  1. Oil leak through exhaust manifold?

    E60 M5 and E61 M5 Touring Discussion
    After removing the front subframe for my rod bearing job, I noticed pretty distinct signs of oil weeping from the studs of the exhaust port of cylinder # 1 on the passenger side of the vehicle. A lot of the oil in the surrounding area is from a previous leak through the oil cooler that didn't...
  2. Sudden Extreme Oil Loss - 1 Liter/250 miles

    E60 M5 and E61 M5 Touring Discussion
    So, this is becoming increasingly worrying, especially as just now it lost about half a quart or so in ~55 miles. My usual consumption has been low enough that I haven't had to think of it much, I'd say around 1/1000 or 1/1500, which is perfectly fine and certainly what I would expect of this...

    E39 M5 and E52 Z8 Discussion
    After chasing down multiple water leaks in my 2002 M5 (thanks for all the posts about door vapor barriers, sunroof drains, seals around the cabin air filters and associated drains, etc) I'm down to these last two, which are small rust holes in the firewall just behind the drivers side gas and...

  6. Place to rebuild steering box rebuild (or source a new unit??)

    E34 M5 Discussion
    Does anyone know a reputable place to rebuild my steering box? I have a pretty significant leak from mine. I put an order though a month ago through a dealer, but the part went from backordered to NLA. I also attempted to source one from BMW Classic, but they don't seem to offer it any longer...
  7. DIY: Radiator Replacement

    E39 M5 and E52 Z8 Discussion
    Since the only DIY on your radiator is for a 530, I'm going to do a writeup for my M5. I'm in the process of pulling the radiator now. I made a few mistakes along the way (and will eventually post pictures.) Tools needed: 1-1/4" wrench (or metric equivalent) for pulling the fan. Dual-hole fan...
  8. MY2000 Vanos Leak

    E39 M5 and E52 Z8 Discussion
    My M5 '00 (55000 miles) had a big Vanos leak (bank 1, passenger side) about a year ago. It started during the spring, right after it got warm. First, the exhaust note changed, especially if you lift off in 2nd/3rd and coast in gear. It used to sound crisp and defined, and it changed to as if...

  10. Oil/fluid leakage from gearbox!

    E60 M5 and E61 M5 Touring Discussion
    Hey guys! When lifting up my M5 the other day, I noticed some leakage. Drops hanging from the motor/gearbox protective covering. Not much, not even a drop on my garage floor, but I put it on a lift and removed the covering. The leakage came from what looks like an oil plug at the right side rear...
