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

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)
