My 6.9 had a different size oil pan drain plug than my 7.3 does
I have a 1990 engine in Duchess, my 86, and for my understanding, they did make some changes to the 7.3s for the model year 1990. The 6.9 that was in this truck originally was of course an 86, and it had a larger drain plug. The one on my 7.3 is pretty small.Both of the 6.9s I had (85, 87) used 1/2-20 same as this 89 7.3. Maybe very early ones had something else?
I know that there was a difference in the size of the hex parts. One size was 7/8" while the other one was 3/4". Is that what you're talking about?My 6.9 had a different size oil pan drain plug than my 7.3 does
No the actual threads are different. As well as drain location. Will show in the morningI know that there was a difference in the size of the hex parts. One size was 7/8" while the other one was 3/4". Is that what you're talking about?
