Dumb question
 
ok ok I've owned my '79 for 34 years but am not mechanically inclined so forgive me - I read that after storing a car for a period of time (in my case it will be 4-5 months), a smart thing to do is to turn the engine over without spark in order to get oil moved around through the motor without actually starting it. Ok, makes sense - how exactly do I do that with my '79?

Thanks

Jason

Don't bother. 3-4 months is nothing. Put some STABIL in the tank before storing, run the car a bit, hook up a battery tender, over inflate the tires and head to Florida.

If you want, I'm local. I could drive it around the block every once and a while for you!SmileWavy

To answer your question, pull the coil wire. I'm not sure I'd say 4-5 months of no-start is a "long" duration to cause an issue though.

Anyone who lets their 21 year old drive their 911 when they're not home is either very trusting or has a stalking device hidden in the 911.:)\

BTW, most of my cars sit like this for months. Not a big deal. If you're talking 9 months or longer, that's an entirely different kettle of quahogs.

Thanks. Is it straightforward to pull out and then replace?

sometimes you have issues when driving the car, actually using it... and sometimes when just storing it... :-)

4-5 Month is nothing. just start it and get out and drive.

Engine pre-start up prep.........
 
Jason,

Four months is not that long but to feel better you could disable the ignition and the fuel pump. Disconnect the ignition coil primary cable and the fuel pump relay. If you don’t disable the FP, you will have raw fuel in the combustion chambers delivered by the CSV during cranking. And the next time you start the motor with the ignition activated, you will probably be surprised by an unexpected backfire.

If he is not mechanically minded he won't know how to disable the fuel pump; remove fuel pump relay in fuse box in the trunk - it's the red one. And it can only go back in one way so no need to worry about getting replacement wrong.

a long time ago I had my room mate do this as I traveled a LOT, a trans am not a porsche yet.

That is not really a dumb question.

A dumb questions is "Do you guys like air cooled 911s?"

As others have said, don't worry about a 4 month storage. The biggest enemy is old gas. Keep the tank full and use no ethanol if possible. And be sure to drive it long enough to get it up to full engine temp or as warm as possible if it is cold outside.

Thanks, it's what I've been doing for 33 yrs, but having just read the suggestion recently I wanted to ask the Q.

Thanks Glen - avoiding ethanol is not easy around here (Long Island) ...

Thanks Tony - good luck with the engine workshops!

I said he has first dibs - I didn't say that he drives it ... :D

Bill Douglas 02-11-2020 10:22 AM

Jason, I'd just put one of those trickle battery chargers (Ctec) on it and not worry.

boyt911sc 02-11-2020 10:41 AM

Which one?

But they all look like the same color!

Jason

so, if it will be driven periodically, it won't be idle for months at a time.
No precautions needed IMO
(except a stern breifing for the 21 year old...)

The coil is the cylindrical shaped item that is mounted to the front top edge of the fan shroud. Remove the wire from the center post. You might have to wiggle and tug on it to remove it. Reinstall by pushing back in.

Simplest method of keeping the kid out, lock the car, and keep the keys in a safe place. I keep my 911 locked and parked in the garage. The only keys easily accessible are in my pocket except at night when I am in bed. All the other keys to it are locked up. And I have no kids.
