I have seen both options recommended, but usually via old threads. Are the new design Mahle rings ok? Are they a different part number? Or is the M52 hybrid solution the right way to go?

As the title says, should I be rebuilding the calipers as part of regular maintenance if there is no signs of sticking or leaking? This is for a track duty m3 that sees 3-4 track days a year. They have never been rebuilt in the 11 years I have owned it. Any insight would be appreciated, thanks.

Hey all, Last October I picked up a used 2003 330i to convert into a track build and have been doing most of the standard preventative track maintenance this winter. One of these items is the shift pin/detent replacement since this car had intermittent 5th gear lean. 5th and reverse went by...

Hey y’all. I am new to this forum and here to find out some information. Let me tell you about my story. I was looking a e46 (330i or 330ci) and found this very mint 330i. I live in Clermont and it was in Miami, 4+ hour drive. My dad and I thought it was worth getting it even though I do not...

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...

Hello E46 Fantatics! I’ve been a lurker on this forum for well over a year now, and I wanted to take a few moments to express my deepest thanks to this community and all of the people that contribute to it. You’ve all been an amazing help to me in this journey into BMW appreciation. Big thank...

Hi guys, Recently took my propshaft out to replace the rather old flex disc and CSB. The rear CV joint on the propshaft was pretty stuck on the diff and after 3 hours of trying, it finally came loose, but had fallen apart. Ive tried every combination possible to put it back together but I seem...

Hi, long story short: I did a rebuild on my m54b30 engine. The reason was because more and more pressure was leaking throw the expansion tank, and when I did a block tester, it appeared my HG was blown but the engine never overheat, with me. When I opened the engine, I discovered that the...

I am rebuilding my calipers and the attached image is of one of the pistons. Overall it is in great shape except for the edge near the end of the dust boot. I expect that since it's near the outer edge it should be fine but looking for some confirmation from the forum. I really don't want to...

Thought I'd share my experiences trying to replace the cylinder head for under $1,000 in case anyone is thinking about doing this. This was the first time I'd ever even re-timed an engine, my background is mechanical engineering. If you're at all mechanically inclined and can follow...

Hello, I have done rebuild my M54B25 engine. I changed oil and filter twice. First after 150km and second change after 2000km. The oil looked like "metalic" for both oil changes, like oil on this Picture: Now engine run next 2000km (4000km after rebuild) Engine is non oil consuption, good...

So lets say you have the potential to acquire a free 2002 330i with M54/auto. The body is straight, engine is in desperate need of a rebuild, trans is still strong, interior(including some electronics) is shot. In this scenario what would you do? I am faced with this decision at the moment and...

Hello, I´m new here and I want to share my engine rebuild with you. My name is Honza. Cars and motorbikes are big passion for me from childhood. Cars of corse aren´t all of my life, I love adventures with scouts, nature, photographing, etc. I´m from Czech Republic. This is little facts about me...

Gentlemen.....I have read over many posts on here but this is my first. My son has the zf 5hp-19 in his 323ci 2000. It has very little reverse. It does back up but with any gas the rpm s go up. I can't get under the little Beamer and do not have the smarts to take it out. I believe it is the D...

Have had my 323i for about a year now and I cane across something just to good to pass up, an m52tub28 with 90k miles for 150$, it's sitting in my garage, first of all I'm doing a rebuild from the bottom up, asking where anyone has got a gasket and bearing set on the cheap, also has anyone done...

Hey guys, I just got my first bmw about a month ago and unfortunately I crashed it. Now I'm in the process of repairing it, but my local pull a part junkyard only has a 2002 e46. And I'm also a college student, so I'm trying to spend as little money as possible meanwhile still using good parts...

Hey I've been looking on the forums for a decent time but can't find anything on this! Is there a part # number list for a transfer case rebuild around? Apparently according to my friend (who is a mechanic at bmw) and his boss said they used to make rebuild kits for these, but discontinued...

I picked up a 2001 330Ci with a seized up engine, I really liked it because the body was very strait and in very good condition. I had meet the guy the day before and test drove it but it was making a weird noise so i meet him the following day at a BMW specialist. While the car was being...

I was thinking about doing a complete rebuild of my 325's engine. Based off of what I've researched I have the M54 model engine. Being all about power I was wanting to bore and stroke the engine just a wee bit to see if I can get a tad more juice. However there are no purpose built kits for...
