#1. PCV valve replacement - from Juan Bruce
Top
Date: Wed, 09 Apr 2003 22:36:11 -0700 From: "Juan Bruce" <jbrucebmw@hotmail.com> Subject: PCV valve replacement Recently my motor started burning quite a bit of oil despite having good compression and leakdown numbers. A friend (hi Andy) suggested that the crankcase ventilation valve might have gone bad. Sure enough when I pulled off the intake boot before the throttle body there was a lot of oily residue. So my question now is how do you replace the PCV valve? I could not find instructions in the Bentley manual. Also, is there anything else I should replace while I'm at it or any other parts I should have on hand? If the throttle body and intake are full of oily residue is it worth taking them apart and cleaning them? How about the plugs, should I replace them too? Thanks, Juan Bruce BMW CCA GGC '85 M635CSi '95 M3 _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus

#2. RE: [E36M3] Drivetrain losses - from Patrick Buthmann

Date: Thu, 10 Apr 2003 07:16:12 -0400 From: "Patrick Buthmann" <patrick@teutonic.ca> Subject: RE: [E36M3] Drivetrain losses Lowell, Yeah, it's typically a point of much heated debate (which Jim and I have gotten into several times before, among others). Really, the only places driveline losses should occur are places in which the drive angle is changing (ie, the diff). Tire slippage is minor, if any, and if the tires were actually slipping regularly, you'd see that in lost power over the course of the entire dyno plot. You may get some driveline losses through the transmission (since you're using multiple gearsets, with some backlash allowed), but this is generally sub 1%. Same thing applies to driveshafts, CV joints, axles etc....losses are minimal (if any) through them all. Another problem with dyno tests is that operators typically test a car in 3rd gear (1.67:1), rather than a more accurate 5th gear (1:1). By testing in 5th gear, you eliminate any change in the moment arm (part of the torque calculation) and you get a more accurate dyno plot. There are a number of independent shops using some of the newer hub/bearing based dynos (as opposed to roller dynos) as engine dynos, with just a blank frame (no transmission), and a 1:1 rear diff to hook up to. Works pretty well, and they have been using 8-10% as their driveline loss numbers as well. These units also eliminate any concern about tire slippage (which I've yet to see) and the more noticeable problem of a 3500 lb roller not being calibrated for cars other than 3500 lbs... Remember, Jim makes his money from showing bigger HP gains (per his chips and Shark Injector), so take some of that information with a grain of salt. HP sells, and I can't fault Jim for his position, regardless of it's accuracy. 17.3% driveline losses on a 240 HP car would result in sub 200 rear wheel HP in an E36 M3, and I don't believe anyone here is seeing a number like that. No E36 M3 (stock) that I've seen or tested has come in at anything below 215 rwhp (give or take a HP here or there), and 215-220 rwhp is the typical range. 17.3% sounds nice for the owner when their car dyno's at 220+ rwhp stock, but do you think BMW really left 30 flywheel HP off their sales brochures? For an interesting read on some dyno inaccuracies... http://www.sdsefi.com/techdyno.htm Pat > Actually, it's more like 245-250 HP at the crank. A lot of people > wildly > overstate driveline losses, but at best, the rear diff on a BMW is worth > 8-10% driveline losses. The tranny losses are minimal (sub 1%). Bosch > automotive manuals support these statistics as well (and Bosch is probably > one of the largest builders of engine and rolling dyno's in the world). Interesting. I remember Jim Conforti stating on this e-mail list that the drivetrain losses for almost all manual transmission BMW's is 17.3%. That means you divide the measured rear wheel horsepower/torque by 0.827 to get flywheel values. Patrick - do you need to count the tire friction loss in your figure too? Maybe if you add up tire, CV joints, differential, drive shaft, and transmission losses you would get the commonly used 17% figure?

#3. 40 wt Oil - from Brad Ahrens

Date: Thu, 10 Apr 2003 06:14:25 -0700 (PDT) From: Brad Ahrens <txsaggie97@yahoo.com> Subject: 40 wt Oil For what its worth if you are interested in a 40 weight oil Walmart (at least here in Dallas - Lewisville location to be exact) has a rollback on the Shell Rotella T 5w-40 full synthetic gallon jugs of oil. Down from 18.88 (more than Mobil 1!) to 12.88. Quite nice at that price. (Sometimes have the Mobil 1 cheap as well but I haven't seen it in anyting but 10w-30 and 5w-30) My roomate who is quite inquisative and has WAY too much time on his hands did some research on this stuff. Supposedly it is well regarded on message boards devoted solely to Oil out there (and you thought WE were crazy about our oil discussions). It is not base 4 like Mobile 1 but one of the best base 3s out there and the same base that Shell uses for their ultra helix or the like that is factory syn fill in many euro cars. Just what he told me..and as I remember it. Jist of it was it compares in testing very well to Mobil 1. I will be giving it a shot. __________________________________________________ Do you Yahoo!?

#6. Engine Shimmy : Reposting - from Steve Klein
Top
Date: Thu, 10 Apr 2003 09:16:45 -0700 From: Steve Klein <klein@robinsonad.com> Subject: Engine Shimmy : Reposting the list seems to have eaten this twice. . . Hello, Group- I'm hoping some of you can help to shed some light on a situation for me: Last night, I installed the UUC tranny mounts with the enforcers and I think they've highlighted a problem that's been lurking for a bit. With the car parked and in neutral, revving the engine reveals a vibration that is most pronounced between 1-2k rpm. I had felt a similar vibration to a MUCH lesser degree, but only around 1.7k rpm when I had the old mounts installed. I DO NOT think it's the new mounts causing the problem (I had to loosen the brace bolts and re-tighten once, but the shifting is a dream and as I said, the vibe happens in neutral with the car stationary as well as moving) but rather presenting it much more directly since they're so solid. I had the right side diff seal replaced again on Monday and pointed out some fluid coming out of the seal just fore of the output flange and guibo on the tranny, and that the release bearing is starting to make some noise. To that end, this morning I ordered a Sachs clutch replacement kit (clutch, p.plate, r.bearing) and the 11lb. Lt.Wt. flywheel from UUC, planning to head back to the shop early next week to dig in and replace such. I'll probably have a guibo (heretofore referred to as a Guido, as in The Killer Pimp) and center bearing for the driveshaft at the same time. The seal on the transmission is bugging me, and I'd love to hear any other thoughts on A) what might be going out and causing the vibration and B) what else I should have done in that area while the car is apart. Thanks again for all your help Steve

I'm still skeptical about an opinion from a guy who sells oil, versus an opinion from a Mechanical Engineer who deals with this particular subject. As someone else said, everyone has their own opinion, and some people can state theirs in a very convincing manner. So, without the educated statement from a knowledgeable M.E., I'm still skeptical when someone tells me that 0W-30 synthetic oil (recommended by a guy who sells oil) protects and performs as well as or better than a 15W-40 petro oil recommended by the manufacturer.
