How accurate is your Oil Level guage?
#31
I agree with everything you say there Bill , it takes a bit of time for the oil temp to get to the 3 o' clock temp (approx 230f , when the low fan kicks in) but it's at this temp that I find my oil quantity gauge works best.
You won't see that 230f temp unless the car is sitting for 10-15 mins with the engine running , after the oil has come up to the 194f level for the second time (ie the oil cooler valve has opened)
Crikey , it really isn't that complicated ! .. Sorry for making it sound like it is!

I think you mean 9 o'clock on the temp gauge (unless the location is swapped in Ireland). Unfortunately (or fortunately in my opinion) my car rarely sees 9 o'clock and I'm not going to try and get it up there, other than in spirited driving, if I can help it.
I think for all practical purposes we agree on the procedure, just go about it a little differently.

The gauge is operable. But in order to bring it up to the 3 O'Clock position, I would need to top off the oil, which I don't want to do, as any amount over mid point is quickly consumed.
Given that the guage operates, is the sending unit still suspect? Is there a way to calibrate this?

If it gets to the 230F (9 o'clock position ?) I'm not concerned about it, however, since mine seems to (normally) run cooler than that I'm happy. Personally, I wouldn't start getting anxious until it got to the mark at the 10 o'clock position. I think mine's only been that hot once and all I did was check to make sure the oil lines to the cooler were warm (indicating the thermostat was open) and that the fan was running.

Very bad idea. This advice is best not taken.

I got slapped
For the record , this tip was given to me by a Porsche tech with 17 years experience , so he was weened on air coolers. The reasoning is that it gets the car up to oil fan/level testing temps quick without running the engine on idle for longer periods of time... I wouldn't see a problem as long as you kept an eye on proceedings ..
But I'm no techie , so I'd be very interested to hear why this would be a bad idea ..

The reason it's not a great idea is simply that an air-cooled motor relies on, well, air to cool things like the cylinder heads. Sure, putting a blanket over the decklid grille will heat up the engine quicker, but you might also end up with hot spots on the motor. Especially being that getting a 993 motor up to temperature the old-fashioned way -- by driving it -- is not all that difficult a thing to do.
