Re: Wishbone alignment
Ross/Kzoo
The only book that I had growing up as a teenager, and working on my Dad's '31 CC Pickup, in the '70s was: Model A Ford: Construction, Operation, Repair for the Restorer written by Victor W. Page Therefore, I believe that I read about the basic procedure in his book. It described using Fine Threaded Brass Rod. I went to the hardware store and couldn't find brass rod in fine thread, but I found 1/8" Solid Brass Pipe Plugs. I thought that this would work better anyway because of the fine thread and the taper of the plug. I started by drill stopping each end of the crack. I then drilled and tapped the first hole on either end of the crack, I ground down the end of the tap so that I wouldn't run into anything in the water jacket and I could obtain just the right depth and tightness (not to tight, not to loose) on the Brass Plug. I then ground each plug near flush with the block, I drilled half into the first plug/half into the crack, drilled, tapped, plugged, ground and worked from both sides towards the middle. It almost looks like solid brass when finished. I center punched each plug to expand/set them firmly, ground down the plugs about flush with the block. I then painted the block with a polyurethane paint that I mixed up. I had overheated this engine about 25 years later and blew a head gasket when I first put it in my Phaeton and it had developed a slight tick that only I seemed to be able to hear. When I took it out I found a scored piston, I filed down the score marks, honed and deglazed the cylinder, re-ringed it .020, the rods had been eaten away from the Antifreeze during overheating, STD Size, I bought a set off Ebay for $101.00 installed them and it runs extremely well and I have put many thousands of miles on this engine. I wanted to show the repair to a friend, who actually thought I was crazy when he saw me do this originally, because he had bought a quite expensive H and H engine that had a rusted out/poor casting at the rear water jacket about where the throttle linkage mounts. Thankfully we ran his engine on a test stand and found the leak before he installed it in his car. We repaired it with a half dozen pipe plugs using the same procedure. It is a Diamond B engine I took out of a '32 BB, put it in a '31 CCPU I built from parts, later installed it in my '31 AA, then into my Dad's '31 PU, and it currently resides in my '30 Phaeton. Hope this helps, Darryl in Fairbanks |

Re: Wishbone alignment
Thanks Darryl, I'll put that in my memory file and hopefully I won't need it but it might help someone else.

Re: Wishbone alignment
Wow thats great. I would have tried that method over JB Weld, but other concerns ruled out a fix. So I'm thinking you are drilling one hole, threading it, then tapping in the rod and then move over and drill the next hole into the block and the previous rod. That's slick
