Porsche Crest winter-time oddness?

I broke my timing belt about a month ago, and after two weeks of my car being in the shop (and $1900) I finally have her back. They replaced the timing belt, valves, hoses, etc.

This is also my first winter with my '83 944, so i have some seasonal paranoia.

I'm wondering if it just takes awhile for my car to warm up or if there is a problem. She starts up fine and idles alright... maybe tiny bit rough. But once it's warmed up, runs perfectly. If I don't let it warm up enough, i get an odd sound coming from behind the steering wheel. It sounds like it's in the heater/vents or something. It's kindof a clickity sound -- not like metal on metal clickity, but more like a vent of some kind. After a mile or so, it goes away.

Any thoughts?

Actually Bryan I have a similar thing, mine is the clutch when cold, it chatters a bit when its in for the first mile or so then, once the metal bits get warm and expand, the friction ceases and the noise goes away.

As you seem fairly new to 944 ownership you may not have heard of the two most important things to remember:

1. Every 944 makes a unique 'strange noise' most of which cause extreme worry but in many cases are nothing to worry about at all. - don't beleive me? do a search for '944 noise' or 'strange noise' on this forum and prepare for a lengthy read!

2. Every time you repair the one thing that is not working, something else will go within ten miles or so. Some people refer to this as interference from the 944 gods!

to be serious, I don't know what your noise could be and have discovered that it is very difficult to identify a fault from a description of a noise because if you don't know what you're listening to, how can you describe it?

If you know the part thats making the noise, you can describe it easily, but you will no longer need to post it up here because you have identified the fault

Catch 22? no, catch 944!

Don't worry buddy, on the whole these cars are fairly bullet proof, just make sure the belts are changed regularly!!!

You did very well to get a bill for $1900 too, there are peole on this board who have paid more than $4k to repair broken timing belt damage!

I've never had a car that didn't have one or two noises that were unique to it, just takes some acclimation to the car for you to get used to them. My 924S tends to like having a few minutes to warm up also, used to have some stumbling in the cold if I didn't let her warm up, but after I changed the distributor cap/rotor, plug wires, and spark plugs that stopped and she's better about really cold starts.

Thank you guys for the reassurance. I've only had her for about 7 months, so everything i hear makes me nervous.

We just got 3 inches of snow last night, so i'm gonna dig out and see how she handles on ice. I'm going to put about 3 bags of sand in the back to see if that helps out.

She should be very good in the snow. I had no problems driving around Pittsburgh on a day when the university was closed from too much snow.

You should hear the noises these cars make at -20.

Heater fan hums, power windows may decide not to work, microswitches on locks become uhmmmmm peculiar, entire chassis creaks and rattles worse than a 77 dodge volare.....

my miles per gallon reads about 20 mpg when started in the winter and idles a little rough, after about a minute it creaps up to 30 mpg at idle and runs fine...


My car was terrible on the ice we had this weekend, not bad in the snow though.

At idle, sitting still, read the little grey numbers on the guage, _not_ the white numbers. The grey numbers give a gallons per hour measure. Ar warmed-up engine tends to be around 0.5 gallons per hour at idle.

And no car is good on ice without studded tires or chains.

lol. I actually didn't catch that earlier. yep, Aaron. no matter how well your engine is running. at idle, the mpg always 0

is it bad to drive immediately after starting, and try to be as modest about the rpm's as possible? does it matter if i let it warm up before i drive it?

the engine does sound quite weird when very cold.

most modern engines do not need much warming up. to the contrary, there is no benefit from prolonged idling and it can actually do more harm to your motor, as the increased time it will take to warm up the engine will increase emissions, causing sludge and varnish to build up in the oil. this will also cause an increase in engine oil acids which will tend to ocorrode engine parts. not a good thing. you were right with your assumption that you should wait until you have sufficient oil pressure and then drive off gently until the oil reaches full op-temp

The Porsche manual for mine recommends (as I beleive Audi did at the time) that you start and drive off straight away but do not exceed 3.5k rpm until temp guage reaches first line. The lotus I also drive comes with the exact same recommendations.

Obviously when the inside of the car has iced up (like mine every flippin' morning) you have to idle while it clears, this does wonders for whipping up a nice early morning oil milkshake mmmm...

Personally, I would not drive my 944 in the ice unless I really had to.

Putting weight in the boot is a really good idea to get more traction from the rear wheels. Sadly you steer with the fronts which now have less traction because the back is weighed down.

944s have even weight distribution, mess with that and you might as well ice skate to work (like satan will the day I sell my 944).

Putting sand bags in the front of a beetle to get more weight over the fronts I understand. Upsetting the balance of one of the most finely balanced cars on the road I do not!

naaah, the traction on the front will stay the same while the traction on the rear will increase. you're not taking away weight from the front, you're simply adding more to the rear. now of course, like you say, that still won't help your steering any
