I give up. What is the correct part number for the big screws that hold in the rear seats. The number on the packet is for the too short parts

Now the oil level needle goes straight to the top at idle, and the dipstick reads just above the top mark. I don't track it. Just spirited street. Do I need to drain some oil? Will I damage the engine?
As has been stated you can just let it burn down...and if you have any leaks, it'll drip out. But in the meantime, you are gunking up your intake ...
You want your oil level to be around half way btw the two marks on the dipstick at full hot.
Keep in mind w the oil level, you can drive the car when it's missing a few liters and you'll still be "ok". This is what Porsche suggests when changing the oil- add 7 liters and then go drive the car and get it hot before continuing to fill it. Obviously you aren't going to drive it hard when oil level is that low----but you are safe. When you've added 7liters during an oil change you are 2-3 liters short of full.
So that said...you can be not reading at all on the dipstick and be perfectly safe to drive the car. You can be at the red mark on your dash and be perfectly safe to drive the car. If the oil level is just barely touching the dipstick, you could track the car and have zero issue.
So to the "rookie" in you...your words (I choose to think of all of us as rookies, cuz the car will always suprise the best of us), don't worry too much about perfect oil levels. Make sure it reads on the dip. Don't add much. Only check when very hot. And so long as you are on the dip and below the half way mark, just go drive and be happy.
But if you over fill, you should simply pump some out. And then off to the Italian tuneup...lots of full throttle and heat...to clean it out a bit...

You are way over full. When the engine sits, you are getting oil into the intake after overnight sitting. See if you notice maybe a bit more white puff of smoke when you first start the car in the morning. If so, that's a tell tail sign. You can just stick a transmission fluid pump hose into the filler spout and pump out a half qrt.

> At approx 87C (188F) oil thermostat opens for flow to front cooler.
> At approx 90+C (194+F) or 09:00 position cooler oil temp low fan speed operates.
> At approx 115C (239F) cooler oil temp high fan speed operates.
* Reading at the 10:00 (@248F) position is not unusual when tracking a car

Is your thermostat (bottom of oil tank) opening - just before 8 o'clock position? If when starting and the oil is warming up, you can see on the temp gauge the red needle dropping down slightly when temp is reached and the themrostat opens allowing oil to the front cooler. Can you hear any 'gurgle' down the the side of the car when this happens?
Also check the oil cooler fan is operational. Engine switched off, remove the oil cooler relay (R04) and jump the terminals for both low and high speed operation (live 12v feed with ignition off). If both speeds are working then fan operation all good. If only high speed working then ballast resistor (hard to get at) is dead. Swap the oil cooler relay over too if you have a spare one, just to be sure it's not a faulty relay.
Next up might be a CCU problem. The CCU sends a signal to the relay for fan speed control based on cooler temp reading. My own faulty CCU isn't controlling fan speed at the moment, but even without this my higest ever temp reading from hard mountain course driving only ever reaches the 9 o'clock position.
Your oil pressure reading seems (abnormally) low too(?) Can't see the rev counter needle at idle either. Low working oil pressure and high oil temp - might want to get your 964 specialist to have a look. What oil grade have you been using?
Hope this helps.

Thank you for your reply.
Thermostat opens correctly.
Engine was off, pressure indicator doesn't start form 0 but little above, in fact at high revs indicator goes little over 5, oil pressure is ok.
Usually oil temperature remains from 8 to 9 o’clock, except yesterday whit high outside temperature and few minutes at idle.
As first check I will remove DME and jump the terminals for both low and high speed operation.
Let you know

My oil thermostat insert and oil ballast resistor were bad.
Here's my thread:

Hi all,
Does the door glass from a 993 fit in our cars? Mine is badly scratched from the window scraper rusting out.
I have a lead on some 993 external door handles. Is it a "simple" swap with the original 964 door locks or do I need to have the 993 barrels rekeyed?
Thanks very much,
Neil

Oil cooler fan works both high and low speed.
Relay checked and probably is broken.
I'll check with a new relay hoping it works, otherwise I think to bring two cable into the cabin and turn on the fan with a switch.
