My Slow Burn (E46 M3)

[eforty6_m3]

Much to my surprise, the CSL dipstick and tube did, in fact, arrive yesterday!



Yes, I'll have to remove a portion of the intake anytime I want to check the oil level, but it's really not that big a deal. 4 torx screws is all I need to remove, in addition to unclipping one hose fitting. And it's a MUCH cleaner solution than when I stuck the original dipstick behind the strut bar, as it was slightly rubbing against the intake.

Maybe if I get bored and come across a cheap, used dipstick from a part out or something, I'll try my hand at bending again. But this'll do for now!

As for the misfiring. Now that I was able to get the car all buttoned back up and running, she's definitely still misfiring, but seems to be a bit smoother than before. Codes were showing that only cylinder 1 was misfiring now, so looks like he new plugs addressed the other misfires. I swapped the coil from cylinder 1 to cylinder 2 (and vice versa), and sure enough, cylinder 2 started to misfire. Ding ding ding. Looks like I've got a bad coil and a new one already ordered from FCP that should be here by Friday. Hopefully that is all the old girl needs to get back on all 6 cylinders so I can hit up the Audrain Museum Cars and Coffee Sunday morning!

Stay tuned...

Car looks incredible man!

Regarding the dipstick mishap...lol, what did you use to make the bends? My Karb box is still in the box waiting for my car.....

Coming from you, that means a lot...thanks, man!! Saw the photos you posted recently after getting your car back from Rex and, WOW, she looks amazing!

🤣 I used a Klein Tools conduit/pipe bender that I picked up from Home Depot specifically for this reason. Ended up putting a bunch of kinks in it (whoops), but it was my first foray into bending pipe of any sort so figured I'd see what happened. It was a clusterf*ck, hahaha. Lesson learned.

Dude, here's what we're going to do. Ask Matt to fly me down there and I'll do the install (minus the ECU stuff!!) for you! 😎

Not being able to drive my car the last 9 days is KILLING ME, because the weather has been absolutely perfect driving weather.

The very next day, when returning from a market nearby, the car cut out on me and threw a check engine light when taking off from a red light. Seemed to not be running on all cylinders (sounded like a damn Subaru boxer engine), but luckily, I was able to drive it home as this happened about a mile from my house. Immediately checked for codes and found the following:





Hassan from HTE said it was most likely plugs or coils, and having never changed the plugs on the car in my ownership, I can only wonder if they're original or not. My mechanic neighbor also thought the plugs were the most likely culprit, noting the recent intake install and tune, and this was probably putting too much of a burden on worn out plugs. So I started the triage by replacing the plugs and, while I'd be shocked if they weren't THE single culprit, they were most definitely a large contributor...these things were toast:








Plugs were all swapped over the weekend, but while I was at it, I decided to try and properly bend the OEM dipstick. I learned a valuable lesson during this time: I don't know how to properly bend pipe. I massacred this thing! So I did what I should have done from the get-go and ordered the CSL dipstick and tube from ECS Tuning Sunday night. It's on the UPS truck today for delivery, which is very impressive (yes, I paid extra for 1 day shipping)!

So once the dipstick situation is taken care of, I can reinstall the Karb box and take this thing for a test run and see if the misfiring situation is addressed or not. If not, then time to move coils around and see if they're also a culprit. Fingers crossed it's just the plugs.

While I had the cabin filter housing out, I decided to throw some Solution Finish on the faded cover:

BEFORE




AFTER (much better!)








And lastly, my new vanity plates came in, after waiting pretty much the length of the pandemic for the MA RMV to allow them again:

Hood up after a quick rip through town, so couldn't help myself in getting some shots of the Karbonius box:










Was then able to squeeze in a wash last weekend:

That's not the kit's fault. You can buy the kit sans IAT:

I bought the full kit as the IAT option was good for me, personally.

I needed the whole kit, though, for the IAT. And since it said it worked with CSL style intakes, I just assumed (yep, my first mistake) it would work with my Karb box. Lesson learned.

It came with the wrong IAT. I guess their kit is meant for a stock car that you drill a hole and mount the IAT somewhere else.

Oh, right. Well it’s deceiving because if you look at the item on the website, it says that it works with CSL style intakes, specifically. Super deceiving.

Anyway, can’t remember if I posted this or not but they finally sent me the right one. When I decide to install it, I’ll have to have my car re-tuned so I’m not in a rush to do that just yet.

What issue is that?

A few days back, I replaced my side markers with some new OEM bits. Crazy the difference these little guys make when they aren't old and faded. Little by little, slowly getting my car refreshed.

[eforty6_m3]

I love that color so much

Thanks! It certainly wasn't my first choice, but it has really grown on me!

Great work on the install! What'd you use to trim that shroud? I should be doing my install this weekend, was probably just going to dremel it but feel like that will be super messy

Thanks, man! I used an oscillating multi-tool. Cut right through it like butter and easy to handle to ensure a clean cut.
