Looks great. Do you happen to have the plug part numbers? I need some too. Thanks -
Happy to report that the unexpected battery compartment/tray rust project is now complete. Using a combination of wire brushes, wire wheels, roloc abrasive discs, sand paper, dremel grinding bits, POR-15 starter kit, Rust-Oleum Coastal Grey Satin Protective Enamel and patience, I was able to achieve this final result (with brand new OEM battery tray installed):
I just need to add the 2 plugs (the original ones I ordered were the wrong size, so new ones should be arriving today) and this project will be 100% complete and in the rear-view!
Pretty pumped that the Coastal Grey Rust-Oleum Satin Protective Enamel topcoat did a fairly good job of matching the existing grey in that area! Again, NOBODY will ever see this, so it was more for me, but I'm happy with how it came out. Here are some progress shots I took (excuse the crappy lighting) along the way:

Now that my FCP order arrived, I got to work on the battery compartment. After removing the black tray (but before cleaning), this is how things looked:
After vacuuming up the area, then following with some all-purpose cleaner and towels, this is how it currently looks:
I'm debating next steps now. Leave it, as is, or get rid of ALL rust.Leave a comment:

Continued the Spring of Service by flushing the brake fluid and replacing with Pentosin Super DOT 4 fluid.
Also removed the front lip to re-fit it better, as I was never 100% happy with how I installed it.
While the wheels were off for the brake fluid flush, I took that opportunity to try and bring some life back to the fender liners. Horrible lighting led to some crap photo quality, but you get the idea.
Before:
After:
I used Adam's Rubber & Tire Cleaner along with a tuff shine tire brush, followed up by Meguiar's M39 Mirror Glaze Heavy Duty Vinyl Cleaner and the tuff shine tire brush. Wiped off with clean microfiber towels, then applied Solution Finish, waited roughly 2 minutes to let it set, then wiped off with microfiber towels. Pretty happy with how they turned out.
Next up is getting my battery tray/compartment squared away. My order from FCP should arrive in the next couple of days, so I'll remove the battery and existing tray and start cleaning out that area to see what I'm really working with.

I ended up ordering a new bracket, among other things, from FCP. Should be here in the next few days, so I'll remove the battery and the existing bracket and get that all cleaned up and ready for when the new parts show up. Thanks!Originally posted by robgill View PostLeave a comment:

It’s pretty easy to pull that entire black bracket from the tray and clean up any rust in there. Then hit it with some converter and paint.
For the plug if you measure the size it’s a lot easier to try and match it up in RealOEM.Leave a comment:

Decided to yank the aFe stage 2 intake out of my M3 while I await the arrival of the Karbonius CSL style intake. Gives me a chance to sell the aFe and also get a good look at what I may need to replace in the engine bay while I'm in there. I have a For Sale thread if anyone's interested in it.
I still need to do the brake fluid and start on the cooling system, finding time is the issue right now. Maybe tomorrow night. Cheers!

While swapping in a new Champion H5 battery over the weekend, I got a real good look at my battery tray. Should I be at all concerned with the current look of this area, or is this par for the course? Wondering if I should look into any sort of rust treatment/prevention or leave it, as is?
Also, unsure what my options are with that hole. Is this hole a result of doing what post #15 from this thread says? And if so, does that mean I can plug that up with the plug also referenced in post #15 (#41007140847)?
Thanks in advance!

Went away to NH over the weekend for a little birthday getaway (sans kids), so the boys were very happy to see mom and dad when we picked them up from my parents on Sunday. My oldest wanted to sit in the M340i driver seat, so I happily obliged...then the youngest wanted to sit front passenger:
As for yesterday, I had taken Friday and Monday off, so my wife brought the kids to the playground and as an additional birthday gift, gave me an uninterrupted garage day. So I got to working on the M3. Unfortunately, I had taken a few spills on Saturday while snowboarding (mind you, I hadn't been in about 7 or 8 years), so I'm pretty beat up and moving slower than normal.
I did manage to flush diff fluid and trans fluid, and install new fill/drain plugs for both, as well. I am LOVING these new flat bottom jack stands:
Starting pile:
Took this opportunity to clean up some of the underbody plastics:
This is what's left to do (at least, until the intake arrives!!!):
And stored for the evening:
Going to leave it up on jackstands as I plan to start addressing the cooling system hopefully tomorrow. And I still need to flush the brake fluid. I want to remove the aFe intake so I can get that sold, but debating on waiting in case I need to move the car in/out of the garage in the meantime. I suppose I can reinstall the OEM intake for the time being...we shall see.
Very happy to be knocking these maintenance items off my To Do list and updating my spreadsheet with this info. I try to document ANY modification/service item that I perform to all my vehicles.
Stay tuned for more. Hoping to speak to the plumber in the next week or so to schedule a day for him to hook up the garage sink to my existing lines/drain pipes. Gonna be nice to be able to wash my hands BEFORE going in the house and making a mess of things.
Cheers!Leave a comment:
