1982 300D turn signal

I was merging onto the highway with my left turn signal on and about halfway into the merge the turn signal stopped working. The dash lights and the external lights don't flash anymore in either direction.

I don't know if its related but I replaced the voltage regulator and the battery the weekend before because it started to need a jump every morning.

Please give me some suggestions for starting to troubleshoot this issue.

85-300SD Battery Drains Dead Nightly?

I am baffled finding direction for a solution with problem. Every morning I need a jump start. I have a new Bosch battery purchased 30 days ago. Once charged it runs for the day. However, when I start the car throughout the day the driver front seat starts to move forward until the car slowly fires backup? This is recent situation and I have not made any significant changes to the 300SD that would affect this situation.

Need troubleshooting advice. Thanks for any guidance.

84 300SD weak ignition switch

I have an 84 300 SD with 279,000 miles. My wife has a key ring on the ignition key. After 28 years the weight has caused the ignition switch return spring to weaken to the point with just the key in the ignition alone it won't return to the II spot. My question is, is that spring that returns the switch to the run position in the key part of the lock itself or the is it part of the larger locking mechanism?

1986 300SDL hood spring?

I was driving down the street and my hood came unlatched and bent backward over the windshield. (I don't think I had it latched completely down.) I was able to stop and bend it back down, but the hood is dented and the driver's side (large) hood spring came loose.
How do I replace the spring? I am going to replace the hood (but have not yet.) will it be easier to do with the hood off? I barely get my hand down next to the fuse box say nothing of figure out how to stretch that spring into place. Is there a special tool for this job?

Thanks

1977 280e backfires through intake

My 1977 280e runs roughly. New fuel pump, fuel filter, the usual tune up. It is a little hard to start when cold or warm. It backfires out of the intake when you step on the throttle. I have disconnected the intake vacuum line and plugged it that leads to the cabin. The EGR valve has been plugged off as well. Most places I have read always say the backfire issue is almost always vacuum related in this car.I've checked all of the rubber vacuum connectors and they seem to be good and snug fitting.THe car idles at around 550 RPMs.

1986 300sdl fuel injector and compression testing question

First, I was removing my fuel injectors to do a compression test, I looked in each of the pre-chambers for oil and carbon (as instructed). I found what appears to be in inconsistency. when looking into my number 3 pre-chamber I see a normal appearing tip of the glow plug and another "thing"--it is bulbous in the middle and then thins out as it goes toward the ends of the chamber (on the "normal" five chambers. But in number 3, it appears that in just this chamber the part does NOT to extend all of the way through the chamber on both sides (only one side). Is this normal? what is this part? Should I be concerned? (i have a picture but i can't figure out how to load it into this text box)

Difference between turbo issues, ALDA issues and wastgate

I have a 1985 Turbo federal model...no particulate filter. I bought the turbo rebuild kit and tested the turbo beforehand. It only boosts to 7.5 psi without the installation of the kit (in summeer). I have not rebuilt the turbo yet. The car is extremely slow off the line and in cold weather....I can floor it for three minutes with no increase in RPM. (Some people even cut my block heater cord off because it smoked so much....as if that would stop me!)
