I read ALL the Canton pan oil level posts..
I ended to determining the correct oil level using the oil level plug.
...when the oil come out of the hole ...it's the right level
on the pic below...
Which is the oil hole level?
An the others 2 plugs? purpose?
Thanks

My 15-240T only had two holes.

My vote is that the forward facing bung is for the OEM oil level sensor
that later C4's have.

My understanding is that the single top bung on mine is for use with an
optional dipstick - a plug with a metal rod in it in situations where there
is no provision or no room for a dipstick.

Of course it can also be used for a drainback (turbo, ect.)

Is your pan a 15-240T? Any idea when it was built, perhaps the two
bungs on top is a more recent feature or part of a different pan
configuration.

Yes, 15-240T for 1 PC rear seal.
I bought in the 2005.

The way I determined my oil level was to fill the newly installed pan
with oil.

I started by converting volumes because oil is sold by the litre here,
as I suspect it may be there, too.
I filled a new filter and installed it. Next, I added the remainder of the
6.6 litres to the engine. Then after letting the engine stand for awhile
to permit the oil to drain into the sump, I checked the dipstick and
noted where the level displayed. Finally I operated the engine (getting
it up to temperature), let it stand for drainback again and checked
the level once more.

I then felt confident I knew what the oil level should be on MY Canton.

(I later switched to an Armando pan and repeated the process.)

places for oil temp, level etc...
nice Itialian pin-up girls in the back also Beppe! thanks!

Incidently, if you haven't already installed the pan, be aware that
the dipstick tube should be removed from the block for pan installation
and removal.

There is a hole in the windage tray that is mounted to the pan. The
dipstick tube inserts through this hole. If the tube is in place when the
pan is being installed, it is possible the lower end of the tube will miss
the hole and then be bent, lying on top of the tray and giving inaccurate
readings. Once bent, it is not possible to remove the tube from the
block without pulling the oil pan to get access to the bent portion of
the tube crimped/captured inside the crankcase.

If the dipstick tube is not removed before pulling the pan, the end of
the tube will interfere with the windage tray, making pan removal
more difficult and likely damaging the tube and /or the tray.

Yep. I have the same pan on my '94, and the sensor fits perfect right there.

The pas has been installed with the engine out of the car.
So the dipstick tube has been inserted when the pan was in place.
I remember to have enlarged a bit the hole in the windage tray 2 years ago. In any case thanks for the advice.
The problem (the one caused my first question on past#1) is that at my first (and second) oil change i put on the pan 6.6 liters (including filter). Waited the time to allow for oil to go n the pan, I meusure the dipstick and the the level is UNDER the minimum.
I know (reading all the posts related to the Canton 240T) that with 7 qts (6.6 L), the level is usually just a bit over the minimum level.
I tried to reach this level adding more oil. I reached a level of about 3-4 mm over the minimum mark adding an additional liter, ending at more than 8 quarts
(I removed the additional liter later...)
I read that there is a oil plug level on the pan but I'm not sure which is...

The photo of the pan shows an internal hex pipe plug in the rear
location and an external hex pipe plug in the forward location.

.

If these plugs were supplied by Canton, then there is a chance that
the forward external hex plug MAY have a dipstick. A rod may have
threaded or expoxied (temp?) into the hole in the end of the plug.

I took a quick look on Canton's site but did not see a hex plug dipstick.
(More research is required to determine whether they offer them.)

But the OEM dipstick is far easier to use - you've got it, use it.
Three options are to

1. remember where the level is
2. make a new mark with a file
3. change the tube by the distance necessary for the stick to insert down
   further, bringing the indicated oil level up to the OEM markings

FYI I just ordered one of these plugs from Canton.

The forward facing plug (for oil level sensor) is 20 mm. Canton part number is:

22-405

and is called "20mm plug for GM oil level sender port 15-244 F body pans"

Although it also works for us, of course. Tech said to use a little teflon tape and torque to 25 ft*lbs. You also need a crush washer (included).

So to reiterate - we fill until the oil level reaches the bottom of the top facing sensor. If I had an oil level sensor it would be submerged, and would read low when the level dropped below that height, correct?

I had to get one this week.

The dipstick for that location is...

#20-850 or 20-852
I have the 15-240T and the 20-852 was recommended, twice, despite the listing for "15-000 pans" for the 20-850.
