Oil Pan |

| Do BOSS 302 Oil Pans have you baffled? Not sure which is the right one for your car? You've been searching for the correct part but nothing has panned out? |
| Just like there were two model
years of BOSS 302 cars there were two versions of BOSS 302 oil pans, 1969 and 1970. The 1969 oil pan assembly (When you take an oil pan and add things like a baffle and drain plug it becomes known as an oil pan assembly in Ford lingo.) received engineering part number C9ZE-6675-H. In the partial print shown below you can see it starts out with a basic 289 oil pan with part number C5AE-6676-D and then the baffle, C9ZE-6687-D, is welded in later. |

| Note the flat bottom as shown in this picture. |  |
| Thus, the correct oil pan assembly for the 1969 BOSS 302 has a flat bottom, baffle inside and should be stamped with "C5AE-6676-D" and a date code. The original service part number would be C9ZZ-6675-? Sorry, don't know the suffix. When you think about it, the 1969 BOSS 302 oil pan might be hard to find given the low volume of 1969 BOSS 302 cars and the fact that this part was replaced for 1970 and superceded for service by the 1970 service part, D0ZZ-6675-A. It is possible though that the C5AE oil pan stamping was continued for service for many years and with the addition of a baffle was shipped as D0ZZ-6675-A so these pans might not be rare at all. |
| Things changed for 1970. The 1970 oil pan assembly received engineering part number D0ZE-6675-A. Like the 1969 oil pan assembly, it started life as something else. D0OE-6675-C can be seen below in the lower right as the main part number in this drawing title block while D0ZE-6675-A shows in the notes in the left column. |
|
|
| Here's the note specifying the addition of the baffle which made the D0OE-6675-C become D0ZE-6675-A. |  |
| Note the strange looking curves near the rear of the 1970 oil pan. |  |
| The strange curves turn out to be indentations as can be seen in the outside photo at right and the inside photo below. |  |
 |
 |
| The 1970 oil pan was also stamped with a part number and date code like the 1969. |
 |
| Thus, the correct oil pan assembly for the 1970 BOSS 302 has a contoured/indented bottom, baffle inside and should be stamped with "D0OE-6675-C" and a date code. Service part number is D0ZZ-6675-A. |
| We have shown photos of two parts and members report seeing oil pans without part number or date code stampings even though the requirement for each is clearly stated on the drawings. Do the original pans have the stampings and service parts do not or vice versa? |
| Member 'Hawkrod' says, "First off let me say that over the counter pans DO have stamping dates and date codes despite what one member has heard. The issue here is the BOSS 302 pan and how it was used and marketed. The part was actually a very popular aftermarket item and Ford sold them for many years after the BOSS was long gone. They were never used on any other application from the factory (that I have ever found but I don't know if it was used for marine applications) but how they were made and the length of time they were offered is why you see such a variety of versions. The reason there is such a variation in styles and numbers is because Ford made BOSS 302 pans from standard 289/302 pans. They took a standard pan and welded in a baffle and it became a BOSS 302 pan. The standard pan underwent revisions from time to time and, whenever a change was made, the pan got them." |
| It's possible that Ford removed the requirement for the stampings. It's also possible that when the part number stamping punches wore out they were removed and never replaced by the vendor(s). Don't get caught crawling under cars at car shows looking for the part numbers in BOSS 302 oil pans! |
