Date: Thu, 15 May 2003 15:16:04 -0400 From: "Luis Rueda" <Luis_Rueda@Interliant.com> Subject: Re: Power steering fluid Thanks to David and Jim for answering my question, wish me luck! : ) Luis When I've had the fluid replaced on both cars, my mechanic has used Red Line High-Temp ATF. Track use, especially as Sears Point, could cause it to overheat and vent out of the reservoir. I would think any good quality ATF would be fine for "normal" use. I think I requires less than 1 quart. Hope that helps, Jim Bassett 1998 M3/4 1993 325is #44 JP/A5

#2. Teach me about compression - from Jon Phillips

Date: Thu, 15 May 2003 12:36:29 -0700 From: jon@maximumpc.com (Jon Phillips) Subject: Teach me about compression These questions have always nagged me, so I thought I'd shoot them to the list. When I bought my car three years ago, I was much less tech savvy. I knew consistent compression numbers accross all six cylinders was important, but I never took the time to learn what compression for the S52 should be (in new form out of the factory). - My numbers three years ago were 172 accross all six. These seem low given other compresison numbers I've seen reported. But I've also heard that compression results can be all over the map depending on testing conditions, and that consistency is most important. Did I get a good engine, or are the numbers too low under any circumstances? If you know what you're talking about, please feel to write me a friggin' white paper on compression readings. You won't bore me. - How exactly does compression relate to horsepower? In other words, let say that over time an engine drops from 190 psi to 170 psi accross all six (hypothtical example; just making this up). How would such a drop relate to ever-diminishing horsepower returns? Is it a one to one correlation? Are we talking 5hp? 10hp? Or another way of looking at it: How much slower is an E36 M3 with 250,000 miles versus one with 50,000 miles? Thanks, listers. Hopefully someone is ready to geek out on compression theory.

What drained out was brownish and smelled like used up ATF - which is what it was. It should have been done sooner. My method: 1. Get both front wheels in the air. 2. Remove lower banjo bolt (22mm) on PS pump (I reuse the crush washers once but don't tell anyone.) This will drain most of the reservoir and the pump. 3. Remove the "trombone pipe" banjo bolt from the top of the rack. Swing the tube around (remove retaining screws, of course) and drain as best you can. 4. Swing the front wheels full lock each way a few times *by hand* to purge as much as you can from the pump and rack. 5. Once it all seems dripped out, put it back together and add fluid to fill the reservoir (I use Redline PS Fluid). Start the car and run the wheel back and forth a few times to work out the air. Check the level etc. I've never added a quart so there is some fluid that isn't getting changed. The system is said to hold 1.5 quarts when bone dry.

So, unlike my normal method, I didn't do any research or investigation ahead of time to see how easy or difficult this would be. I quickly found out two things: - The euro oil filter housing is different in that there are two sender ports M12 x 1.5 (oil pressure and oil temperature) and no VANOS connection port while the US oil filter housing has one sender port M12 x 1.5 (oil pressure) and the VANOS connection port (M14 x 1.5 I believe). This appears to be easily remedied by simply tapping the euro filter housing for the VANOS connection. Correct me if I am wrong. - The ancillary pieces I purchased were as follows: 17 51 2 243 659 1 holder - plastic bracket with an unthreaded brass insert 17 22 2 227 282 1 euro holder - metal bracket with two holes one is threaded for M6 it looks more Euro than the plastic bracket 17 20 1 712 209 4 plastic snap together brackets with holes in them 17 22 2 227 340 1 bolt - an M6 x 30mm bolt 11 65 2 243 770 1 bolt - an M6 x 20mm bolt 17 22 1 712 349 1 spacer - flared unthreaded bushing To me, these pieces seem useless. I can't tell how they would be used to hold the oil cooler in place at all, at least not on the US car. I can see how I can fabricate my own metal brackets which would insert in the plastic brackets on the under side and hold the oil cooler in place. Has anyone else done this or are there brackets already fabricated out there?

The oil lubricates the transmission and not the flywheel/clutch assembly. Does the rattling come from the transmission itself due to the lower rotational mass of the system? Does it come from some resonance with the heatshield due to a different harmonic or vibration? I haven't experienced this but have just installed a LTW flywheel myself so I'm interested in the answer. I don't see how the two connect.

But, I also have a Turner ltw flywheel, and it's been pretty noisy, typical rattling sounds in neutral at idle. I was going to try the Redline Shockproof HEAVY oil, because of a lister's anecdote that this dramatically reduced his ltw flywheel noise without making it more difficult to shift, but a friend and mechanic talked me out of it saying it was just too heavy an oil. So, I tried the Royal Purple. The noise is reduced by about 75%! However, the downshift from 4th to 3rd is definitely stickier, with higher possibility of grinding the gear. Just another data point.

Push the clutch pedal in at idle/tranny in neutral, rattle should go away. Release clutch pedal, rattle. At least, that's how it is on the race car.

Correct. The warranty covers the parts *failing* - i.e. no longer functioning as emissions equipment. I wouldn't have expected heat-shield rattling to necessarily be covered (but some dealers might <shrug>)>. YMMV, of course.

I seem to remember a whole bunch of people reporting recently that they had done just that - the dealer had replaced the cats under emissions warranty because the heat shields were rattling. -- Greg Cagle gregc at gregcagle dot com
