Hello guys, this is my first post to the community!
About six years ago, when I was 14, I gave my mom $1,000 to find me a first car. She picked me up from school in a vintage "baby blue benz" - as I call it. I absolutely lost it and fell in love with european cars instantly.
After weeks of searching for the best mechanic we could, we finally found a Russian gentleman that worked for Mercedes-Benz of USA building AMG engines, and now runs his own shop (works alone) with his wife.
Just a few months ago I took him up an a great opportunity - to work along side him! I am now working with him several days a week, before my evening college classes. I can't even put into words the amount of information I have soaked up in the past several weeks. It's just me and him - and we get along great!
I have a couple simple questions:
1: He has been telling me literally every day I show up that I need to put some sort of additive in my fuel tank every time I fill up. He always makes jokes about how bad he feels for my fuel pump, and all the mechanical parts that are being destroyed by low grade diesel. I feel the need to take this seriously, because I remember buying the last OEM fuel pump in my area/state/country - I forget.
2: I recently replaced my motor mounts which reduced the shaking by 90%, but I still notice a bit of a shake (my mom drives a 1978 300D, the W123, and it's literally silent and still in the cabin compared to mine). My boss tells me this is most likely due to my injectors, since my motor mounts are brand new OEM. He gave me a special injector cleaner from Germany and told me to fill up a tank with it and drive 2-3 hours straight at 60mph. Still trying to find an excuse to make a trip from San Diego to Santa Barbara...anyway, what do you guys think? I'm sure its worth a try, but I would like to get your opinions before I put that kind of miles on it and burn that much fuel (cash).
3: Lastly...as clean as my paint is, there is ONE spot at the very very back of the driver side, the very bottom panel behind the rear tire. It's nearly rusted through - could probably break through with my thumb if I really tried. Again, my boss suggests we find that panel off a donor and literally just weld it on top, and sand it flush. I have seen his welding work on his personal vehicles, and where there was two layers of metal he had three. It looked as though nothing had happened. Though, I am worried finding a panel might prove to be nearly impossible. Anyone have luck doing it with bondo?
Anything is much appreciated! Hope this post wasn't too grueling!
