Oh, sorry for the misunderstanding. Yes, you can add a thin film of RTV for a little added security, just don't go crazy with it. We added a thin film to Toyota2BMW's bracket, not a bead a thin film.

 

OK great, the reason why I ask is because I've been trying to research more about my car which I'm still fairly new too. But not new too working on my own cars, and in the past I've rebuild my own rotary motor and gain knowledge from other engine builders to sometimes ditch the oem gasket. Just use high temp oil resistance rtv in place the gaskets. So I'm just trying to apply the same concept if possible, and ask questions first before I shoot myself in the foot.

 

Questions are always good, better to ask even the most basic question than be faced with a bigger problem to fix later. I also have done at least some work to each of the cars I have owned (and quite a few that weren't mine), so yes, research and knowledge is key. LOL, this is the first car I didn't go out and immediately buy the Haynes or Chilton's manual for, there is so much info online there is no need when Google replaces even the best manuals.
(This forum helps a TON too, with guys like Joe [Rizbel] and others that do great DIYs)

 

I did my own work. The seal is not an o-ring, but it is not thin like a traditional gasket, and is made of a soft, rubber-like material. It fits into a groove in the alternator bracket and seals against a flat surface on the block.

 

Is this the right part? 2004-2005 BMW 545i Alternator Seal - Engine Electrical - Genuine 04-05 545i Alternator Seal - 17802-01131721 - PartsGeek

Looks like the same form and material from my old Honda valve cover gasket.

 

This is parts number of the seal 12317507806, but it is discontinued as I see from ECS tuning. But they have alternative seal, your seams OEM one.

 

7. Johnson rods
8. Frammis plate
9. Muffler bearings
10. Blinker fluid
I googled Johnson rods see what they are but still can't figure out what exactly are they and what they have to do with oil leak?
Frammis plate looks like related to automatic transmission?
I have my OEM muffler changed to RPI do I still have replace the muffler bearings and where exactly are the located?
What is the blinker fluid and also where is it located?
Forgive me for all this questions but I am trying to Learn more every time.

 

 

Why you just not explain it in simple words rather than whistling if you know it?

 

Most of those things are garage jokes - no such item.
