this morning, and she fired right up!!

pumped the pedal 3 times, set it at 1/4 of the way down, one glow cycle.

I didn't need to go anywhere, but i was outside getting the Big Booster for the neighbors who's suzuki wouldn't start. Decided to give it a try. Glad I dont need to do that everyday.

I didn't know this was the Mercedes Sci-Fi forum. To believe that I would need affadavits' from 3 witnesses. Possibly a blood and skin sample from said witnesses. Video and oral testimony would also be needed.

Does pumping the pedal do anything?

It does on a carburator due to the pump inside the carburator.

is this with or without a plug in heater?
-22... brr. F? Holy frejolies!

I am still in america, I think??- so that is -22*F.

no block heater, or I wouldn't of bothered posting. synthetic oil, proper timing, valves adjusted, and 400+psi all helps.
I will say that last winter I had an instance where it did not start at slightly higher temps(lower -teens), but for whatever reason, she lit off today.

I dont really know why we are supposed to pump the pedal-maybe to free up all the linkages?
but that is what the OM says to do.

I wont be offended if ya'all dont believe me, I know what really happened. and I'm sorry your car doesn't start as well.

fwiw, this car has been burning WVO (2 tank) for about 50K miles, too.

stay warm. keep your stick on the ice.

I feel sorry for you. How can you live somewhere that gets so cold?

Yeah, it's great that your car started right up, but geezaloo! -22!

Those are the compression numbers you'd see on a new engine. Is yours rebuilt? Nonetheless, still an impressive feat!

i just ran 20x50 cause the motor has lots of miles on it.

or what do you run ? in high mileage cars?

thanks

I do........it's not spinning fast enough.

It's OK in the summer.........not OK in the winter.

5W-40 synthetic..........all seasons.

Awesome Mo. When was the last time you started it before this afternoon? If you fired it this afternoon it wasn't -22F was it? I thought it was in the single digits this afternoon.

Mine didn't start this morning. I even had it plugged in, but I don't think I was getting much juice from the outlet. I did cold start it at -3F last week. Then today after it fired fine the rest of the day sitting in the cold, but it was warmer later today.

My Webasto was out of gas as I didn't think I would need it since I knew I'd be plugging it in. So I pushed it into the heated garage and let it sit for a bit, then it started.

EDIT: Just saw you stated this morning, not this afternoon. Guess it really was -22F. My temp gauge read -27.5(C) this morning. Tonight on the way home it read -25.0C

So what was the temperature of the garage you had it in?

mobetta · #13 01-15-2009, 09:44 PM

she'd been sitting since sunday while I waited for another pair of calipers.

It was this morning- I looked at the thermometer and it was at -22, then I helped the neighbors get their car started, then tried mine- so maybe it warmed up a degree or 2 in the meantime.

and by single digits, you mean single digits BELOW zero. we haven't seen the friendly side of zero since monday. but sunday is supposed to be 30*F, almost record breaking.

A friends 300 didnt go this AM either, even plugged in 4 hours. his compression is all over the place, though. 170-380 psi, seems to have stuck rings??????

I have no records of the car previous to 266K when I got it, so the engine may have been gone over. I have no reason to think that it has, but the Timing chain shows almost zero stretch w/ dial gauge, but I did not pull the cam pulley to see if/how far offset the key is. and the phenomenal compression.

My car did have a webasto at one time, so maybe it never had a cold start for the first 250K.

Ryan- the webasto wont help w/out fuel!! glad you got it running again.

I will say that oil makes a HUGE difference. I had no start at +7*F with 15-40 rotella. of course, that was my first winter driving a diesel benz, so some of it could be operator error. but I drained it later that day and had (almost) no more issues with synthetic oil- 0-40 M1 that year, now 5-40 Rotella.

also - one of them cheesy jump boxes has saved my bacon more than once- worth every penny of the $20 on spring clearance.

Yes, I meant got up to single digits BELOW zero. We haven't been above zero since the beginning of the week.

As soon as I got it running yesterday I stopped and filled up the Webasto tank!

-34 Celcius this morning in eastern Canada, about -30 F.

The BMW started but the 300D is parked in her warm garage until spring!
