78SC Injector Lines and Winter Checklist questions....

[acapella8]

Being in the midwest, and it getting colder, and....

Reading Souks thread about richening the idle mixture....

(which I think I know how to do now with a long 3mm allen)

I learned I have plastic fuel injector lines, to me that sounds like a recipie for failure at some point, - but maybe I'm missing something.

1. Can I replace them to the pre-formed steel lines that apparently came along later for the 80 series? Is this something a very new to P-cars but moderately decent at following checklist type of guy can do? with

2. Has anyone ever developed a "winterizing checklist" for the colder climate p-car owners? I want to try the idle adjustment screw tonight, along with a host of other small things.

I really dig checklists...

I guess the lists would be slightly different if you were going to drive or store your car over the winter. Sounds like you are planning on driving it, so I would:

Monitor your start procedure to see if it is going well. If not, check the mixture as you mentioned. , as well as air leaks, and proper function of the CSV, AAR and AAV. My car, w/ no O2 sensor, requires about 1/8 turn to richen in the fall, which I set back in the spring.

Go to a lighter weight oil

Make sure your tires are up to the conditions. Keep the pressures up, as they go down w/ the temp.

Make sure tuneup items are good, eg wires, rotor (if app), cap and plugs

Put Vaseline on your Fuchs

Put glycerine on your rubber seals

Make sure your brakes are in good shape

Check your lights, turn signals, power windows and heater for proper function

Make sure your battery is in good shape and keep a starting battery in the trunk.

Make sure your spare, tool kit, and air compressor are good

Lube areas that require it

Keep a cell phone, AAA card, candles and lighter , blanket and some candy bars in the car.

As far as the plastic lines: they last a long time, but they can break when cold. I had one go that was probably about 23 years old, so I would recommend replacing an old set. I don't know what the cost of steel lines is. I have new plastics.

I hope this gets you going. I am sure others will add to it.

I'm DEFINITLEY planning on driving it!

Thanks Paul - a great start to my checklist, I'm sure others will add.

What does vaseline on the Fuchs do? Prevent Aluminum oxidation?

Just joined AAA,RV+, and got a coleman jump-charge/air compressor etc. Tune up happens (oil, plugs, fuel filter, cap) this weekend too, along with the mixture richening?

Yes, the later style metal fuel lines will fit as a repacement 78/79, you might need to get the little plastic holders that keep the metal lines held in place to each other too, I ordered my metal lines from porsche direct through a new car dealer, expect to pay between $12- 35.00 per line as each one cost a different price. As I remember there could be one out of the 6 that is NLS (no longer stocked) but the coresponding line from the other side will work if you bend it alittle. The rear lines to the fuel dist. will have to stay plastic because of the different Cold start config.

acapella,

Put the vaseline on the clear anodized part of the wheel. Rub it in. Leave it on, say overnight, and then buff off w/ a cloth. It gets into the pores of the aluminum and keeps everything else from getting in.
