But there is a little part of me that thinks that >is somewhat wasteful, especially if some might be functioning properly. The pre-cat O2 sensors are the regulation sensors that the ECU uses to adjust fuel mixture. The post-cat sensors are used by the OBD-II section of the ECO simply to monitor the efficiency of the cats. I replaced only the pre-cat sensors based on Ramon LF's recommendation and that solved the similar CE and drivability issues my '96 was suffering a few months ago with no reoccurances. The cyclone filter can be cleaned out. All it does is capture the oil vapor and send it back to the oil pan via the lower end of the dipstick tube (that's a technical term...) Check the o-ring that seals the dipstick tube to the pan as a potential source of leaks. David 96 M3 - 179k miles, original cyclone filter

#5. Radiator Replacement - Thunderhill + August = muy caliente - from Jeff Conner

Date: Fri, 23 Jun 2006 23:05:54 -0700 (PDT) From: Jeff Conner <jeff.conner@yahoo.com> Subject: Radiator Replacement - Thunderhill + August = muy caliente Hey all, One of the items the mech who did my PPI for the 98 sedan I bought was the radiator replacement. He said it should happen "closer to 60k miles than 80k" due to a number of factors. I recently turned over 45k on the odometer, and I'm staring to wonder if I should just nip the problem in the bud, rather than wait til I have no choice. Like at Thunderhill in August. What I'm trying to figure out is if I should just go with another stock radiator, or should I pony up the 3x (or more) for all aluminum. There has been some discussion of turning the car into a gutted, track only toy, but that's down the road. Is there any significant advantage to spending the extra money?

(for aluminum radiator) Yes. You will have much greater cooling capacity. Neil Maller was an early adopter of an aftermarket aluminum radiator. He reported a very significant drop in oil temperature. In fact, he might have gotten a greater drop in oil temperature from the aluminum radiator than his oil cooler. If you are thinking of making your M3 a track car, I'd recommend the aluminum radiator before adding an oil cooler. By all accounts, adding an oil cooler to our U.S. M3's is a PITA. See if you even need an oil cooler after the radiator. Second significant advantage is longer life over another plastic neck OEM radiator. If you shop around, you can find an OEM radiator for approximately $150. So you can probably buy 4 OEM radiators for the price of one aluminum radiator. Maybe this isn't such an advantage if you don't mind changing radiators every few years. But you will have piece of mind. You won't be wondering "is this the day my radiator neck breaks - how much longer can I go?" Knowing Murphy, your OEM radiator will fail at the worst possible time causing the most damage and inconvenience. :-) Lowell Seaton '95 M3

I replaced my first two radiators as preventative measures. First one was done at 70K miles and the second was done at 140K miles. I went with the S54-M Coupe as my second replacement, and the neck went out at Sears Point with only 20K, and I was forced to go with an OE unit because of timing and location. My biggest reason for the swap will be peace of mind, but for the last two track weekends in 100+ degree temps, I've been able to watch the temp gauge creep up to the 3/4 mark, when it never used to move beyond half... Ever. Okay, maybe once, but that's why I'm on motor #2 now. :( Not sure if it's because of the cams and new gears, so my RPMs are often higher than they used to be, but I'm definitely not comfortable with watching the factory gauge move, so an aluminum radiator and that new Stewart water pump are in my not-too-distant future, as well as some "real" gauges so I know some numbers and not just a vague range of movement on the factory unit.
