When I pulled my F engine apart, all the oil ports on the connecting rods were facing in the same direction the difference being the lock bolt for the piston pins were facing in different directions. Which way is correct? Also all the vertical slits in the pistons were all in the same direction. (to the right looking at the front of the engine). Is that correct? Thank You.

Willys Jeep Parts Tech:
Email mike@kaiserwillys.com and i can help with. I'll scan in some pages out of book too to help as well and email them to you.

How can you tell which rods are 1 and 3 or 2 and 4 on a set of original rods?

Willys Jeep Parts Tech:
The easiest way to tell is by looking at the position of the oil port plug. They are in the opposite positions for the 1,3 then the 2,4. Thanks

What is the length of a 134 4cyl Jeep connecting rod?

Willys Jeep Parts Tech:
11-3/8" overall approx.

Do I need to replace all four for a rebuild or can I just replace the ones that are bad?

Willys Tech:
I always recomment relacing them in sets for balance.
