I understand that the exhaust valve seals are most likely the culprit? Has anyone else had this problem? Should I buy a complete head, rebuild mine to stock, or performance rebuild? What is the going price for rebuilding the head? It is about 1 quart every 1k. Money is tight, but I would like to get this fixed soon.

Here's what went through my head when I read Sean's post: "So, I was rigidly fixed (infinite-point harness) in my giant steel ball the other day, and I was driving along, minding my own business. I had no way of knowing which way I was going, or how fast -- save for the juice swirling around in my ears. Then suddenly, out of nowhere, I hit this other giant steel ball! Or he hit me. We think. Neither of us is really sure, because there were no witnesses, and without friction, it took a really long time to get stopped and get out of our balls to check out the non-damage that resulted from the perfectly elastic collision. Sheesh. Wait 'til I try to explain this to the adjuster..." - - -N.

After a quick look under the hood it seems to be coming from the aux air just on the other side of the firewall. All ventilation was off. The noise started today and (only) did it twice when the car was cold. It also went away after a restart after the car warmed up a little. Could this have anything to do with my recent M3 factory muffler swap? I'm planning a road trip to Portland OR from Seattle this weekend and hope to take this car. Should I worry about this issue or will it only have mixture problems at startup? Any comments appreciated... I am thinking of going to aftermarket shocks and was thinking about the adjustable Konis. I don't think I want to lower my car much more than it is now with the sport suspension. Are the Konis that easy to adjust without tools or jacking up the car? Are there notches in the adjustment wheel or is it free turning for finer tuning? Any pros and/or cons dealing with these shocks (or others) would be appreciated. I plan on replacing the rear shock mounts with E46 ones while this is done. Any other items I should add to the work list if I go this route? The car has 67K on the clock. Also, do the front Konis's use the factory shock mounts so I can continue to use my strut bar that currently uses the factory mount bolt pattern? What Koni resellers would you recommend?

I plan on keeping the car so now I'm researching my various repair options. It's an '89 with 5 spd. Boring options: 1. Rebuild bottom end 'in place.' I'm waiting on an estimate from my shop for this option. With all the extra iX bits up front that would have to be removed to pull the oil pan, I'm guessing that this option will be too labor intensive to be cost effective. 2. Just yank the motor and have it rebuilt or stuff in another decent used motor. This may be the best way to go. Fun options: Here is where I need some suggestions/ideas. This car gets a lot of use and I'd like to keep down time to a minimum of a week or two. I'd also like to keep within a $3K to $3.5K range so let's not go crazy here. If it is a fairly straight forward motor swap, I'm capable of doing that myself pretty easily. I'd try my hand with the motor rebuild if I didn't need it done quickly but for this project I'd be farming out any motor work beyond simple T-belt and seal replacement type stuff. 1. Rebuild motor with some extras? 2. Stuff in an E36 325 motor? Not sure what all is involved in the swap but the oil pan could be the deal breaker. Will the E30 oil pan fit directly or perhaps can the E36 pan be easily modified to accept the front drive shaft? 3. Other motor options?

You've obviously never tried to adjust Koni SA rears. Whereas the fronts have a simple adjustment stem at the top, the rear adjuster is an internal dog clutch. Here's the exact procedure: 1) With the shock off the car, disassemble the RSM and remove the bump stop. 2) Brace the shock's eye against the floor and fully compress. 3) Go to Emergency Room to have 10mm hole in your hand from pointed end of shock shaft repaired. 4) Once you get back, wipe blood off shock and reassemble RSM to use as handle. 5) Repeat step 2, this time avoiding severe bodily injury. 6) While maintaining about a zillion pounds of pressure to keep the shock compressed against its internal gas pressure, rotate the shock's shaft with respect to the body using a delicate touch, until you feel the internal dog engage. (Previous experience as an OB-GYN helpful.) 7) Keep the shock compressed, and rotate the shaft in your choice of direction until the end stop is reached. Don't force. 8) Back off the shaft to the desired angular setting. No, there are no clicks. Why yes, you do still need to hold compression. Feeling the strain yet? (Previous experience as a Sumo wrestler helpful.) 9) Release shock. Disassemble the RSM. 10) Reassemble the bump stop, washers and RSM, preferably with everything in the correct order and orientation. 11) Reinstall shock on car. 12) Repeat other side, optionally omitting step 3. There, a simple 12 step program, isn't it? Or: Traditional option: take a deep breath, open wallet wide, and buy Koni DA rears. Adjustment is now external for both bump and rebound. Price is about $625. Each. Don't say I didn't warn you. Alternative option: TC Kline now offers factory-made externally adjustable Koni SA rears for $180 each, which is only $45 more than the normal version. Why that's less than your medical bill for step 3 above! TC's guy says these are exclusive to their shop. That I can't confirm, but I do know that $380 got a pair of them to my door last month via UPS. Note that both these externally adjustable Konis have 12mm threads instead of 10mm going through the RSM. This means you need to bore out the RSM and its washers to suit. This is easy with Ground Control RSMs, which have no central sleeve, but may be trickier with others. You'll also need to provide access inside the trunk to the adjustment stem. > Any other items I should add to the work list if I go this route? The car has > 67K on the clock.

Yes they do. > What Koni resellers would you recommend? TC Kline if you go with the second option above.

This is an Alusil block, with crank/rods/pistons installed from the factory. It comes with almost every gasket in the engine, and even spark plugs. If you have a 530i with a Nikasil block, it might be worth buying this and putting it on the shelf. Retail from the dealer is close to $6000 for all this stuff, selling for $2500.

There was an M50 525iX, so there is an appropriate oil pan for the motor, and for doing an M50 into E30 swap, you use the 525i oil pan, so it should fit the hole..... But....... Lotsa money, lots of work, and no way to tell if it will work without actually doing it. - ----------------------------------------------------- BMW Special Tool Rentals Pay per incident tech support - ----------------------------------------------------- Brett Anderson KMS (440) 338 1650 www.koalamotorsport.com OSS committee member > -----Original Message----- > [mailto:[EMAIL PROTECTED] Behalf Of Pharr, Jeff > 2.

If the motion of the balls is also known, then there is only one solution. To take this further off topic ... When I first got my hands on kinematics software I set out to model a "perfect" multi-ball knicker-knocker toy thingy. ||||\ OOOO O In the computer I could model the strings as perfectly rigid, the connection points as frictionless, no air resistance, etc. In order to make it work, the suspension points for the balls must be slightly more than the ball diameter. If all the balls are touching, the energy transfers from the moving ball to the other four in together, rather than one-to-one-to-one ... Etc. In any case, even a "perfect" model will only swing for a limited time before all the balls start swaying to and fro. The small gap between the balls means that each "static" ball is actually pendulating (is that a word?) after its collision. This accumulated pendulation increases over time, thus the balls are not in ideal locations on subsequent collisions. It doesn't take long for this error to accumulate and screw up the action. - -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gary Derian Sent: Thursday, April 03, 2003 9:05 AM To: [EMAIL PROTECTED] Subject: Re: [uuc] <OT> Collisions 3 balls in a single collision?
