Dumb Question Thread - No Flaming Allowed

I keep seeing this product on our local CL: https://sfbay.craigslist.org/eby/pts...210048143.html

But I've never, to my knowledge at least, seen a E46 M3 with something like this installed. It's not quite a mudflap. Does anyone have experience with these? Why don't more people run them?

I actually run something line this (10x cheaper and not carbon fiber) on the front of my s2k. With a square setup the tires poke out quite a bit, so front fenders and doors get bombarded with rocks/dirt.

I feel like it's kinda love it/hate it look. Like you said, they are not quite mudflaps... but for me protecting the paint is more important.

Hey that's kinda cool. Maybe even just pop them on for track day or canyon runs?

Do you need to register the battery on these cars? Changing the specs to a light weight battery.

Nope

Thanks, I replaced the alternator and all the belts. When I test the battery using the OBD, it shows as 12.5V. It does take a long crank to start, when it does finally start up, the reading shows at 11.5 and then back to 12.0-12.3. Does that mean that battery is likely shot? I can't think of anything that would be wrong with the install of the alternator other than the positive cable nut on the alternator.

Here's a fun one. Has anybody experienced a sheared VANOS hub tab that didn't stick inside the oil pump disk and also missed the timing chain? Found that my hub tab is sheared but that tab is nowhere to be found. No indication that anything was wrong either. Everything sounded normal, no codes, etc.

I had the oil pan off maybe a month ago and haven't driven it a whole lot since. No piece of missing tab in there when it was off the car and I'd find it hard to believe that it would have failed the way it did without any indication of it.

I see a stock 05 radio for sale and it says Aux/MP3 available. Is that standard? His face looks the same as my radio without an obvious Aux input.

You can buy a $15 cable. Radios made after like September 2002 all are aux capable. They aren't pulling your leg. You have to plug it in and find a mounting point. It doesn't come from BMW with the cable.

Ok here is mine, anyone know what this hose is for the one beside the wiper washer? I filled the wiper washer and some fluids just come out from
that hose

Overflow- mine is still zip-tied and elevated higher than yours. Yours seems to be cut?

I think it's time for new battery - voltage before cranking the starter should be a tad over 13V on healthy battery.

Check the battery with a multimeter. Off, the battery should not drop below 12.45V. If it is, it isn't holding the charged or being charged. It should be like 13.5-14v on. This is at the battery, not through the computer.

Other than vibration at idle...any reason NOT to use poly for engine mounts, tranny mounts, diff bushings, etc? Been happy w/ my poly RTABs and tranny mounts and they've been in the car forever.....

I have Vibratecnics solid engine and tranny mounts, I love them, makes the car feel very raw and super reactive. The feel of the car once at speed is really nice, I am yet to do full subframe reinforcement, I think this sensation will improve greatly after as well.

HOWEVER, idle will sometimes drive you nuts, everything might rattle eventually. I have to find whats rattling and make it not rattle, that's sometimes a futile attempt.

Im not well versed on poly for mounts. Solid is a preference, def it is mine. OEM stock is great as well, driven cars with it, they feel like Cadillac's compared to mine lol.

Should have pointed out...I don’t sit at idle much. It’s usually highway miles for me (200K plus and counting!). Plus it’s a convertible so it’s got a bit more reinforcement built-in.

Going to tackle the engine mounts when I do the front suspension and we’ll see....
