When at speed the I-6 is as smooth as mine. I'm thinking motor mounts but they looked fine when the clutch was done. The mounts are probably the originals (90k miles ago). He's also running the UUC tranny mounts. Any other ideas to look at to solve this problem? Water pump and V-belts are all new. How does the nut backing off the oil pump manifest itself?

I thought the oil pump nut backing off thing was only on M3 e36 models? ??? So ANY M50 or M52 or S52 motor it will happen on???? Now you have me worried!!! Thanks David Jalali ------------------------------ Date: Wed, 20 Sep 2006 08:38:02 -0400 From: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> To: [email protected] Subject: Re: <E36> Curious vibration Message-ID: <[EMAIL PROTECTED]> Actually, what it likely is (if related to the UUC tranny mounts) is over-torquing them. We provide explicit torque specs in the install sheet, 16lb-ft... which are often completely ignored. If over-torqued, vibration will result. 16lb-ft is just a little more than finger-tight. Try loosening the mounting nuts. Secondarily, we see pre-loading of the transmission or transmission support brace as a contributing vibration factor. When installing, the brace itself should be secured to the floorpan of the car with all retaining nuts on the bushings loose. Set the transmission on top of the bushings and remove the support jack completely. This lets the transmission sit in an unstressed rest position. Only then should you tighten the nuts on the tops and bottoms of the bushings... 16lb-ft being the magic number. - Rob ----- Original Message ----- From: KMS- Brett Anderson <[EMAIL PROTECTED]> To: [EMAIL PROTECTED], uuc Digest <[email protected]> Subject: Re: [UUC] <E36> Curious vibration Date: Wed, 20 Sep 2006 01:24:50 -0400 > Without experiencing it, I'd say just remove the UUC trans > mounts and put stock mounts back in. > > If the vibration is still there, then look elsewhere. > > > Brett Anderson > KMS-Koala Motorsport > www.bmwdiffs.com > (440) 564 7574 > 9988 Kinsman Rd > Novelty, OH 44072 > (Near Cleveland) > > > [EMAIL PROTECTED] wrote: > > On my son's '96, 328 when at idle if you stab the > > throttle there is a vibration felt in the seat whereas > > on my '99, M3 it's smooth once warmed up.

You thought wrong :-) First instance I heard of this happening was actually on an E46 330, IIRC. > So ANY M50 or M52 or S52 motor it will happen on???? Yep, they're all the same, oil-pump-design-wise.

I don't suppose this was at the Sears Point HPDE back in March this year. I know the car and owner. It needed a replacement motor, unfortunately.

Right now she's dirt poor and just lost her job yesterday. I noticed that the the coolant was above the "cold" mark when warm, but that when I slowly cracked the pressure cap and let the pressure bleed off, the level of the coolant in the translucent side tank of the radiator ROSE. The logical thought is that there is air somewhere in the cooling system, and that when I released the bubble of air at the top of the radiator, the trapped bubble of air elsewhere in the system expanded and caused the rise in the radiator level ? So - without a Bentley - can anyone either tell me or point me to a link that tells me how/where to bleed the system?

It has a large + in it to accept a large Philips screwdriver. Gary Derian > Please, Can someone explain (because it's my daughter's new to her) how > to bleed an E34 525i cooling system.

Coolant expands with temp, hence having a "cold" level mark. Is the car overheating? Is the heater not working? If no to both, put the cap back on, close the hood, and leave the car alone. At most, check it when it's cold, and see where the level is.
