting any younger, too much sun not enough water on a hot day could be a problem. You would have to see this yard, it’s huge and all the euro cars are in one far corner. More than a quarter-mile from the gate. And I had a horrible paranoia that if I went to get more water, I’d get back in time to see some other guy making off with the pump.
