There's another reason to measure at the cam: on my '72 tii, the valves stems had worn into the eccentrics which made the measured gap smaller than the actual gap, since feeler only measured across the high edges of the divots. The 1.26 rocker ratio factor I understand, but owning bimmers...

Respect to those who have responded with regard to my thoughts about whether polishing would create distortion. I are engineer, so I may be "a little dogmatic" about this small matter of physics. Hear me out... One: the glass depth removed by polishing would be very small. Thus any...

The bumper under-riders are cosmetic. So is the bumper on early cars.

A neighbor tried several times to create a fiberglass hood for his '55 Chevy. It warped each time - suggesting that "all" glass items have the capacity to do so. I used to do a bit of work (a lot, now that I think of it) with glass. Polyester resin (the most common) has is a considerable...

Shops that can do the balancing you're seeking seem few and far between. One suggestion I've heard is to try a truck service shop - lots of trucks use multi-section driveshafts. Another: I spoke to Carl Nelson in '95 and said I'd re-used my auto trans dshaft for my 5-speed conversion (I...

You'll never know until you install and watch an oil pressure gage. Some decade or two ago I put an oil pressure gage and sender in my 2002tii (roached it from a VW) and was quite surprised at the high cold idle oil pressure, and low hot idle pressure. Generally IIRC you want 10 psi increase...

Holdonaminnit. Brake fluid simply pulses back and forth in the M/C, lines and calipers. It doesn't, strictly speaking, "circulate". Blood circulates in that it passes through separate pipes outbound from you heart, through your system, and then back to the heart via different pipes. At least...

Below is a collection of stuff regarding 32/36 carbs that I collected over the years. I have not verified any of this but all together, the stuff might represent a consensus of opinions. I also have a bunch of similar stuff for the 38/38 carbs 32/36: f7 emulsion tubes, 140 to 145 primary...

apologies to the Mel Brooks lovers. I haven't named my CS though it's outlasted several dozen other cars including Whizzer (2002 325xi named by daughter), Ruffian ('94 E34 named by me because the license plate started with RFN) and Green Flash (wife's '98 C280, because of it's brilliant, stock...

jmackro, no diz but are you sure that a deep polish would make the windshield optically incorrect? Seems to me that if the glass is optically clear, thickness variation won't matter. Trying to get this through my head. I have seen optical warble in windshield glass, never put too much thought...

Just happened on a video showing a sulfamic acid solution used for getting old yellowy-brown coolant overflow tanks back to translucent white, but there's no/insufficient info about the effect on plastic. Anyone used this stuff? What were the results? the video: background info...

also share the spring free length, number of coils, and spring compression rate (asking for all the secrets, I know).

1. Jack it up, block it up, crawl under with raincoat, goggles, face shield, water hose, scrub brush. 2. Find a pit, use it, bail it out. 3. Don't really know how high you can jack one side, but would be a very dicey approach to raise and support with reliability. 4. Find someone/someplace...

Watch out for euro gages that show pressure in kPa (kiloPascals). 100 kPa = 1.0 bar = 14.5 psi

It might be useful to remember that Benzes of that era used the same dimple keys, so wherever the M-B guys get theirs, we should be able to also. I expect there is a standard somewhere for dimple x-y spacing. The dimples themselves come in (IIRC) three sizes/depths. I had a key cut here in...

My somewhat OCD/hoarder neighbor photographer Mrs. C. has several dozen translucent plastic filing boxes for all her stuff, with printed labels on the inside of each.

I just got another email from Hagerty, who cover my CS. Hagerty will have an online presentation by and including Hans Stuck, Brian Redman and Sam Posey, September 12 at 1:00 EDT. The announcement is here...

stphers... I was kidding. A little bit. But there ARE at least the number of ways I mentioned for fuel smells to get into the cabin.

This is brilliant and easily constructed; also may allow aftermarket seats to fit.

Re the (split, unusable) bushing on the steel sender pipe - suggest you remove and dry the sender, then put on some heat-shrink plastic hose, as used in the electronics. Next, yes the o-ring is supposed to dry out and "restore" overnight. Lotsa luck with that; new ones are relatively...
