My Ford OM says remove any engine oil overfill immediately or it will cause engine damage.

On what engine, a 1949 merc? Cant generalise here - some engines are tolerant to overfill - some are not.

Tell me which automotive engine is sensitive to a 1/2 quart overfill; I'd be interested in knowing that.

My '00 MB E430 is very sensitive to overfill, the on-board computer/oi monitor flashed a warning when I had 6-8oz overfilled. After I removed that amount with a fluid extractor, it was happy to report "Oil Level Okay"

Thank you, I'll file that away under useful information.

That's pretty cool! If I owned a car that did that I would find out at what point it triggers that warning, then take out one ounce of oil
I like overfilling my engines, once I determine the safe point. I've been adding one extra quart to my Corvette ever since I got it (although my owner's manual does say it's safe to add that extra quart when racing)

I was changing the oil in my brother in laws santa fe a few years ago. He said it hadn't been done in a while but wasn't sure how long. The first thing I noticed was the sludge under the oil cap. I expected it to be very low on oil, and to only drain out a couple of litres. Well to my shock my drain pan almost overflowed and it holds 9 litres. It turns out that he was checking his oil every time he bought gas and due to it not sitting long enough for the oil to drain back in the pan, he thought it was low. He was topping it up about half a litre every time. After the oil change his oil was reading about a litre low after letting it sit 20 minutes. His oil passages were so sludged up I had to let it sit overnight to get an accurate reading.He probably drove it that way for 6 months or more without a problem.
I'd take it back to pep boys and have them fix the problem.
If you are "scared" - you should be able to empty the oil filter into a proper container (may as well save it for your next oil needs, as it is basically fresh oil......) re-mount the filter, and crank the engine up......the oil from the engine should now move into the filter, taking the dipstick level down
Little less "messy" than messing with the drain plug
I suppose, if you wanted, the other option would be to "siphon" some of the oil out of the engine through the dipstick tube; either using a cheap sipon, or a more expensive Blackstone, or Amsoil Oil extractor pump....comes in handy months down the road for mid-OCI used oil analysis anyways.

2005 Suzuki (Aerio) 2.3L DOHC - It would pump oil right into the PCV and swamp the intake if you overfilled it and cornered with moderately high G's. Aks me how I know

If you get a warning from the info system you should drain the overfill as ASAP.
The problem is that oil can be sucked into the catalytic converter and destroy it and other emissions components like the O2 sensor and PCV valve ect.
Generally a 1/2 qt over is no problem but if you go significantly over a qt you need to get that excess out.

Overfilling oil is not recommended by any manufacturer. I used to do it don't bother unless the sump is designed for it.
The extra oil volume increases the warm up time required to get the engine oil to operating temperature.
I run the oil down to a 1/2 full on the engine oil dip stick and top up to the full mark as required.
If you are that worried about it just change the filter that will get 0.5L out. It will cost you a filter plus oil so what.

What a pain in the a$$. Pep Boys doesn't want their filter to fall off so they probably overtightened it.

forgot to update -_-
I did loose the drain plug and til it have small stream of oil coming down, I put empty quart under it, 30 min later it fill up half quart, then I let it drain out a little more, to add MMO.
btw I take off that pepboy oil filter and replace it with motorcraft oil filter ( pepboy oil filter look like well made )

actually pepboi over fill almost a quart.

With almost a quart over you did the right thing.

It still above the mark just a tiny bit, not to worried about, not like before. Tomorrow I take a pix of the quart I drain out and post it here, for the heck of being BITOG lol

Here the pix
, still over fill above the fill mark just a little bit.
for some of you, over fill this much is normal ?

I would have left it. 700 ml over the area of the sump is what, a cm or so? Zero chance of the crank ever hitting the oil.

I guest it wont hurt, but it made me sleep well at night
