Here is what is on my list of winter projects--
1) Wheels. Source a complete set, (I've got 2 so far) of the 6 x 14 aluminum wheels that Jim Villers turned us on to. Once I get all 4, then they need to be cosmetically repaired, and finally, powder coated.
2) Finish up the horn project. Those who came to Joe's in July might have seen my "restored" horns. All the parts were there but not completely assembled. I need to assemble them all, and then document it for the anyone else to do.
3) Seats. I plan on taking the seats apart, repairing and or replacing or otherwise improving the spring steel "basket"; adding additional support to provide a firmer feel, and then putting it all together, and documenting it of course. I need to make some calls and call in some favors here; Lear Corporation and Johnson Controls, two of the largest automotive seat manufacturers are in my neighborhood. Certainly they have prototype labs, and I just have to have some help!
What's on your list?

Mike -- I think it’s going to be a long winter in Idaho…
Per your request, here’s some of the things currently on our list:
- The new engine from Metric is smoking pretty badly when I decelerate. We’ll identify and fix that. Have already spoken with Mike Elias at Metric…great guy!
- Have a rebuild done on the fuel injection pump…it’s never been touched before.
- Clean up the engine compartment…it would not win any sort of beauty contest now (not that I’ll ever enter a contest…I’m just persnickety about such things).
- Continue on with engine cooling improvement efforts / experiments. I’m serious about taking the car to Death Valley in 120+ temp and expecting it to hold temp. during prolonged periods of idle with the A/C blowing ice cubes. (I know, I know…it’s supposed to be impossible).
- Will probably switch to a 3.27 rear-end. (have another trick up our sleeve, which we may also try just for fun).
- Change out existing high-volume Spal blower in Frigiking A/C to an even higher volume unit.
- Replace all brake lines with SS tubing.
- Go to progressive rate springs … maybe different shocks … perhaps a slightly larger anti-sway bar. (Tom S, thank you very much for the inspiration!!)
- Probably go to bigger alum. wheels… try different tires for optimal configuration of performance & comfort (while still maintaining the orig. look of painted wheel covers and white wall tires).
- Check out the possibility of adding a turbo… (probably a longer-term activity though)
- Have the hood repainted. (too many dings from all the recent work).
- Existing paint is good, but has micro-scratches…probably caused by me using the California Car Duster. Have a good polish job done to remove those irritating “spider webs”.
- Bumpers, grill pieces, etc. all need re-chroming…will probably have this done.
- Maybe try a set of European headlights.
- Have new custom soft top made … will use the CLK 500 cabriolet as the inspirational model for this activity.
- Have soft luggage pieces made out of matching leather to fit newly modified trunk.

I'm considering removing the oil pan from the engine. Then I would determine where the oil level is with the car at rest. Then I'd find a spot where there is a little bit of oil spray with the engine running. Not too much - just right. Then I'd drill a little hole so it leaks a little. I'm just not comfortable knowing that there is oil in the engine, but no oil leaks to show for it.

Oops! I spoke too soon: I found two drops of oil and some antifreeze on the garage floor!

- Maybe this will be the year for those new MB tex seat covers.
- The car could use a few new wheels (I suspect I have one or more slightly bent rims). Maybe I will go on that aluminum-wheel-quest.
- Replacing the timing chain and checking the cam timing.
- Fiddling with the engine tuning (ignition, air/fuel etc).
- Checking the 3-position solenoid operation (the activating microswitch is disconnected currently because otherwise the car does not shift properly).
- organizing and cleaning up the garage!

[:0]I am not going to do anymore suspension work!
I will do a tranny service and change the fluid and filter. This will be the 1st time that I have done this...
Otherwise simply drive the car... winters in Memphis are pretty nice. We can have one day of cold weather and the next warm and sunny... 8)

Cees: If your throttle position switch is disconnected, how does the 3-position solenoid know that you have taken your foot off the gas pedal? Normally, the closing of that switch makes the transmission shift up. Is it now just the vacuum that makes it shift? At one time, I recall, you thought that the microswitch at the firewall was part of the transmission control. But that switch, I discovered, engages the fuel shut-off solenoid on my injection pump. The switch on the outboard side of the throttle plate is the one which signals to the transmission that the throttle is closed. You also said that your transmission shifts very smooth from 2 to 3. Mine shifts smooth most of the time-after adjustments, but sometimes it is still harsh. (Only the 2-3 shift is harsh). I am comparing it to my Toyota. You also said, that your transmission shifts down under increasing load, like modern transmissions do (because of decreasing vacuum). Mine does not do that: I have to use "kick down" or use the shift lever. If your transmission shifts fine, and the 3-position solenoid is not working, maybe we should disconnect it?

Hi engineer:
"If your throttle position switch is disconnected, how does the 3-position solenoid know that you have taken your foot off the gas pedal? Normally, the closing of that switch makes the transmission shift up."
I think something is amiss with the wiring, that puts the 3-position switch in the second position at all times, not just when the car is put in gear. So it does not need the switch anymore for that actuation.
"Is it now just the vacuum that makes it shift? At one time, I recall, you thought that the microswitch at the firewall was part of the transmission control. But that switch, I discovered, engages the fuel shut-off solenoid on my injection pump. The switch on the outboard side of the throttle plate is the one which signals to the transmission that the throttle is closed."
I have no microswitch at the throttle plate, AND I also do not have a fuel cutoff solenoid on the FI pump. So the switch, when it was hooked up (until a garagist unhooked it years ago), did in fact control the 3-position solenoid
"You also said that your transmission shifts very smooth from 2 to 3. Mine shifts smooth most of the time-after adjustments, but sometimes it is still harsh. (Only the 2-3 shift is harsh). I am comparing it to my Toyota."
Yes the trans shifts smoothly 4 out of every 5 shifts I would say. But that seems to have more to do with vacuum settings (and maybe a properly functioning 3-position switch).
"You also said, that your transmission shifts down under increasing load, like modern transmissions do (because of decreasing vacuum). Mine does not do that: I have to use "kick down" or use the shift lever. If your transmission shifts fine, and the 3-position solenoid is not working, maybe we should disconnect it?"
I am 75% sure that my car used to downshift when I applied more throttle but before pressing it all the way to actuate the kick-down switch. However, Joe Alexander posted yesterday that our transmissions are not supposed to do that. And someone else reported that their car downshifts when more throttle is applied. At this point, I think I will only find out on my car through a lot of fiddling with wiring and settings.

Hi Cees: That was a quick reply: Don't you go to bed at 10PM like us regular folks? I guess, the switch at the firewall can be used to signal the 3-way solenoid that the throttle is closed and then you don't need the switch on the throttle plate. Finding the correct wires may be difficult. My car has the R20y injection pump and, with it, comes the fuel shut-off solenoid. It works well. I have filed the contacts of the speed relay and have -temporarily- a test light connected to burn when the solenoid is energized. The book says that the shifting of the automatic is depending on speed and vacuum. It is not supposed to downshift when you drive up a hill and the engine has insufficient torque and drops in RPM, until your speed diminishes to the shift point. Long before that I shift down manually. Data are given at http://www.pagode.info/21.htm But I have driven one Pagoda that shifted smooth all the time: It may be that someone imstalled a different transmission. I looked for a model or s/n but couldn't find one. It was somewhat difficult because I couldn't jack up the car and the owner wasn't helpful. Mine is about like yours: It shifts nice four out of five times. I have to educate myself more on the transmission.
This is the switch on my car which, when closed, energizes the fuel cut-off solenoid: (several other switches must also be closed)

My plans involve overhauling the 4-speed gearbox, and replacing the alloy wheels with good old steel wheels and hubcaps, repainted but suitably used-looking to match rest of car...
Engineer,
I like your project, would like to suggest you maybe install a small valve to control the leakage rate. My understanding of the conditions inside the crankcase is that it's a pretty thick rapidly swirling fog of oil droplets in there when the engine is running, so any hole you drill will probably leak quite a bit. I guess you could start with a very small hole and work up, too, but a valve seems more elegant.

My list is surprisingly short this year. Oh believe me I could find some biggies to tackle (leaks here and there, paint & bodywork, etc) -- but just am not going to do it. Unlike most of yours, my car is nowhere near perfection. And since I am not a mechanic, the idea of tackling anything major means sending it out on a fishing expedition. Not going to until I have to.
Over time, I have done a lot to get it to a decent old driver -- and am happy to be there! So my list at the moment is:
Change the oil & filter
Quick Detail it often
Drive it whenever the sun is out!

My car has been running great since the electronic ignition conversion. It has been so much fun driving it that it is hard to put it up for a long project. Like James, mine is a decent driver and it's sole purpose is to provide me with driving enjoyment. One big project I have been contemplating is to repair the heater and A/C. No water is currently flowing through the heater coil (not connect) and not sure what is the condition of the coil. The A/C is not charged.
Is there a way to test the coil integrity through the inlet and outlet pipe opening without having actual water flowing through it? Any suggestion would be welcome.

<<Is there a way to test the coil integrity through the inlet and outlet pipe opening without having actual water flowing through it? Any suggestion would be welcome.>>
Here is am old trick I have used . This will test integrity for leaks ,but not flow..
Cut a skinny bicycle tube in 1/2 .. clamp each end to the inlet/outlet. Pump some air into the tube through the valve stem .. let it sit for a while .. watch for holding pressure. You do not need a gauge, just watch the tube size for deflation....
You can also take some hair shampoo and warm H20 and whip it up with a paint brush . Now , with air still in the heater core , pop the inspection cap at the heater valve and paint the suds heavy down in the hole .. if it is the O ring that is leaking by , it will blow bubbles from the shampoo. Many times heater cores are by-passed b/c they are incorrectly diagnosed as bad/leaking core , when the correct failure is just a .50 cent O ring at the valve...
A little crude, but it works......................

Tom,
Gorgeous car. I can't wait to see it finished. So what's your secret on the firewall insulation? Looks like it's new, but it appears to be the original pattern.
Do tell.

Thank you for the tips. It looks simple enough that I am definitely going to give it a try. I would rather not have the pull the core if it is not leaking.

Ok. After reading my earlier post a couple times -- as well as others, I realize it was a cop out... So I went to garage, pencil in hand. I now have a list of 15 things that I might do over the Holidays! Thanks a lot guys!
PS Nice photos Tom -- I can only dream to do something like that with mine...

Have the car repainted. 8) The time involved is up to 3 months including removing current paint and taking care of the random dings. I plan on driving the next couple of months. (Great weather here in October and November). I'm planning on beginning to remove the chrome, etc around 12/1 to get ready.
While dismantling to paint I'll also take the opportunity to pull the AC to get at my bypassed heater core and have addressed. I figure this way I get to strip the dash at the same time.
.....Guess it'll be spring once I get to put it back together.

Hey Guys,
I must say that Tom's car went through a very impressive resto. Good going Tom. As for me, this winter I am having the same thing done to my car as Tom's. Expect my car is going to Pakistan for a ground up. The reasons for this are, cheap labour; lots of domestic help; fathers friend who owns a Car manufacturing plant; peanuts for rechroming; peanuts for other small things, (and when I say peanuts that means that to cut new keys and tumblers to match the ones already on my gas cap, will cost me at best USD $5-10)and my own leather business. I am also planning to make fitted luggage for my car and maybe who knows if it works out then start a production line for all u guys. Please wish me luck. Also I would like to add here that despite the fact that I am taking my car to Pakistan, I know that I would have wanted nothing more, mechnically, than to have my entire engine rebuilt by Dr. Benz.
Anyways guys please wish me luck and I will still be using this site to explain several things to guys over there. Thanks in advance!
Regards,
H

Tom, that restoration looks great. Can't wait to see the finished product -- who is doing the work for you?
Question - can you give any details on how the A/C unit restored? That is on my "to-do" list but I'm not sure where to begin. My unit is out of the car but cosmentically it looks like the your "before" picture.

This may seem bass-ackwards, but I think I will try to drive mine! We don't get much snow and my car doesn't have A/C, so summers here in SE Virginia can be tough. I have been working my tail off in my relatively cool garage since late June taking car of some long standing issues. Now is the time to see how it all comes together.

Disassembly is pretty straight forward. Refinish metal parts by stripping to bare metal and repaint. Have the condenser pressure tested then cleaned and straighten the fins. I used Dynamat inside (more effecient and cleaner than the foam rubber of the original ). The vents were cleaned and face plates were re-created by silk screening onto new aluminum plates and water jet cutting of holes. The plastic bezel was also cleaned and sprayed with flat black.

I plan to do a big project !
I am moving house next week, building a new house locally, but renting for a year ! The rented house does not have a garage or even enough driveway space for my 230SL so I decided to bite the bullet and do what I have put off for years !
I am going to replace the front wings, rear 1/4 panels, repair some dings in the door and boot lid, any other rust repairs and have the car repainted in its original colour which is DB050. The car currently is some MB shade of white which is lighter than it should be !
This car has rust in its wheel arches and headlamp buckets and along its extremities. I will be stripping the car of all its trim, chromework etc, and dropping it to my bodyshop where I expect it will stay for 6 months or so !
I'll miss it and miss driving it but it seems like a good time to kill two birds with one stone !
I will have lots of questions I am sure so I'm warning you all to lookout !!! [:p]
It seems like a lot of us are going through this process at the same time, maybe a communal (sp?) thread would be a good idea !

Ben in Ireland.
