Welcome to my BM-trouble-U pages.... (go on, say it out loud, you know you want to!)  Here's more on the car here...

This issue has been resolved!  All cylinders were blown (head gasket wise) the head was not warped.   At the time of removal coolant had finally breached into oil passages.   We pulled the head; used 3m pads to clean it & the block & had it back on the same day.  We used a cooler thermostat "just in case" and all seems to be well.

 

If anyone has anything to add or comments to make; I would be most appreciative if you could email me at jassing@centurytel.net and let me know.  This info is from several sources over 3 days of hunting & talking to people.

The Car: 1992 BMW 735i M30 engine E32 chassis 160K on the odometer

What's wrong:

  • I loose coolant, and occasionally get hot (needle climbs to the red, but comes back down on it's own.
  • Sometimes the coolant alert comes on; but needle stays rock solid in the middle.
  • I'm low on money.  The suggestions I'm now getting are putting this car into the 10K range, and I simply can't justify the money.

Suspecting:

  • Head gasket leak allowing pressure to escape from cylinders into cooling system, which pushes water out the overflow's "overflow tube".  When cooling, allows just enough coolant into the cylinder to water-foul a plug causing a momentary 'misfire' on startup.
  • We believe this to be something like this.

What we're doing.  This is a list of everything we're doing based on feedback (you can read everything here) and consultation with DanTheMan because I trust him.

  • Pulling the head off, having it surfaced; putting a new gasket on.
  • Replacing the tensioner.
  • Drilling out the overflow feed hole.

Because this page got so long; I broke it up...

Thanks for taking time to read this.

Thanks to Dan P. for the Cam Tensioner & Cam Removal lessons.
