360 Oil reservoir issue/F1 transmission issue

I am having a few new problems that I can not figure out. I recently got the car back from an independent shop. It was sent there because of a heat exchanger failure which was caught early. Keep an eye on your coolant color in the reservoir people! Anyway, I am now having a different issue. While it was there I got the shop to do a lot of other things that needed to be addressed. One of them was the oil reservoir paint was chipping away so I had them repaint it. After I got the car back I was doing my regular checks and I noticed that with the car running and up to operating temperature the oil level is showing way too high. The Technitian assured me that there was no more than 10 litres in the system and it was completely empty when he added the oil to the system. I also am not getting smoke indicating the car is over filled so I believe him without a doubt. However, this will make it impossible to check my oil or do an oil change and be able to accurately fill it to the correct level. Has anyone ever seen this before and can the seal on the reservoir go bad and give a false reading?

Second issue. The car will shudder and make noises from the gearbox at low RPM and low speed as if you had a manual car and you tried going slow through your neighborhood at 10 MPH in 5th gear and at highway speeds and low RPM with very minimal throttle input it will slip out of gear and the gear indicator will flash till I select neutral and re select a gear. I have no issues with moderate or heavy throttle input in mid to higher RPM’s. The clutch was measured and it has 90 percent life REMAINING. The clutch was done a few years ago. I am thinking either the PIS is off or the 21 year old accumulator is gone. I heard the accumulator life span is only about ten years anyway. Anyone have any insight? Thanks in advance.

The pump primes for about 11-15 seconds when the door is opened. It is a little longer than when I got the car which was around 8-10 seconds. The accumulator is 21 years old though so I’m hoping that is the issue or it is at least something easily remedied. As far as the oil, yes. They are easily overfilled. What makes me believe that something else is going on is the fact that there is no more than 10 quarts in the car. The car holds a total of 12 quarts if I’m not mistaken and the dipstick is registering all the way to almost the top of the dipstick which would take most likely an overfill of 5 or 6 quarts. It has been suggested that the seals inside of the oil reservoir may have failed causing this or thy the little mesh filter in the transmission has a part that may have gotten stuck causing this reading. Has anyone heard of this before? Here is the picture of the dipstick. The first red lines are where the low and high measurement marks are and the third is where the oil is measuring.

It is a dry sump. The oil was checked with it at full operating temperature with the engine running with the cap resting on the filler neck. I have done multiple oil changes on this car however this is the first time it is reading incorrectly. This is also the first oil change done by someone else after a major repair and he states that he only ordered 10 quarts of oil and filled it on a completely empty system. The reason I believe something may be wrong with the oil reservoir is because it was removed to get repainted. I’ve just never heard of any issues with seals in a reservoir so I wanted to see if anyone’s ever heard of such a thing.

I agree with you. I’ve decided to do that, I just wanted to be sure there wasn’t a seal or sensor of some type that is giving me a false reading. I’d hate to not have enough oil in the system due to not getting an accurate reading.

I’ll keep you posted. I think I’m going to drain it and start over. It’s just hard to believe that a very skilled technician would over fill it this much, since the reservoir was removed I thought it was possible something had failed.

Ok, so I got the car up to full operating temperature and I decided to use my fluid evacuator first to see if that would work before draining all of the oil again and spending even more money. Well, I’m happy to report that I believe this worked. I got it down to the correct level while the car was running and at operating temperature.... just in case anyone was going to ask. I will check it again in a few days by getting it up to temperature to be sure the oil level remains the same. I am confident that it will be. I extracted a little more than a quart from the reservoir. Im so glad it wasn’t sucked into the intake manifold and I didn’t get smoke or that mess in the heads.

Haha. I’ve never found it difficult to get the oil level to the correct measurement but a lot of people seem to make this mistake. On my records a Ferrari dealership over filled it on the first oil change. lol!

That was my thought. I was thinking that we all care about our cars and take our time more than a technician who is doing 10 in a row

Honestly he owns a 360 and is a Ferrari specialist so I do think he may have just not had enough time to get it as warm as it should have been even though he states it got up to 70°C typically I fill mine at 90°C which may make a difference

Nope. Always while running
