Default Re: 305d V6

Just wanted to update everyone on work completed on the 62 this past weekend. Bore scoped all six cylinders nothing to report there. All looked good no scaring or dimpling in the pistons or cylinder walls. Performed leak down test on 1 and 6. found on each intake valve leaking. backed off on each valve tappet both cylinder at 125psi. Cleaned rocker shafts as suggested, all seems good. Here is the bad. found on the #4 cylinder one of the push rods was damaged/bent. Looks like some one tried to straiten and re-installed. I checked the lifter and no signs of wear. I also got a good look at the cam lobe. Nice and clear as well.. Checked the back lash in the timing chain it too seemed like it has little to no wear.(replaced? maybe) Does anyone have a good supplier for new push rods? The only ones I have located so far are from EGGE and state for 305E.

Thanks again for all of the support.
