Front fenders from any 123 will fit. Doors, rear fenders, coupe specific.

I imagine trim parts too. Sun visors, coupe specific.

Turbos were added in 1982 on coupes and sedans, 1981 on wagons.

thanks by the way! i love her to death, but when the ol lady is getting 25+mpg in a turbo diesel and im lagging behind in big ol betsy getting 15mpg non turbo... so it was time for me to get one. and let ol betsy get boosted. she was right for what i needed at the time, something diesel that could handle all the kids and me and the ol lady, comfortably, get decent mpg's and haul anything i could trade for or buy. which i do a lot. now i need something to get me back and forth to work while i put turbos on the truck. and i refuse to buy another gasser. all i want to own is diesel, IDI diesels to be specific. they are stupid simple, and im pretty stupid. lol. and if you buy parts cars/trucks you will always have a running one.

You're going to love this car once you get it sorted out .

You've not yet mentioned adjusting the valves (takes two open ended 14MM wrenches heated and bent with the gas torch) , that ALWAYS needs doing when you buy one and every year or less after .

I'm on my third 300CD now , the NA ones are kinda sluggish , my current one is an '84 , the turbo makes them into fun rally cars .

Cleaning the fuel system (Diesel Purge) , adjusting the valves and replacing wonky hoses will prolly make the current engine run sweet .

well im sure once its lined out and a new color, ( i may wash and buff it and see how it looks). i will love it. well i already do love it. i have been driving it as much as i can. i even went looking to hook up the waste oil kit. and it was just un hooked from the battery, hooked up and switch flipped it worked! while its not near as impressive on wvo it does run and will be nice for long trips. or when im broke. i plan to order a couple valve cover gaskets, tranny pan gaskets, tranny filters, oil filters and fuel filters. i want to adjust/check the valves. do a compression test, seafoam everything! check breaks, coolant. and anything else i can afford this next pay check.

Seafoam? Really?

1911diesel · #51 04-30-2013, 08:57 PM

yes seafoam in the crank case, tranny, for diesel purge, and sometimes just in the fuel. why have you had any bad luck with seafoam?

Phillytwotank · #52 04-30-2013, 09:09 PM

Some people swear by it I guess. Personally never used it. What would you say it does for it?

1911diesel · #53 04-30-2013, 09:58 PM

well with the tranny tune, i have had trannys stop slipping, only if it was just slipping a little during shifting. you can tell the difference right off the bat in the crank case. when you change the oil it will break up all the gunk in your crank case and if you look at the oil that comes out youll see. the engine will just sound better. for a diesel purge, i have had great results. in the vacuum system of gassers, great results. its not a miracle worker, but it does do what they say it does. and with regular usage, i have had super clean oil and great running engines. so ill keep using it. do as you wish. its your money.

Phillytwotank · #54 04-30-2013, 10:09 PM

Don't get me wrong... I'm not knockin' it. I'm just wondering for your first hand account of your experience with using it in benzs.

1911diesel · #55 04-30-2013, 10:18 PM

honestly we have seafoamed my buddies 84 300d and it shifted better, even with a vacuum leak. did a purge to it and did an oil change(some in the crank case before change) to it last year. we have also tried it on the 82's tranny but it was too far gone. and a purge and oil change, it started leaking a little more but thats just because the gunk that was plugging a hole came free, and its another gasket that needs replaced before that engine is put back into daily service. i havent changed his oil recently, but his car still sounds good to me. and so does the 82 sd just a slipping tranny and some oil leaks.( valve cover and turbo grommet on the oil pan) i think we are all going to do valve adjustment/check and valve cover gaskets the same time. and proly the seafoam all the way around. i buy it by the gallon at rual king. i have used it on plenty of gassers and my idi truck and 2 benzs i do it to everything i buy, the first fluids change, every time. it always seems to make a difference. so i will continue to do it. until it seems like a waste of money, this cheap a$$ will spend his money on it.

Yes , Seafoam works ! I've been using it for DECADES .

A warning about WVO ~ to do it right , takes a huge amount of both time and labor ~ no way around it . Plus of course , that big greasy drum in your garage that sweats oily goo 24/7 .

I got my '84 300CD because some stupid hippies in Sta. Monica ran it on poorly filtered WVO until it killed the engine ~ I had to re sleeve the cylinder block and replace the pistons due to the deep longitudal grooves gouged in the cylinders ~ WVO cokes up in the ring lands and it's much harder than the pistons or cylinders .

Many fools refuse to admit this simple truth but it is so .

Be very aware of the pitfalls before you go down this road , many good Diesels have been killed to death by WVO .

1911diesel · #57 05-01-2013, 05:22 PM

yeah, the oil that came with the car seemed to be pretty clean, almost like new oil. but im not sure that there wasnt a little water in it somewhere. ran great the other day but now acting like water in the line. i ran WMO for about 2 years in my idi and in my buddies 300d. but oil sources are drying up. my $ 1.00 pr gallon bids are getting beat by $1.5 and $2.00 bids! so ill just buy diesel. like you said it takes time and labor. and with WMO it gets nasty quick. i still collect all i can, if and when i can. now it just gets mixed with diesel to off set the overall cost. mainly saved for road trips where i would be digging for cash anyways. i still think i will rip out the oil kit. i like having a full trunk. and the tank isnt bolted down

so it ends up everywhere right at the moment.(not the oil the tank) i do like driving for free tho. but i have heard worse things about WVO over WMO. this is the first time i have ever ran WVO, nothing bad yet, but only a couple miles. i have over 3k on WMO and didnt run into problems until i got to the bottom of a 275 gallon tank i got that was used by a place that serviced ambulances. i think i got into some axle grease. even the pump i used for transfers was having a hard time. lol it ended up being hard on a set of injectors and since i had spare parts (ip and injectors) i just changed everything turned the pump up a little, and timed it. i still burn some oil. just not much anymore.

it was my impression that the "coke" that builds up on the rings and pistons is due to, lacking on filtering, and low engine temps, (or oil temps before combustion). like i said this is my first time burning WVO. but i did do a lot of research before burning WMO and found it was the better choice for me. wouldnt higher EGTs also help with "coking"? just a thought.

Not a good way to go.

Isn't the smoothness of the 722.3 something else that gets bragged about?

Yes , all this and more ~ that fact that you even tried to use the sludge in the bottom of the barrel points out my basic truth .

WVO / WMO IS NOT " FREE " ! it is a trade off between your time and the cost of Dino Diesel .

Sooner or later you'll get tired of doing it right and the engine will suffer , the car will get junked .

BTW : WMO is *very* acidic and corrodes both the injectors and the IP .

Both of these fuels damage the engine slowly so over time it's like the proverbial frog in a kettle . the heat rises so slowly by the time the problem can't be ignored , it's too tale , you've ruined yet another fine old Diesel .

It's not pretty but them's the facts , jack .
