Dealer ovefilled oil slightly

My dealer just did an oil change (MY 99 C2) and added a smudge too much oil. Is 3-5mm over the full mark on the dipstick a problem? I did a search and it seems like I should be OK, there are some threads where people who track their cars overfill to combat wet sump starvation. Or should I remove the little excess to be safe. TIA

Very easy fix. Just remove the plastic housing cover for your oil filter cartrdige and you will be able to discard the oil that has collected into the housing. Do this as many times as is needed to get the oil level back to normal.

Any pics of where the cartridge is located? Is it underneath the car on the rear passenger side? Do I need any special tools? TIA

You will need either the oil filter cartridge removal tool or very strong grippy hands The cartridge is a black casing going vertical just inside the wheel housing on the pax side rear. I could take a quick snapshot for you if you like.

Thanks Dell I've located the cartridge, but I think I will need a proper tool as its hard to get any leverage, my car has JRZ coilovers and is very low. Thanks again

tell the dealer to take care of it then.

No problem. The removal tool is a standard european removal tool. Works on ALL of my P-Cars as well as my MB. Of course you can also get one at the dealer. Here's a picture of what it looks like. Has something like 14 slats on the inside.

If some of the track rats are slightly overfilling and pushing their cars hard , should I be ok in regular street use until the excess burns off? Thoughts?

You should be fine. As for the overfilling for us track rats, I have never heard of that. Personally I would remove the excess. Not good to have an overfilled system.

If there is way too much oil it can get sucked into the intake. You will know this right away because of the smoke clouds behind you. A small overfill that you have is nothing to worry about.

Next up, you might start complaining about the notorious white smoke on hard acceleration and occasional morning startups...

Update.......... I took her for a good run this morning and checked the oil again and its perfect now! Right now its at the the top arrow. Thanks to everyone

Did you do anything at all? Or did you just took it for a run and checked it? If that's all you did, you do know that for an accurate reading, you have to wait for a while after turning off the engine, before checking the oil level...

Cosmos is spot on. If you just go for a spin, then check, youwill have a lower level since youhave not allowed the oil to drain completely into the sump.

I let her sit for 15 minutes before checking.

That'll do it. 15 isn't even close. You want a "perfect" reading? Wait and check first thing in the morning before you start her up.

I will check it in the morning again. Thanks

Welcome

I recently picked up my car from the dealer to fix a leak coming from the valve cover gasket(I believe) and they overfilled my oil level. So I took Dell's advice and removed the oil filter cap and dumped that. I also had to buy the oil filter wrench and the photo helped me find the correct one. Thanks Dell and Rennlist for the help.

Regarding the oil filter wrench, you can by one like in the photo dell posted, or you can pick up a cheaper version (i.e., lower quality) for a couple bucks at your local autozone/checker. If I recall correctly, there were 3 or 4 different sizes that looked they could work, and I bought them all to see which one fit, and returned the others. When I get home tonight I'll check the size and report back. You have to be careful about getting the right size becuase some of the wrenches are very close, but not perfect, and can thus slip and potentially round off or otherwise damage the ribs on the filter cartridge.

I use a FloTool SuperGraphite oil filter socket wrench on all of my cars. I have 3 or 4 of them for the different sizes of filters. The wrench is made out of exactly the same stuff as the Porsche oil filter canister is made of. The correct one for the 996/986/997/987 is the #7 and is about $4 at any auto parts store. It is 74mm with 14 flutes. I have been using these wrenches for years with no problems. Also let me comment that the best time to get the most accurate oil level reading is after the car has set overnight.

It's a non-issue, really. It'll just burn off, no need to fret over it.

Another easy fix: drive it hard for a while. Excess oil will spill over and burn off. Happens to me at the track all the time. -td

Actually it is. Easier than taking 5 minutes to remove the oil filter cover and dump out the oil collected in it? Or a bit longer than 5 minutes to do it a few times over driving it overfilled and risk potential damage? It's NOT good to run that car with it overfilled. Burning it off is the best way to do it if you don't like to take care of your car properly
