Dead Tranny? What to Check? (1981 300D)
I’m wondering if my automatic transmission in my ’81 300D W123 is completely dead or just needs some good diagnostics. I’m asking for help on what to check to conclude what needs to be replaced.

83 300 CDT 617 Turbo Overhaul
Section 1 Turbo Removal shows compressor bolt removal when hot except for two at 11 and 6 o'clock. With respect to the difficult to access 6 bolt, why wasn't it loosened before the compressor bolts?
Does the turbo drain pipe interfere with removal?
I would prefer to break the difficult turbo bolts before the compressor bolts.

84 300d License Plate Bolts
I am embarassed to ask this, but what size license plate bolts does the 123 chassis use to secure the rear license plate? The car came with 2, I lost one by trying to size it up in the store, now I have one plate on the car (in a 2 plate state) and only one bolt holding that one on at that.

1986 560SEL stalling out on kick-down
I recently bought a 1986 560SEL. The engine was rebuilt (completely) at 212,000. The transmission was serviced at 195,000. It sat dormant for 4.5 years because the original owner had the engine rebuilt ($2,300 worth) and the tranny started acting up. He got digusted and parked it. Took him 4.5 years to decide to sell it I guess. I bought it, found a disconnected vaccum line under the passenger side of the airbox and it ran GREAT for 3 weeks.
The only parts I replaced to get it running (and home) were the high-volume / low-pressure fuel pump and the fuel filter. The old (original pump) had black old-gas sludge in it. I know I need to clean the tank (I was just foolishly hoping to melt it out).

1987 300DT, Brake Dust Covers
What are the pros and cons of using "Kleen Wheels" brake dust covers to minimize the accumulation of brake dust on the exterior of wheels? Do the dust covers significantly, dangerously, reduce the cooling air flow to the brakes?

83 300td Stripped Hatch Struts
I was trying to replace my hatch shocks and stripped what i thought was a torx head.
Any ideas on how to remove the stripped bolt? Do i have to replace it with the same style bolt or is something from the hardware store ok?
Thanks for any advice!

'81 240 D, green vacuum line question
Used Mercedessource repair manuals and vacuum pump to find vacuum loss on green line going into firewall. Comment in manual suggests this is vacuum line to Climate Control. Not sure this car ('81 240D) has climate control.
Pulled instrument cluster and could see vac line going into upper center of dash. What does it connect to and where would I find it? I hate to start pulling the dash only to find it was a simple repair if I had just known where to look...
Thanks!
