OK, the article is on a CSB LS V8, but it applies to all ICEs. I confess to old school ball honing, but that was 30 years ago...today is different, even on an E46 S54. Know what needs to be done! https://www.enginebuildermag.com/2023/01/honing-the-ls/

Hello everyone! I have finally decided to formally join the club. I have been a longtime reader of the forums starting 7 years ago with my first car; my 2002 BMW 325i M54. I learned that these really amazing machines will make you fall in love with automotives. Thanks to the support of this...

Hunting down confusing problem and need input, thanks in advance for your help. 05 M3 144K miles. Cylinder 6 misfire around 135K, replaced plugs and after a few thousand miles misfire came back so I replaced coils, problem went away again. Unrelated (or I thought so), spun a bearing and just...

Hey Everyone, I have been reading a lot of the different threads on the S54 Double VANOs system and there seems to be a wide variety of root causes to various error codes. One thing I am seeing most commonly is that the solenoids are prone to sticking/getting gummed up over time and a tell tail...

In a pickle. One of my cats is going on my stock US-spec E46 M3 and thus the inevitable "upgrade" to Euro-spec ensues. Issue I am having; while I got a Status Gruppe Section 1 with high-flow cats, I am unable to get the BMW stock Euro-spec headers until December (backorder everywhere). Ebay has...

I have a 2002 m3, for a few months I have been experiencing a loss of power and the fuel mixture at 15.4, I don't know if it is related, but I have changed the fuel pump, pressure regulator and injectors, and the car remains the same. Previously, my car had 288whp, now it does not exceed 230whp...

Returning member here and just wanted to re-introduce ourselves. We are a machine shop in Southern California and primarily make performance-oriented parts for E30, E36, E46, and other BMW/Mercedes chassis. This is our S54-powered E46 touring which is one of our personal favorite shop cars. We...

So, after a lot of hand-wringing, I finally decided to bite the bullet and get my rod bearings done at 167,000 miles on my 2004 M3 that I acquired from the previous single owner in April 2021. He never drove it hard, and when I asked him how often he redlined it, he told me "never" - I believe...

Have an issue with the car dying on idle. I can let it warm up to temps and it drives just perfect. However if im sitting at a red light for too long (at operating temps) it will intermittently stall on me. If im sitting in a drive thru it does the same. Usually after about 2min of sitting idle...

Hi there, My S54 is due for an oil change and I'm also about to replace my leaking valve cover gasket and was wondering if anyone had thoughts on the order of those two procedures. Any harm in doing the VCG replacement while there is no oil in the engine? I'm wondering if removing the valve...

Wanted to ask for advice as to which set of rod bearings should I buy. I was thinking ACL with extra clearance (0.001") for durability and affordability. Kindly share your thoughts. Best regards.

After 300 km of driving (Occasionally hard) I sent my oil to Blackstone labs and got the following result back. As you can see the lead is in 20 PPM only after 300km. Would like to hear your comments from anyone with experience. Should I drive the car? Or should I park it? PS -The...

Hi everyone, Simple question: Is Vanos of the same nature as rod bearings, meaning that when they go bad the entire engine can go bad? Or is this a job that I can do once they go bad? Kindly let me know your thoughts. Bests!

Hey folks! I have recently done quite a bit of work on my engine and got it all put back together! Now, I've come across this idle problem that I can not diagnose and have tried to research it to no avail. My hope is that someone has come across this issue before or will be able to help me...

I recently just finished rebuilding and turbocharging my s54 in my 2002 e46 m3 and i am looking for a solution for engine management. The first thing i looked at was the aem infinity for the e46 m3 but after contacting multiple distributors it seems like the jumper harness was discontinued...

Hi guys I’m not sure if this is the correct place for this post, let me know if it isn’t. I bought my first e46 m3 last year and the s54 started knocking due to rod bearings a month after owning it. I decided to remove the engine myself after never doing it and having it rebuilt here in Santa...

Hey guys, I’m new to the forums and I’ve been trying to figure out if my M3 has had the bearing recall done on it. Not on carfax (bearing recall isn’t listed), and bmw won’t give me that information on the VIN as it is private to the original owner. They just say it has no open safety recalls...
