grease for a window regulator

This is about window regulators, specifically on my 1980 300SD (W116). The drivers side window regulator is broken, and MercedesSource has a new replacement for it, but no instructions available with the new part. After examining the broken regulator, I believe that a lack of grease (or lubricant) on the regulator slides contributed to the failure. Further, my other windows are moving slow or binding up, and I suspect that lack of lube is responsible for that slowness as well. Trouble is, I don't know what grease to use on the regulator mechanism. Grease isn't just grease. It's formulated to work at a certain temperature, under specific conditions, and I'd bet the grease on a window regulator is altogether different than wheel bearing grease, for instance.

Diesel cigar shaped fuel hose

Hello forum, I have just purchased a 1981 300D - non turbo, 100,000 original miles and I am hoping to run Biodiesel, not svo/wvo. In looking over the fuel lines, my mechanic told me that the thick bloated looking line immediately before the canister fuel filter was that shape as a "damper". I haven't seen any kind of chem resistant hose in that odd shape. Is there a specific replacement for this piece or will other hoses serve the same function? Thanks, Dave

1975 230 parts help

I bought a decent, very original 230 sedan a couple weeks ago. Overall the car is in pretty good cosmetic condition but the engine needs help. The compression is below the minimum at around 100 to 115 pounds. It does run but it's pretty weak. I've searched online but haven't been able to locate a source for parts to rebuild the lower half. Pistons, rings, bearings seem to be a rare commodity for this engine. Is there a source I've missed or are the parts just difficult to come by?

Driveline or engine noise? Help.

The date is March 12, 2007. I get a strange sort of metallic noise that seems to be temperature aggravated. It seems to be engine RPM related, but I can't be certain. All winter I heard it, most at AM startup. I don't think it goes away at speed but can't hear it over other engine and road noise. It seems load related. At 25 mph in town it could be aggravated by light throttle pressure and sort of disappears on no load with a matched speed and throttle. I live in Fallon, NV, so it was cold. The last couple of days I have been in Blythe, CA, and it has been very warm - about 90.

1969 300SEL won't pass emissions.

The Carbon monoxide was way too high, so I took it to an import specialist and he's saying that I need a new fuel injector pump. It's not the fuel pump, but the injector pump. The mechanic said that these are not very adjustable and I need a new one - which he said costs around $1600. Yikes! Does anyone know any tricks to adjust these so I don't have to buy a new one? Or maybe the problem with the emissions is somewhere else?

240d impossible start on the coldest day in winter.

So I just replaced my glow plug timer relay with the manual override and everything was working fine until today. I got out of bed to find that the temperature outside was -3f. I cycled the glow plugs for 30-40 seconds and tried to start the car to no avail, not even while holding the glow plug button and pushing the accelerator halfway down. I couldn't get it started and got a ride to school. When I got home at 3:30 I found the block heater and plugged it into an extention cord from my house. I let it do its thing for an hour and then tried to start it again with the same effect. I'm pretty sure the block heater is working because I opened the hood and could hear it making a humming sound.
