Differential Types - 2002 and 320i:
Early 1600's and 2002's came with a long neck differential. These were phased out in early 1969. They were either 4.11:1 (1600) or 3.64:1 (2002). They are very rugged (heavy) and easy to come by, but not rebuildable due to the lack of available replacement parts. If you want to switch to the later short-neck differential, you must replace the entire subframe and rear suspension. This sounds tough but is actually fairly e
I wanted to make this a separate thread from the long one about my fixing Brian Ach's rust-contaminated tii to make it easier for other folks to find the pertinent information without having to look through pages and pages.
Pursuant to the other thread, I was trying to nail down a rough running problem in a tii. It eventually turned out to be four rusty injectors, one of which was internally broken, but before I knew that, I convinced myself that rust in the fuel had created a "stuck piston" in

I have decided to go a different route then most and install two indivual throttle bodies (ITBs) instead of a single throttle body and plenum type system. So far everything is working great based on Speed Density (Maifold pressure reading) which many thought would not be possible. I also have a more agressive cam with no overlap which probably makes the situation easier (278 duration, .288" lift). More information to come as I install EDIS spark control. Until then
On the way to the SoCal Vintage BMW Meet the new to me car was overheating when reaching highway speeds. The drive was a bit painful with multiple stops to let the car cool and took forever since i had to keep the car at about 80km/h. We didn't get to Santa Barbara until after 1am. Early morning and slow drive to Van Nuys followed.
The plan for the show was to set up the tents, put the cars in place, and then find a suitable radiator.
By the time we made it to Woodley Park, Ray from Elefant Su
Using this Google spreadsheet developed by Grice Mulligan, AKA williamggruff, users and abusers alike can investigate the outcomes of matching various BMW transmissions and differentials, and calculate a variety of RPM and speed values that result.
Inputs are simple: Tire circumference and Redline RPM. Tire circumference can be estimated using the link provided. Redline RPM can be a target RPM, such as a preferred RPM at a cruising speed.

There are basically two different types of mechanical fuel pumps that were used on '02s. The '02 fuel pumps have 8mm inlet with 6mm outlet hose fittings, and one that has 8mm in and out hose fittings that is a performance upgrade......
#13 31 1 252 506 Pump is defined by its lever type operating mechanism that is below the mounting surface and the 8mm inlet and 6mm outlet hose fittings. This pump was used on single barrel and 2002 TI's before mid '72.

If your shifter is a bit looser then you'd like, and you want it to feel like new again (do you know how it felt when it was new?) here are a few simple and very inexpensive things you can do to get the like-new effect. This article is based on a late 2002 style shifter. Please look at what yours looks like before ordering parts.
Part list:
Few more parts needed (don't have them yet): 8 Spacer ring 25 11 1 220 199 9 Circlip 25 11 1 220 379 10 O
Some basic information about the Solex 36 - 40 PDSI or PDSIT. Jets, parts and tuning. Most of the parts are no longer available, but the rebuild kits can be found all over ebay plus many 2002 parts vendors.
Solex 36 - 40 PDSI and PDSIT were available on the early 1600, 1800 and 2002 models. PDSIT is an automatic (water) choke version and is hard to find. The venturi and jet differences are listed bellow.

I've seen several mentions of plans to use the 320i inner cv joints when installing a limited slip diff from a 320is but didn't find any posts about how it went. Most were aiming to avoid both using spacers and redrilling the diff output flanges. I was only concerned about avoiding the latter. I decided to take a few photos along the way to document what I found. There are lots of articles about other aspects of the swap so I'm just focusing on the dimensions of the axles below to supplement wha
My son and I completed the installation of an electric fan in our 1970 Chamonix 2002. As with most things with this car, it wasn’t particularly difficult. It did require a little research (on this site), access to a couple of wiring diagrams, a small pile of parts,and a modest level of problem solving skills.
There is an excellent “how to” article by Zenon Holz at this link http://www.zeebuck.com/bimmers/bmvseite/)and a great wiring diagram from Shaun and Zenon at this one: Electric Fan Wiring
If you have an oil leak from the front of the engine, it may just be the front main seal. You should first rule out items higher on the engine like the valve cover and the timing chain cover, but once you decide it's the front main seal, replacing it is relatively easy. This is a 2-3 hour job depending on whether you have AC or whether the old seals becomes a PITA.
This job can be performed without jacking up the car but you might as well put the car on jack stands or ramps just in case the job
When i got a hold of my touring, it came with a canister style oil filter. Since it needed an oil change a few other things to be drivable i had to replace the filter with the style that every one else used. But now, since I have a nice stash of the filter replacements i put the parts back together to get it to be more original.
All part for maintenance are still available, so putting things together was not a problems
Filter itself
It came with a card

Rebuilding the Getrag 232 Four-Speed Transmission
Parts Needed:
Transmission seals kit
Transmission gaskets kit
Transmission bearings kit
We are working on getting part numbers for all these parts and kits. There is also a lot of information about pulling and replacing the tranny itself in the Five Speed Conversion article (see Index).
[Editor's Note: This Article was put together from several of Mike's posts on Roadfly, and should not be taken so
Need to store or transport an M10? Need a way to support it on its side properly? Here you go. I spent a little time today putting together a wood stand that supports and M10 laying on its exhaust side. Then mounted it to a board with tiedowns that lays in the back of a pickup bed.
What you need:
Some 2x3 stud
Some 2x4 stud
3in drywall screws
Saw
Drill
Start with the studs and build this. All the measurements are in the pictures!
note the notches in the 2x4.
It fits against the engi
for those with M2's or E30 M3's. step by step on doing valve lash adjustment.
I will skip the obvious that you have to pull the plug wires, valve cover and spark plugs off..
First you need tools.
Feeler gauges, micrometer, bmw valve bucket depressor tool, magnet-on-a-stick, small pick, air pressure source and bicycle pump nozzle, light, paper/pen and magnifying glass.
For each set of valves..
Rotate engine so that the lobes are pointing away from the valve shims
Measure the gap on both
Tools:
Small Hacksaw (Junior Hacksaw @ Homedepot)
Hammer
Large flat-tip screwdriver or Chisel
Overall this took me about 10 minutes once I finally got started. First remove the blade from the hacksaw and push it through the open section at the bottom of one of the hanger bushings. If you can not get it through on its own, a sharp knife should help. Next reassemble the hacksaw with the blade through the bushing. Now use the hacksaw to make some room by cutting the bottom nub of the bushing ou

razorblade (to scrape old gasket)
NEW paper oilpan gasket and ultra grey sealent (Paper gaskets wont seep like the cork ones do). They are available at any independent shop but will have to be orderd. I can get them if you can't.

After you remove all the SMOG krap , fit a new mechanical advance distributor, adjust valves, test compression, new plug wires, plugs, ignition timing set using a TIMING LIGHT , change all the fluids, wash and detail the car (that's good for a few more HP's!), and my WEBER 32/36 Jetting Prescription (actually over the counter and CHEEP!)your MPG and performance should improve.
