  • Engine: Push rod length

    Well,I found a bent pushrod in a 64 lark type 289 Canadian built, so pulled one out of my spare 289 and it is shorter, even tho one is bent it is still longer than the good one, how many lengths are there to deal with?

    There are three lengths: two for the V-8 engines (early and late) and one for the OHV six.

        The short ones are in my 59 Hawk and the long ones are the 64 289,so I better not mix them.

            Seeing this a couple of weeks old, I thought I might bump it up. I also have the longer push rods from a 62 or 63 289. Checking for bent rods, I found nothing looking like a tree branch. Good thing there. But, when I roll them on a pane of glass, I found about half of the rods have a very slight bend at one end, the rocker arm end. This very slight bend starts about 1 inch to 1 1/2 inches in from the end. The gap is tiny, but there is a gap. The rest of the rod rolls true to the glass.
            wondering if there’s anything here. A couple friends have never seen this. Wondering if anyone on the site has noticed this.

              OK, Half of the Rods have been over stressed. Time for a new Set.
              A GAP? So they ARE Cracked?

                No cracks visible to the eye. Maybe under a microscope. I was thinking the same thing, Rich. Lord knows how millions, maybe billions, of times those rods had pushed up the rockers, so maybe just a stress issue. I had not seen or heard of it before. A new set is on the way from Uncle Phil. (He hadn’t heard of it either).
