I have been blessed by the Maintenance Gods today. During reassembly of the OFH, the top-right bolt hole (fig. 1 - circled in yellow) stripped out. I understand this is common issue with these engines so I want to offer the solution I've come up with, and ask for tips or advice before I fix it...

Hello! I am having an awful time trying to get my 2000 BMW 323ci manual in which I have swapped in a m54b25 running. I have taken the dme from the 325 which the engine came from and have had it reprogrammed with an ews bypass. The drive by wire accelerator pedal I have also wired up to the DME...

So I have a question to a problem I had with my old 323i I used to have, I never figured out or got an answer to what was wrong with it, and it still interests me to this day, and now that I have found this forum, I figured I should ask here to see if I can finally get an answer to my question...

Hey folks, I'm after some general info on my 99/2000 bmw e46 328i. I'm about to change the vanos so I was confirming my engine model using my vin. Now, my vin says I have an M53. I know of the M54 and the M52 but not the M53. I googled around a bit but there's no record of this I could find...

Hello, so I bought a wrecked 330ci m54 and I'm rebuilding it. I put it all together and after some time of driving it, I noticed a rattling noise after 2k rpms. It does it both in neutral and drive. It definitely isnt the lifters. It's coming from the rear of the engine itself (towards the...

Ight so im going to jump straight into it. Ive just purchased my new pride and joy, a very clean 325ci with only 140,000KM on the clock. Car cost me just under $2k but has a blown head gasket. I'm on a strict budget for this car. The old lady i bought it off only babied it and never went hard...

Hello! I have an E46 with an engine swap and just picked up an E36. I now have a 1996 ti with a 328 engine from a '96 vert. My brother owns a shop and did the work. Neither of us can figure out where to install the secondary air pump since there's not much space after the swap. We did a...

About three weeks ago my car started making a whistling sound. It sounded like a jet engine. At first it was RPM dependent. Only did it when around 1800-3000 rpms. Over the course of the next week it became almost constant. I heard it at start up. Just about all the time when I drove. Yesterday...

Hey all, I am looking into getting some TE37s for my 328i, and I I've narrowed my choices down to two different styles. Right now I have factory 17 inch wheels on my car of which I have no idea the specs on. The new wheels I'm looking at are 18 inches by 8.5. However, one set has an offset of...

Hi guys! I've had my 2000 E46 328ci for just over 2 years now with around 115,000 miles on it. For the majority of my ownership, it's had the roughest idle, along with a big loss in bottom end torque. Along with that comes the crap MPG and intermittent P0170/P0173 code, which only happens on...

Hey all. I have a dd 330i that I'm very pleased with and I'd like to look at getting a second e46 as a project. Here's my idea. I want to turbo a bmw very badly. Maybe an e30. Maybe an e46. I've researched to death about boosting the m20, lots of people do that. Lots of people also...

Experiencing cold idle dips/stalls and minor shifting hiccups that have been present pretty much every since I bought my car a year or so ago. Quite a bit of work has been put into the car ever since I took it over. It is pretty darn clean and has 114k miles now. Brief overview of repairs done...

I have a 2000 BMW 323i with the M52TUB25 engine that puts out a tired 170 hp and 181 ft/lbs tq and the autotragic ZC transmission. I was wondering what OE engine upgrades I can switch from different bimmer engines M52-M54 Or even the S engines. Also any different year manual transmission work in...

After I got my front tires replaced today, I came back home and saw my neighbor working on his 2004 BMW 325i. I went to ask if he needs help. To my surprise, I saw a really weird engine in the engine bay. He has 2004 e46 325i with N46 engine on it or something similar but everything else in the...

I read an article today in "Total BMW" magazine about an AC schnitzer E46 that they called the AS3 (only offered in europe of course), which has a 375hp NA M52TU 3.2 litre. Im really more interested in the engine. All it said in the article was bespoke, performance pistons, and forged conrods...

What I need: -clean motor (one of us is going to test compression before the purchase) -all accessories working - that means alternator, PS pump, alternator -includes engine harness -includes intake mani, throttle body, intake stuff -prefer to have e34 oil pan already(ie pulled from a 525)...
