Cold Start for C60S

Adding to the misery of that battle was the fact they had not been issued their winter clothing, and one guy being interviewed said he moved to Florida specifically to avoid feeling cold again for the rest of his life. It made me think perhaps I should complain a bit less about the winter here!

The long range forecast for this area was a warmer than usual summer. Currently it is 16.9c in the house and 9c on the back veranda wall.

Hi All

First the shop floor is once again dry.

But last night we had freezing rain followed by these temperatures today

6AM -1C
10Am 14C
3pm 1C
Projected for tonight -15C

We will be holding a skating party in the door yard tomorrow when the water that fell last night and this morning freezes.

Cheers Phil

PS Just started snowing

Hi Phil

I have been following the weather you guys in the UK, Europe, USA and Canada are currently experiencing with great interest. When my family decided to immigrate from Holland in 1950 they only had 3 choices, South Africa, Canada and Australia. Australia came up first and that is where we settled. Just think I could have ended up with my but in the snow. I just heard on the news that parts of Western Australia will have temperatures of 50 degrees today, while here we are heading for 37 degrees by Friday.

All I can say is the world climate has gone mad, so I hope you all stay nice and warm and in Oz drink plenty of water and stay cool.

Cheers

Tony

Hi All

Do you remember winters and particularly the WIND CHILL being reported on the news when you were kids being much much colder than now?

The numbers reported 20 years ago were substantial colder, it is not global warming. They changed the system the original system for a wind speed of 20MPH at 5 F yielded a wind-chill of -31F the new system introduced in November 2001 yields a wind chill temperature of -15F. If you take this change into affect when they report record chill have the converted the old record under the old system to the new system.

I stumbled on the change when trying to convert Fahrenheit to Celsius, here is the link to the NOAA web page that explains the difference http://www.crh.noaa.gov/ddc/?n=windchill

Cheers Phil

PS Current Wind Chill Temperature here is -35C old system -26C new system

For 15 years I have been using a very tired M38 CDN as a snow plow. Ugly body, messy engine compartment, low compression, missing all the collectible jewelry sold off to dress up it's restored cousins. This jeep has no reason to keep running but I can start it up and plow to my hearts content at the lowest temperature. It sits in the farm field all summer, then starts right up when winter comes again. A great example of the jeep that would never let you down. A thing of legends.
Yet, so many of us have fully restored hobby vehicles that have trouble starting after a few days of sitting. How come? Brian

Perhaps it's because if the snow plough Jeep doesn't perform it's for the high jump whereas the show pony in the garage will just get some more TLC?

Hi Brian

I think some of the reasons that some older engines (won't call the clunkers out of respect) will start fine and run in cold weather is there very age and the wear. All of the tolerances all through out the engine are large on the older "fully run in engines". As you point out they start and run may not put out quite as much power as a fresh engine, but they get the job done.

I would not want to try and start a freshly rebuilt engine that has been sitting in sub zero conditions. It would be an interesting test to do on a freshly rebuilt 216 vs one 216 with 20,000 on the odometer let them both sit in the cold and use a torque wrench instead of the crank to see just how many pound feet of torque it takes to just turn the crank the first bit.

My HUP and C60L are parked bumper to bumper in an unheated garage the HUP has probably 1500 miles on a fresh rebuild and the C60L has who knows how many miles. If I can get them far enough apart to get between them I might try this little experiment.

When I rebuild an engine I generally put them on the test stand for the initial run. One of the bits of my test stand is a really good coolant heater which is mounted very low so it gets a really good thermosyphon going which if I leave it plugged in over night will get a 216 Chevy up to about 120F. Engines seem to like this treatment and generally seem to start easier initially than engines that were just room temperature. Of course with a 216 priming the oil pump and system with a drill is also part of the game.

I think the other reason those old trucks who sit out in the weather will start in the dead of winter is self preservation they know that if they don't one of the reasons we keep them will be gone. Besides maybe they just like thumbing their noses at the trucks kept indoors.

Phil,
Just another ploy by the authorities to try and "sell" the idea that this is all down to Man and his fossil fuel burning ....... a lot of tosh, we are brighter than that.
