EVEN BIGGER UV 51-LED flashlight



Apparently it's OK to leave this stuff in the oil and coolant. I really don't want to put it in my coolant if I don't have to. Tomorrow I'll check if BMW coolant naturally glows or has some kind of dye in it?

I read some engine oils come with UV dye in it already. That's interesting. Never thought to try this stuff out.
Its perfectly fine to leave that dye in fluids. You won't ever be able to get it all out, no matter how many time you flush.

If new oil has a greenish or yellowish haze to it, it has dye in it.

We use dyes like that all the time at my work. They make them for everything. We use a 150w UV light, but most of the time you can see it without using it.

water inside the alternator won't hurt it

Tire piece came flying towards me out of nowhere on the interstate, couldnt avoid it. Hit it with the license plate and the bumper. Why are there so many burst tire pieces on the interstate. That too in the middle of the city, what are DOT doing?
Casuality: plastic piece on front bumper and crumpled license plate.
At least the front plate saved the bumper and other parts. But I am still pissed.

Now any one have #2 on the following picture for the preface coupe?

Part #51118225599

The "egg yolk" is precious in my site. I wouldn't have it any other way. It looks like full quality. Couldn't pay me to put in clear bulbs. Save your money and have a platinum plus premium look:

I gotta save for new headlights to begin with before I worry about bulbs lol. Now that I'm 99% caught up on maintenance, those are the next on the to-do list. Should probably figure out which I want...

Made a u-turn yesterday while driving in the city and my dumbass didn't realize how close I was to the curb (ironically enough, as I'm one of the most cautious people I know when it comes to that), resulting in scraping my bumper (getting an M-Tech II in the next two or so months, OEM coupe bumper was scratched and chipped to hell previously thanks to the PO so I never really took a ton of pride in it to begin with) and having the passenger side front fender liner pop off. The ambient temperature sensor went unharmed, though, which is good. Tried finding a way to put the fender lining back on today, but it was too messed up to begin with (the scraping and popping off just capitalized on the damage), so I just placed an order for a replacement via rockauto.

Are you serious? If you are buying parts and stuff for your car at Dollar General you would be better off just driving it off a cliff now...

Quick question. I think my mechanic screwed up when putting on my headers. He may have mixed post and pre cat sensors. It runs perfect about 1k Rpms but when I'm at a stop for a bit it idles like crap. Any suggestions?

Not sure if I should switch both sides or just one at a time?
