overfilled the DODGE 2003 GRAND CARAVAN during oil change

Hello all,

I think by mistake I have overfilled my DODGE 2003 GRAND CARAVAN SE
with 1 to 1.5 quarts of oil.. It is like 1 inch over the max level on
the gauge.

I have not driven the van too much around. Should I try to remove 1
quart? or is it fine to wait for the next oil change..

please let me know your thoughts..

please see this article below.

CAUTION: Do not overfill the engine. Adding too much oil can overfill
the crankcase. As the crankshaft spins around, it can whip the oil into
foam if the level is too high. This, in turn, can cause a drop in oil
pressure and loss of lubrication to critical engine parts. Also, too
much oil may cause leaks as the extra oil is forced past seals and
gaskets.

 

I'd go ahead and remove a quart. Having the level too high puts it in
greater contact with the spinning crankshaft and it get splattered around a
lot more inside the engine. It might be fine, but there are some problems
that can result from that.

 

To much can be as bad as not as not enough. :lol2:
Better to be safe and get it back to the full mark.
Your engine will love you for taking care of it.

 

The main problem it will turn the oil into foam and stop lubricating the
engine. Drain the extra oil out.....

 

Or possibly create Hydraulic Lock if the oil pressures itself past the
seals...

 

If you replaced the filter, but have not started the engine yet, you may be
seeing the filter volume (which will go away when you start the engine).

Otherwise, if you have really overfilled it, then drain out a quart or so.

You can tolerate a little overfill with no problem, but a quart or more is
too
much.

 

????????

Would you please explain the technology supporting this statement?

 

Are you sure you put in too much oil? I had a Dakota that took 6 qts in
the 4.7 V-8. I was the first person to change the oil and the dip stick
showed that it was over full. I was positive I only put in 6 qts. with
the filter. I found out the Dakota had the wrong dip stick. I never
found the correct dip stick, so I just filed a notch where the FULL
level was.

Oil is under pressure. If there is too much oil, and the pressure builds,
then it can push out seals meant to keep it out of places. If the OP is
luck, it will push a seal out at one end of the engine or another and leak
onto the ground or into the tranny (depending on your definition of "luck")

If not, it can push out the valve seals and drop into the engine, and
since a liquid cannot be pressurized...BANG! Hydraulic Lock...

 

Er....

......exactly what engine are you talking about that has pressurized oil
against the valve seals?

Any oil that manages to bypass the valve seals usually ends up burned -
creating that familiar blue smoke.

 

There is nothing accurate in this post... The oil pump is sucking oil
out of the oil pan which is essentially a bucket. The oil pump has no
idea if there is 1 quart of oil in that bucket or 300 gallons of oil
in that bucket. The problem with overfilling is that the spinning
crankshaft comes in contact with the oil. The whipping action of the
crankshaft will aerate the oil and turn it in to a foamy froth. The
oil pump can not pump this froth so you loose oil pressure and soon
after loose an engine if you don't stop.

Valve seals are not exposed to pressurized oil. Any lubrication needs
they have are handled by oil splashing off the other valve train
components.

You are correct Steve. Also, don't the oil pump have a pressure relief
valve built into them so that excess pressure doesn't build up?

Oil is under pressure. If there is too much oil, and the pressure builds,

Oh wow that's quite the story. Liquids can't be compressed eh? Well damn,
that's just re-writing the laws of physics right there. I guess oil doesn't
burn in the combustion chamber either. You learn something new every day.

 

While he's wrong about the oil "locking up" the engine, it is indeed true
that liquids can't be compressed. You can put pressure on a liquid, but
you can't compress it. There's a difference. That's the fundamental
principle of how hydraulic systems work...

Perhaps you should have paid more attention in that high school physics
class...

 

As wrong as he is about everything else, Pascal's Law - and virtually
everything hydraulic - works on the very principal that liquids, in fact,
CANNOT be compressed.

They can be pressurized, but NOT compressed.

OTOH - You are correct in chiding him about oil burning off in the
combustion process.

 

'88 Honda Accord. JiffyLube overfilled it by three quarts. I don't know
how it happened, I know they gave me a new engine...I'm just going by what
the Honda Service Manager told me. I figured he knows what he's talking
about...

 

The oil sitting in the pan is not under pressure (under normal conditions
in most engines, I am sure if I didn't write this someone would find a
some engine made in east germany in 1961 that was in 45 cars that had the
oil in the pan pressurized and call me a dumbass for not considering it).
The oil in the passages is. The pump picks up the oil and it is pumped
through the system then returns to the pan. The oil pressure builds
against the resistance of pushing the oil through the small passages,
bearings, etc.

When an engine is over filled with oil, the oil pressure doesn't
increase, the crank dips into the oil in the pan splashing it around. The
oil get frothy with air and then these air bubbles are in the oil as the
pump picks it up and circulates it. Of course air doesn't do a good job
lubricating internal engine parts and the engine fails.

 

Your Honda "Service Mangler" is either full of it, or he doesn't know what
he's talking about.

Either way, I would find another place to have my car serviced and
repaired.

 

With a 3-quart overfill, I can picture some damage being done, including
blown seals (penguin/ice cream jokes notwithstanding).
