I just bought a nice 1980 911 but I have a few questions. While driving it I figured that the OEL gauge meant oil level and that druck press meant exhaust manifold pressure. Am I right in my assumptions? What's with the naming scheme? Also, the clutch goes down like a foot but only 2 inches or so is needed to engage the thing! What's the deal with that? About how far down do I need to press the clutch so as not to slip the plate?

I'm sure I'll have more questions in the future. Thanks for any replies.

OEL gauge is the LEVEL of oil in your oil tank. The DRUCK is actual oil PRESSURE. If this is your first Porsche, the procedure for checking oil is very different than your average vehicle. Check the oil with the vehicle running on level ground at operating temperature. Read these boards and you will learn a great deal about your car.....And enjoy!

your druck should be one division per 1000 RPM, just a rule of thumb.

Your clutch engages just off the floor....sounds good...2 inches.

I think what you meant about the clutch is that you only need about 2 inches from the TOP before it DIS_ENGAGES and yet it can be pushed much farther toward the floor needlessly-is this correct? If so, you can adjust the pedal stop point. I just did mine for the same reason and it has made it much easier to shift smoothly and alot less effort. Just remove the carpets to expose the pedal box. It should have a 1/4" wooden cover protecting the area. You will find 2 allen screws with washers straddling the clutch pedal arm-loosen these and a bracket with a rubber stop will slide DOWN. Start with it all the way down and tighten-your clutch pedal should stop much earlier now. Test it and adjust until it engages about 1.5" from this stop.

Please help with two questions, which has been with me since buying my first 911 two years ago.

If the OEL gauge shows oil level and the druck pressure shows oil pressure, and if they are both in the normal range at operating temperature, why is it necessary to check the oil?

Secondly, the OEL level is always at the bottom, in the red zone, when the car is cold, is this normal?

Thanks very much.

I think your second question answered your first. I have never put a lot of faith in guages and warning lights...they're helpful, but not the final word. Since oil is the lifeblood of your car, best to go to the source to make sure it is right.

Unfortunately I don't speak from 911 experience (yet), but many years of 60's Bugs put me in the habit of manually checking the oil at least once a week. I won't say the cars are the same, but the underlying principle is the same...

George,

The oil level gauge shows an approximation of what's in the tank. You want your oil to be roughly half way between full and fill on the dipstick, when measured on a level surface with a warm engine. Never, ever, fill the oil tank based on the oil level gauge.

It's normal for the oil level gauge to stay in the red until the engine starts to warm up. It's starts moving up maybe around 150-160 degrees. 180-210 degrees is the normal operating range.

Mr. Gregory, thanks for your help with the oil level question, and the oil temperature question.
