POST 1 / ORIGINAL POSTEROriginal post

After retreating to my thinking room, the room in which I don a smoking jacket and puff on a pipe filled with the finest of tobaccos, I had an epiphany. For those less than wise, and less than fortunate in our locales, who enjoy a bit of Porsche driving in the below freezing and below zero weather, the specter of scored bores looms like Harry Weinstein over a young starlet. The horror stories of piston slapping noises and oil thirsty engines are enough to keep one awake at night. Until now. My preventative cure is simple. Instead of just not driving my car, something a common peasant would do, I preventatively drain the oil after every drive into a surigically clean oil pan that I take into the house and put into a specially manufactured heating cabinet that keeps my oil at a tropical sixty eight degrees. When I need to hop in the car for a trip to the shops, or more likely to my job, I simply pour the oil back in, carefully inspect to make sure I remembered to tighten up the oil drain plug, stow my surgically clean oil pan in the frunk and head off into motoring bliss. When I reach my destination I simply jack up the rear end, empty the oil into my oil pan, put the oil pan back into the frunk (which I have fitted with a small space heater spliced into the frunk light wiring, and then go about my day. Now you may say this is a bit excessive, but I firmly believe oil kept warm will lubricate that engine better and help prevent Harvey, I mean bore scoring, from striking. Now we can debate thermal expansion rates and the like, but hey, warm oil is better than cold oil. Also if anyone knows how to affix a snow plow to the front of 996, the advice would be greatly appreciated! Cheers fellas!

POST 2Original post

Seems like a stupid idea. You only mention jacking the rear of the car up to drain the oil. Everyone KNOWS that the car must be PERFECTLY level (confirmed with laaaay-zuuuurs) to drain the oil - otherwise, now, you've left all of the metal shavings in the pan. Duuuuh.

POST 3Original post

Care to share what you are really smoking in your pipe?

POST 4Original post

Pure genius. I�m so doing this. One question: where did you find your space heater? I�m having a hard time finding one that fits, and more importantly, one that is Porsche approved.

Shooot. I forgot about those shavings. Well, my car is 19 years old, so I suppose it�s no longer peach fuzz in the oil pan, but real, grown up shavings. Guess I�ll have to rethink how I drain the oil now...

POST 12Original post

I know this is said in jest, and I get it. When I flew small piston planes in Alaska, it was common to drain the oil from the engine into a 2gal jug and take it inside to keep it warm. When we had to go take a flight, we'd heat the oil and pour it in the engine, rotate it a few times by hand and then start it immediately. Starting a very cold engine with cold oil is pretty harsh on airplane engines.

POST 13Original post

Quotes source post: 14733277

are there not block/engine heaters for planes like you can get on cars?

POST 14Original post

Quotes source post: 14733582

Yes, there are various methods for keeping it warm. However, not all places had electricity close enough to the plane, and other places might have 4 or more planes tied down overnight. We couldn't all use the same power feed or it would trip the breaker. There are also pre-heaters that use LP bottle, or kerosene. Not all places had them.

POST 16Original post

I should have chime in with my method while you guys try to do something crazy. People in Asia has long discover the power of electric spoon. We have these when schools ban food cooking in the dorm room and when your roommate keep the microwave dirty. I have made many raman noodles in the middle of the night when studying. We also take these with us when going to hotel resorts to heat up milk in the middle of the night for kids and make noodle soups when there is no microwaves. just drop the spoon down from the filler and plug it in Keep it nice and boiling hot.

POST 17Original post

wonder if someone could just design an aftermarket oil pan that has a small built in heating element that can be powered either internally (12v) or external 110/220 .. if you werent at home, you could have an option to turn it on 10minutes prior to starting (12v) , or, have it at a constant temp overnight if plugged in externally (110/220). :-) kinda like the big diesel trucks with heaters in the blocks.

POST 18Original post

We've got the option of block heaters in John Deere and Caterpillar engines and gearboxes, turn on three hours before start up or leave on all night. One friend worked harvesting in Canada and they told him if he broke down the machine would have to stay there until the next April when it might be warm enough to fix and start.

POST 19Original post

ive seen a bunch of those survivalist minimalist tv show guys (alaskan long haired people, crazy lumberjack hunting dudes, etc) where they start small fires under the blocks of engines (keyword: small) to get the oil/motor warm enough to start up.

POST 20Original post

Sorry, but only guys who care nothing for their cars re-use their oil in this fashion. After every drive I too drain the oil, but before the next trip I put in all new specialty oil that I cannot tell you the name of because it is made of actual living dinosaurs grown on an island in Costa Rica. How do you know the help isn't "borrowing" some of your nice warm oil to put in their lamps at night to read by? All joking aside, we had rain for a couple days here that seemed to wash the salt away so I took the car out. And now I feel guilty, which makes me a loon.

the damn help stealing oil! That explains why I�ve had to add a quart every thousand miles or so!

POST 22Original post

I'm late to this thread, but can relate to both methods: My dad is 88 this year and when he was a kid, a Model A was a typical used car. Tells of the neighborhood mailman (this is northern North Dakota mind you...) who indeed drained the oil out of his A every night, took it inside and poured it back in come morning. The mail's gotta get out! Back when I wore a younger man's clothes, our yard tractor was a JD 730 diesel which had pistons the size of cans and plenty of compression. It was too new (!) to still have the gasoline pup engine for starting, relying solely on electrics, don't ya know. Clearing snow was (still can be) a life and death matter, so we would throw a heavy canvas tarp over the front half of the tractor, get a couple nice logs from the wood pile, and light 'er up. The trick was to position the tarp to avoid melting the front tires. The paint was a nice black to dark green fade job on the frame, but she started many times using this method. I also remember using a tarp and pointing a salamander heater at the engine on the combine once, but that was our fault cuz we didn't work hard enough to finish harvesting before the Alberta Clipper arrived that year. Plus it was an "easy" one, cause the combine was inside our polebarn at the time. Man, if the old man caught us starting a car or pickup in the dead of winter without having it plugged in, he would tan our hides.

POST 25Original post

We (the Royal we) would take our tanks out on exercise in the winter when ambient temps were -30 (C or F, it is the same) or colder. For weeks at a time, we would not turn them off, not even to refuel. We would do "rolling replenishment" where the 2 x 800L fuel tanks would by hand filled, 20L at a time while the tank crept along. So the answer is to just keep the engine running from November 1 - April 1. Ideally you should just keep driving it, 24/7 through this period.

POST 29Original post

I worked with an older mechanical engineer several years back. Every day before leaving work he would walk over to the window of our 3rd floor office building with a remote. I asked him what he was doing. He had installed an external pump, heater, and piping inside the engine compartment of his Buick Roadmaster. The oil would be up to temperature and parts lubricated when he was ready to leave. He did this summer and winter. Come to find out he was an ex Porsche owner, mechanic, and driver. Drove 356's in the 60's; one of which was a 356 Carrera. He said he would rebuild the engine in the kitchen of his apartment when he lived in California. He sold the two he had after a friend was killed driving a 356. You never know the knowledge a person has or their background until you talk to them. This guy was somewhat of an inventor/genius when it came to mechanical fixes. He was also a metallurgist.

POST 32Original post

I hate to admit it, but the first thing I thought is; do you keep a spreadsheet on the door of the refrigerator in the kitchen with oil temperature on one axis and outside temperature on the other? If you want the oil to be 68� when you pour it in, you have to account for the loss of BTUs as you transport it through the cold outside air. The colder it is outside, the higher your initial temperature will need to be. These things are important!

POST 37Original post

This guy looked a fair bit like my Dad did about 50 years ago, that is until he took his beanie off. He was pretty scientific about the whole thing. We just made a campfire and went back inside for peanut butter sandwiches and Kool-Aid. We also didn't make any Hindenburg grade sparks when we jumped something. Yikes. (Once our neighbor was fueling a gas tractor from his elevated tank when a wrench fell out of his coverall pocket and landed on the batteries (the seat which normally covers them on a JD being missing at the time) which sparked like a Rocketdyne F1 engine on pre-ignition, which then lit the gas hose on fire, which then (just like a Wiley Coyote cartoon) burned upward and lit the entire 300 gallon gas tank on fire. Well, actually it exploded and shot across the entire farm yard at a steady eight foot elevation, went straight through the open doors of their quonset, and landed in a huge pile of newly harvested wheat. Which it lit on fire. Alvin was standing at the kitchen sink at the time when he heard a faint noise and looked up just in time to see the conflagration shooting across the yard in front of him and disappearing into his quonset. Too bad we didn't have cell phone videos and YouTube back then.) Oh man, just typing that out is making my wife wonder why I'm over here chuckling uncontrollably... Nothing fun ever happened over at our farm. Anyway, rural folks learn the difference between what is easy and what is possible pretty early on.
