Baffle in Oil pan?

[Jgolden]

My oil pan has two drain plugs, one in the bottom of the sump the other in the shallow end. I have always used the one in the sump since I thought it drained the whole thing. Am I correct or am I leaving dirty oil in the pan?

Could it have a solid baffle that requires both drain plugs to be opened?

As usual it's not a Dodge mounted Cummins.

Thanks any info.

Is there a rise in the pan for steering or engine brace? Normally 2 drain plugs indicates there is 2 sumps in the pan configuration.

Do you know your engine serial number? On non-Dodge oil pans their is also a 22mm hole on the side of the pan for the oil pan heater. Shadrach

Cummins has several styles of oil pans.

The marine versions, or at least some of them, have multiple drain plugs.

I had at least 2 on the marine engine in my other boat, and there may have been 3. I chose to use the forward plug as I had a "nose down" installation.

Some installations would have required using the rear plug as they were "nose up" installations.

Either plug drained all the oil ... assuming there was a slight agnle to make the oil gravity drain toward the plug. There were no baffles that held back oil.

My guess it that the industrial oil pans are similar.

Thanks folks.



I'll add the engine number to the post.

I think Jay has the answer. If the engine was higher in the front the plug I mentioned would catch all the oil. It is in pretty tight and I won't mess with it. Good to know there are no baffles. Also There is no way to tell where the pan came from since this rig had a long history that included some front damage.



Jay, As someone who spent a lot of time floating around the world, I have to ask ,with no baffles in the pan what keeps oil available to the oil pump in heavy weather?



Thanks again

Shadrach, here's my engine number 44340786



Thanks

The captain prevents this by staying in port. You think I'm crazy or something?





Seriously there is plenty of oil available. Remember that to start with the marine sump is 16 quarts. And there are specs for how far in each direction the engine can be tilted and still operate. I don't remember what those are though.

OK, just curious, thanks.

I suppose that even applies to a pickup.

I know in a boat if a Cummins is nose up and running fairly hard, it will puke a quart of oil out of the PCV tube pretty quickly. That's because the oil pan stays high and the oil gets splashed into and out of the vent. For this reason the "experts" say run a quart down all the time... . the level will stay there.

This is also true with my current Ford-Lehman. I'll lose a quart in about 10 running hours, then it will stay at that level until I change it at 80 hours or so.

You have a shallow front sump oil pan that holds 11 qts to the full mark ( oil filter capacity not included ). There is NO baffle in the pan. The main plug is 18mm, but it doesn't give a size for the rear one. There must be some oil left in there otherwise why would there be a plug. There are no provisions for an oil pan heater in the side of the pan. It is 160hp and is CPL 804 the same as the 89-91 non-intercooled Dodges, although some parts are obviously different. Eg exh man, oil pan, flywheel housing to name a few. See if this will open for you. It is option OP9030 for those who can access Cummins Quickserve. Shadrach

In case you are interested your motor home engine "tilting limits" are
front up 22*
front down 12*
side to side 20*

Thank you ,Sir. Good info.

PS I'll have to stay land based.

Jay, even on the straight and level my Cummins will blow through a quart pretty quickly (I had to extend the tube) and then use almost none. I have gone to the qt low on oil change. I'd also like to find a way to vent a valve cover or the fill hole if it was possible to direct the vented oil down and away.

Thanks for the info.

There is a way to vent the oil fill tube. It is a somewhat common modification done to marine engines. There is a small filter that looks like a K&N that clamps on the tube and the "fumes" are vented to the intake filter neck.

Thats interesting I have been leaving my dipstick pulled out a little and it has eliminated most of the oil seeps around the pan etc.

Having a filter would be much better.



PS Why do I think Pete will have a comment?

Why do I think Pete will have a comment?

Because he is one sick son-of-a-seagoin'- sailor:-laf

(as I am)



I can't post pics for some reason (stupidity perhaps) and I have asked Scott to post them for me. So hopefully the vent pics will be in this thread eventually.

Pete has been one sick sailor. Been down with pnuemonia for a week now. Just starting to get better.



Dipstick pulled out?

 

[JLEONARD]

Glad you feel better Pete..... I was getting worried... this post was "out there" a long time... .

 

[Jgolden]

Pete,

Been on the road for a while, glad your feeling better. Probably too much time in the cold with your dip stick out. Spring might come, even to Syracuse.
