Oil Pan baffle question

[Mikeinnj]

I would like to know why the three oil pan baffles shown are different. Can they be used in any Model A oil pan ?

The one on the left had five (5) one inch drain holes plus the oil pump hole.

The one in the center has no holes...... Except the oil pump hole.

The on on the right has four (4) 3/8 inch holes and the oil pump hole.

Thanks, Mike

The only holes would be for the oilpump and the dipstick...Bob F

Someone added the extra holes...does anyone know why?

I thought the idea was some oil remained in the baffle pan depressions so there was oil there even after an oil change........ for the rods to splash the oil all over the cylinder walls and every where else inside the engine block?

Any baffles that I ever had that had been drilled out....I filled or replaced the baffle.

Wrong! The pan with the small holes is for a early 32 B engine, the pan with the large holes is for all fours after probably mid 32 and the plain pan is for Model A.

None of the holes are owner drilled, they are factory and I have a matching set to the ones shown above.

Will take a picture tomorrow.

As they are not in the dipper tray, pos to let oil back into the sump bottom faster, Have drill holes in the dipper tray myself but only when drilling crank for preasure feed on B crank, A G28T has no baffels at all in the sump or splash pan as its called, We always fit two to keep oil near the pump for hard cornering??

As promised. Left to right, Model A standard, Model B late & 33/up , Model B early and, owner modified Model A. Notice the smaller holes in the owner modified and uneven spacing. Also, there are 2 different Model A common trays, one with a long front lip and, one with a short lip. These are interchangeable throughout all years.

Can you tell us what is the purpose of the holes. I have a few model A baffles that have smaller holes that appear to have been made with a punch. I was planning to hammer the punched holes flat and gas welding them up.

The drilled holes are armchair engineering-I would weld them up as original. The ford engineers knew what they were doing in that area and alteration could shorten the life of your engine.

Here is another version with smaller oil valleys this is a very early version.

The tray was lowered (by relocating the ribs on the flanges) and small holes were punched in the flat surface in 1931 to lower oil consumption. A special splash shield was also added around the oil pump at the same time. I can't tell in the first picture if the right hand tray is one of these, but it sure looks like it!

OK, so Doug, that makes the small hole tray a late 31 change instead of 32, right? I can agree with that and the shield. I believe Ford had a problem with oil escaping from the filler pipe from early on with all the changes in the tray and filler tube and these holes were a continuation of that R&D to solve the problem. The later tray had even bigger holes so that must have been the cure because no more changes have been found.

Humm, this is interesting.. Johns pic shows what is in my '31, which has been in it since at least '61.. [The block contains 3 cam bearings,not 5].. At this point, I'm getting concerned..

Correct, the small hole tray is a late 31' change not an early B design as you indicated earlier.

[James Rogers]

Well, I guess a 6 month discrepancy is not too bad. I was just slightly mistaken. I just had never removed one from a late 31 motor.

[Don S]

I have a 5 bearing block that also has a problem with oil loss out the vent tube. Should I be modifying the tray to help prevent the oil loss? Other than the oil loss the engine has no other problems.How about lowering the level in the sump? Right now it is just below the full mark. Thanks

Could someone post a picture of the difference in the flange of the windage/oil tray, from the early one for use without the oil pump shield to the later tray for use with the oil pump sheild?

[James Rogers]

As in the pictures shown, there is no difference in the basic shape of the tray except the front flange or lip is shorter on some. There doesn't seem to be any date for the change as some of the early trays have either as do the later ones and even the late 31's and 32's are similar.

So James, its the second baffle that I should have in my B motor with a counterbalanced crank? Should I be using the slash shield for the oil pump? Thanks for your help!

That's the way they came from the factory. I run the shield in my own B engine.

Good discussion I have two B engines which I had to shorten the B pans to adapt to the Model A fly wheel housing and in the both pans there were no holes of any size both have many miles on them I think I would prefer to keep as much oil in the tray as possible also both have the shield to protect the pump. one engine has 25,000 miles and the other 50,000 still running strong. Maybe Canadian A's did not require holes 8>) Gord. B by the Bay
