Message-ID: <[EMAIL PROTECTED]> I have zero exposure to an E34 but that sounds very similar to the symptoms of a rear subframe mounting point tearing loose in an E36. I hope for your sake an E34 and an E36 have nothing in common when it comes to a rear subframe.

Thanks to all those who made suggestions. I'll start checking those items: Center bearing is only 1.5 years old, but I could have a bad one. The rear bushings have 100k miles on them so that is a real possibliity. Fortunately, nobody has suggested anything that is going to fail catastrophically.

I have torqued the crank bolt using a two foot breaker bar with a four foot extension section of pipe, two adults sitting on the front fenders, and a 18 inch plumbers wrench/monkey wrench holding the crank hub still while trying to lift the car off the ground as its steadying the hub. I thought the main relay would keep the car from starting by not supplying voltage to the DME, no? I'm trying to get a friend of a friend to let me try his DME from his car to rule that one out. Engine smells of fuel quickly after trying to start it with no luck. One thing I've noticed is that the engine will appear to start the very first try within a frequency of a couple of hours rest, and the starting sensation lasts for half a second ot a full second and then stops, as if something has interupted the starting cycle...at a loss here.

The plug that was held out, grounded to the valve cover, to check for spark was firing a solid white spark repeatedly, no interuption. The ignition system has, new plugs, new wires, new coil, engine speed sensor, and new cap and rotor all within the past year, plugs were this weekend.

Peter, If you do this, be sure to try your DME in your friend's car, not the reverse. If your DME is toast it won't do any harm to install it in his car. On the other hand, if your car has a short or some other problem that damaged your DME you could blow his good DME by installing it in your car. Maybe not likely, but why take chances? One other possibility - I had a troublesome no-start problem on my E36 a while back that turned out to be the battery. When I couldn't start the car with a jump I assumed the battery wasn't the problem and went looking for all of the other possible causes like you have done. After testing sensors, relays, etc., swapping in a new battery solved the problem. I think the battery may have developed an internal short or something, and no matter what else I did, it wasn't going to start as long as it was in the circuit. Just a thought, and easy to try.

It can take some time to get it off but it will loosen. I used a combination of contact cleaner and DeOxit gold to condition the pins once I had it apart. -Kevin ---------------------------------------------------------------- This e-mail communication is confidential and is intended only for the individual(s) or entity named above and others who have been specifically authorized to receive it.

Wet plugs leak ignition voltage and prevent enough buildup to spark. Gary Derian > > Engine smells of fuel quickly after trying to start it with no luck.

It's bent and has its inside lip torn, probably from being wedged into the backside of the one remaining alligator-tooth berm on the whole course (they're smoothing out the berms for Moto GP). Is the wheel basically done? It's an aluminum alloy wheel --- the BMW M68 that comes on sport-packaged E46 cars. Do I have an excuse to buy some BBSs? --Andre ------------------------------ Date: Tue, 3 Jan 2006 11:48:54 -0500 From: "Beaudette, Roland SIKORSKY" <[EMAIL PROTECTED]> To: "UUC (E-mail)" <[email protected]> Subject: 90 525iA blower motor (IHCA) Message-ID: <[EMAIL PROTECTED]> Well, I appreciate everyone correcting me. I had reviewed the procedure months ago and thought the wipers were involved. I will eventually need to address the wipers as the passenger side has succumbed to the dreaded interference with the driver's side malady. So for warmer weather (nor'easter today) but while all of you are thinking about it for me, is it safe to pull hard? Heat? Impact wrench? I suppose if there is a die grinder available, I can just grind the offending material away.

I don't know if you *have* to, but it's never a bad idea to degree the cam and check piston to valve clearance when doing a cam swap, especially when increasing duration.

Message-ID: <[EMAIL PROTECTED]> Hi everyone, I just purchased a 10/96 manufacture E36 M3 Sedan. The Check control with temp display is all garbled and I'll need to replace it. I'm wondering if I can upgrade to OBC instead. I don't need the 'toggle' function offered by the button on the end of the turn signal stalk.
