Hi, I know these are hard to come by but I figured it wouldn't hurt to ask. I'm looking for a non-turbo cylinder head for my 1979 W123 300TD Euro wagon that is not cracked and is affordable. My wagon currently has a cylinder head from a sedan. As many of you know, the sedan head does not have the port for the SLS pump, which means the SLS system on my wagon has been deleted. The goal is to get the correct cylinder head and slowly work towards restoring the SLS system. I just recently purchased the correct head for a reasonable price ($300) just to find out that the head was cracked and useless. Bummer to say the least. There are two options that will work for my wagon, the original head that came with my wagon, with the old loop style glow plugs, the part number is 6170103120. The other option is the head that came out right after this one, it uses the later style glow plugs, the part number for this head is 6170106320. I would prefer the second one with the later style glow plug set up, but I would consider either one since they are both hard to come by. Both of these heads are for a NON-TURBO engine and they are both specific for the wagon and have the SLS port. This part is very important.. the head needs to be magna-flux tested and cannot be cracked!! Of course, I'm hoping to find one that is affordable and local would be great too. I'm in the Los Angeles area. I'm not opposed to having it shipped if it can be shipped for an affordable price, but I doubt that's possible. I know I'm asking a lot and it's a long shot but you never know. Also worth noting, the cracked head I just purchased, with the part #6170103120, also had the number 6176160407 stamped on the front of it. That number is NOT the part number but some sort of stamp to show when it was manufactured, if I am remembering that correctly? Before anyone sends me cylinder heads for $1000's of dollars, let me just say that I can't afford that. It's no offense to the sellers and I'm not saying what you have isn't worth it or that you can't get that price, I'm simply being honest and letting you know I can't afford it. I've also been told that a turbo wagon head would work with some modifications but I would like to avoid that if possible, at least for now. Yes, I'm looking for a needle in a haystack, for cheap.

I have one I would sell CHEAP with small hairline cracks in the head. You can have the cracks repaired by a competent cylinder head shop who can stitch the cracks and then pressure test it for leaks, but not all shops are capable of this task.

Good head will be $$$$

Well, the one I just bought has hairline cracks so if I wanted to go down that road I could do it with the cracked head I already bought. I know finding this very specific, uncracked head for cheap is highly unlikely but I figured I would at least ask around before resorting to plan B or C. Also, the sedan cylinder head I have in my wagon is working fine for now so I think I would only go through this whole process if I find exactly what I'm looking for. If I don't, then I'll probably just live with the sedan head and the conventional rear suspension that's in it right now. Perhaps it's a pipe dream but I'm sure we've all found parts over the years that we once thought would be impossible to find.

I know it's not original, but since you're running a sedan motor in your wagon already, you can get an electric pump and run the SLS off that....and for way less than it costs to obtain a crack-free head.

I have seen a wagon do that with a mini cooper pump. You run a sedan motor and then the Mini-cooper electric pump for the SLS and now you have working SLS system. That is the cheapest way to go if funds are the primary concern, and not trying to restore a low mile wagon.

That's good to know, thanks for the info. I'll put this option in the plan B folder for now. After I tire myself out trying to find the correct head, I'll probably start looking into these other options, perhaps. Thanks again!
