    ....narp? t

    Not the heater, but it would make the windshield wiper linkage a lot easier to get out... t
  3. TobyB
    yup. neither of you are ready... t

    I thought about going to sealed bearings in back, but for raceycar, I was hesitant for thermal management reasons. For streetycar, good idea! t

    There have been changes, for sure. Beyond that, I don't know much more. Given that Schrick's been developing cams since these cars were new, it makes sense that they'd improve them as they went. And things they learn about one engine can, with care, often be applied to many different engines that share similar dimensions or quirks. I guess that's why they describe them by their duration at >1mm, rather than other, more specific values that, frankly, tell more about what the cam will do in an engine. t basically a gratuitous bump- having a local-ish cam grinder made it cost- ineffective to 'trust the doctor'

    So THAT'S why a few alternators have that! I always wondered, because it seemed period, but also not all that common, and not 'factory' but NOT aftermarket, either. That said, a condenser on an alternator output's not going to do a lot of noise suppression. It'd work a lot better on a generator's switching noise... t would suppress the slip rings, tho.

    Yeah, I've found those brackets on various year shifters, but seldom with a switch attached. I have a 'fond' memory of getting stranded in a Western Auto parking lot in Burley, Idaho in our then- new '74 Datsun 710 when the same thing happened. There was a red button under the hood that you could push to reset the interlock, but it took about a half- dozen tries with a 6- year old trying to crank the car before the damned thing started. We then drove it to the dealer (probably in Boise) and sat in the car, in the service bay, until they defeated the system. 'I can't do that, ma'am' 'Then I can't move the car' 'Ma'am, you can push the button' 'Not if I'm sitting in the seat, can I?' t

    Looks good to me! Being able to take that out for cleaning and maintenance makes good sense. Can you snug those nutsert fasteners good-and-tight? bkuz- That panel is an odd one- besides being a bracket to support the hood latch, it also has the ability to transfer lateral loading between the firewall and the windshield frame. Whether it actually DOES so is a different question- but given how little structure there is in the firewall, and how beefy the front 'inner fender' structure is, it's quite possible. It would be absolutely amazing to be able to see the original design studies when this body shell was designed, because it's obvious a whole bunch of thinking went into the load path calculations. But in 196-low, in a smaller, older, struggling company, the calculators would have been slide rules... t

    Since that nut didn't exist on the car during (or even for decades after) its manufacture, there won't be an original torque for it. I don't remember when it eventually showed up- E36 era, maybe? One of the dumber- of many- BMW cost- saving measures. If I was a person who regularly used a torque wrench, I'd find the earliest stated BMW torque and use that. 35 ft- lbs seems to be in the right ballpark. t still uses blue loctite, but also uses sleeve retainer.

    While wind tunnel can be the most effective, real- time data logging (from a gopro looking at strings to pressure sensors linked to an inexpensive logger) can be equally as informative, and a small part of the day-of work for a track day. I did a low- effort real- time tire temp monitor, and we learned a LOT, later, from having the data. It looks to me like the biggest bang for the buck is just a tall rear 'spoiler', a la Nascar. That said, I run a very lightweight rear shell of a decklid, and if the rear trunk surface was generating much lift, it'd distort that lid a LOT. I guess I should video the thing to see for sure, but I've never seen it lifted noticeably in other people's video of my butt... t not photogenic
  11. TobyB
    Thanks for that! Especially the explanation of the lift with reduced underbody flow. -or from rules restriction. With race cars competing in restricted classes, many aero 'common sense' mods (like closing your windows) are specifically prohibited... even in relatively free classes like GT. t
  12. TobyB
    Yup, it was a mid- 71 change. I thought it came with 12 fuses and the rest of those changes, but as with everything BMW from that era, 'your mileage may vary' t

    The front fenders do add some structure to otherwise floppy nose pieces, but as to how much deflection they reduce in normal use... probably not a lot. They ARE quite rigid, so they help some. The doors- only in a crash, when the pillars move relative to each other. For a cross- town tow? Not enough to matter, for either, for sure. These cars flex a lot- it's intentional. Or rather, it's an accepted trade- off of how they're built. I'm sure the chassis designers would have preferred them NOT to, but the production engineers- the ones who had to live in the real world of weight, cost and manufacturing realities- told them to suck it up, buttercups, and get back to work designing that 5 series. t

    If you're handy, there are lots of ways to cut the hubs down a bit. The first time I did it, I think I roughed it with an angle grinder, then made a sleeve to mount the things in a drill press, and used the angle grinder to round it off nicely. When I was finished, it looked like it had been done by someone who knew what they were doing! t
  15. TobyB
    holy cats- yeah, thanks, that's not much more than a pair of regular old round headlights. I ordered a set for the FJ60. heh t
  16. TobyB
    Lube, plastic pry tools, and heat. And don't be afraid to REALLY fold them. t

    I want a sheet of that stuff that's the size of my rear window. To flip it up when a Tesla gets up my chuff. Oh, and pull the choke out to full rich, too, just for spite. t
  18. TobyB
    There is an oval non- crush sleeve in there that prevents that- I had thought the same thing when my shaft came up... too long. Alas, no, she said. t

    Merrrffff... you know, I've never seen a rubber coupling spreadsheet, with all the different sizes. God knows, there are at least a hundred different ones, over the decades and manufacturers. The auto coupling is too large in diameter- the bolt circle is bigger. But there's a small E30 version. I don't know how thick that is. I'll bet RealOEM doesn't give dimensions, but that'd be the first place I'd look and then start trolling through different models and drivetrain options... When stuck with the opposite problem, I have milled 5mm off a 4- bolt without any ill effects. And I'm just nuts enough to try using hardened washers to spacer the coupling back a little- E30 head bolt washers are 10mm. I would NOT do it with a non- hardened washer. t willing to try all sorts of questionable ideas.
  20. TobyB
    yes- sort that temp sender. The M42's DME is easily confused. Me, I'd measure the voltage on the DME sense pin. And +1 for stable voltage at the battery, too. t http://www.wedophones.com/Manuals/BMW/1992 BMW 318ic Electrical Troubleshooting Manual.pdf

    the lack of o- ring's a big ol' air leak right there.... and that paint job reminds me of something... hmmm... Oh, yeah, that summer in college I spent sealing cracks in asphalt... t
  22. TobyB
    if you wanted to go super- stealth, there's a Volvo 142 distributor that uses a second set of contacts in the base of the distributor to trigger the D-Jet setup they tried for a few years. VW used the same thing in the later T3's. t
  23. TobyB
    Yes! That's perfect! t these cars weren't meant to last 5 years....

    Do you mean that it's 194 f while it's running? Because if it's reading 194c at any point, you're not getting a good engine temperature signal, and that will certainly cause trouble with idle. It's not a bad idea to meter the sender- you're looking at the voltage- and see if it's stable as the car starts and warms up. Grounding can mess with this, too, so if you're dedicated, meter the sender end AND the pins where they enter the DME. It's harder with the earlier DMEs- they just aren't as chatty as the OBD2 versions, and the data they provide is often not interpreted correctly by more recent readers. This was a tough time for engine diagnostics- mechanics are hard to train, and in the mid-90's, no- one wanted to have electronics stuffed down their throat. BMW didn't do anyone any favors in the long term, either, with their closed- shop mentality, and third party electronics. It seemed so cool and high- tech at the time, but instead of tapping a then- interested market, they effectively alienated it and to a large extent, killed it off. So here we are with a dwindling enthusiast market and little support for the part of it that likes to take things apart. "Nobody will fix my car for me!" t end- stage predatory capitalism

    oh. I thought it was going to find itself when I lost it. never mind. get off my lawn. where'd I leave my teeth? t
