So I pulled the engine from the 300SD, which is turbo. And the engine from the 77 300D, NA.
Got the engine somewhat clean, and went to swap the pan, because I was not going to add the turbo. to the 77.

Well... the pan will not fit. I do not know what do now. Give me your recommendations..

1) put the turbo engine in the 300D and just block off the oil return lines somehow. This was a good running engine.

2) the NA engine has a massive leak from the back, near the rear main seal. But it looked ok on the pan side. I have not removed the flywheel. Also this engine had low compression. But that may have been due to running WVO on what was mostly a single tank. It had compression around 100psi before I removed it. It would not start. And I still do not know where the oil is coming from. I sat the engine on the flywheel to remove the pan, and the flywheel was covered in oil before I got the pan loose, so It will still have that issue with the new seal just in the pan side.

3) throw in the towel, and get something different.

I would like to get the 300D running, as it is a very nice car inside, and body wise. But I am very frustrated right now. And do not know how to proceed.

All I have done is major repairs to cars for the last year. ARGH!@%T

thanks

I'm confused at what you wanted to do. Are you trying to put the turbo engine in the 300D that originally came with a NA, but planning on taking off the turbo? I don't understand why you wouldn't just put the good turbo motor into the 300D.

yes, that is what I was planning on doing. I did not plan on leaving the turbo on, because the turbo is in the way of the throttle, and as far as I know the rod to shift the trans. It is not vacuum, it is mechanical.

You should be able to get a throttle and cam cover lashup from a W116 300SD (turbo with the same series transmission). That's got to be a better solution than all the tinkering you are doing

Would the pan not fit b/c of the oil pump?


Since you have the pan off, and the engine out.... I would fix the seals on the engine you want to use.

What could it be other than the rear main seal (rope style)?

is this the engine that covered that trans in oil? 85 cali?

NA and turbo engines are remarkably different in many aspects. Can't imagine why youd want to take the turbo off.

my only reason to take the turbo off is because of the throttle issue.
I have no idea what to do about the throttle.
What parts would I need off of a W116? Would it work on a w123? All of the other cars I have are W126

The compression and valve overlap of the turbo engine are different because the 617.952 is designed to work w/boost. Seems you'd create fish out of water problems by deleting the turbo, not to mention performance and economy losses.

If you can't get set of linkages that accomodate the turbo, bodging one doesn't sound too hard, I'd look at what had to be done.

I hear that you want to keep the turbo tranny and engine together if you can.

www.kiva.org It's not like there's anything wrong with feeling good, is there?

The turbo 617 engine has a heavier crank and a larger oil capacity (7.0qt. vs. 8.5 qt.) among other differences. The lower oil pan on the 300D is 115 010 04 28 MY while the 300SD is 123 010 00 28 MY.

Why do you need to switch the oil pans?
You'd need the rod and linkage off a 116 which controls the transmission like your existing rods, except following a different route down to the transmission. I'm not sure the engine compartment of a 123 has enough space for the rod to follow the same route as it does in the 116. does anyone know for sure if it will fit?

The reason for the oil pan switch was because of the holes left in it by removing the turbo.
But it sounds like this just is not going to work.
The trans with the trubo can not be used because it is vacuum, and also electronic speed. Where the one from the NA is mechanical, on both.
I have placed the pans back on both engines. The NA has a new rear seal in the pan side.
IF I leave it on the flywheel, and put 1 gallon of oil in it, I should know if the leak is gone right? but no guarantee that it is fixed unless it is running.
Sounds like this was a bad idea from the start....

Another option is to use your 300SD engine along with its 722.303 transmission.

You would need to convert the speedometer drive to a mechanical gear using the tailplate from a 722.315 (300D turbo) transmission, and then get all the W123 linkages from a 300D turbo, and bring over your 300SD vacuum control valve etc.

But I see no reason why the bellcrank from a W116 would not work in a W123- it doesn't stick out into the chassis too far IIRC. Using this 722.1xx transmission behind a turbo engine might not be a good idea.

I was wondering if the bellcrank from the W116 might hit the firewall since there is more room in front of the firewall in a 116.
I agree that an NA transmission with a turbo engine might be problematic. I'd also try to use the turbo transmission. Even if it meant that I used a GPS instead of a speedometer.

I just looked at my 116 and 123. I don't think there's enough room between the transmission and transmission tunnel for the 116 transmission control rod to fit in a 123. That must be why MB went to a bowden cable.

So If I run the 722.1 Trans with a turbocharged engine, I will ruin the trans quickly due to the added power.
What will happen if I run the turbo engine, with no turbo, and the injection pump from the NA engine, and use the 722.1 trans? What if I swap the Cam on both engines? that would take care of the valve differences?
I am not following on changing the tail plate? is that something someone who sees the auto trans as a "black box" could do?
Any one have a good photo of the linkage on a 300D turbo?
thanks
