Just started an overhaul of a D14 that came with some property i purchased. So far, no surprises, but one did surface last night. For those familiar with the 4-cylinder D14, it uses a combo intake/exhaust manifold. On mine, it is a complete rust heap and worthy of replacement. I figured the manifold studs would be a challenge, and over the years i've developed easy-to-more aggressive methods to get them out (or in this case leave them in if the threads looked good). After removing the muffler, i started to examine the manifold.Sometime in the past 60 years, looks like someone else tried to take out the studs. The stud on the far outside left threads in to a sorta "socket" that sticks off the block. If i had to guess, someone probably put way to much torque on the bolt, and it cracked off part of the female socket so that i could see about 1/3 of the treads of the bolt in the female socket. That stud was easy to remove, but now i'm trying to weigh repair options. Ponder: 1/what is the block material on a d-14. If it's cast iron, which i suspect, harder to weld a patch over the broken off female threads. 2/the male bolt
is grabbing about 2/3's of the thread channel , and it will take some torque. This is really an engineer equation, but for us garage guys, i think i'm going to use thread locker (red), reassemble, torque all to around 30 ft/lbs, and see what
happens. At this point i figure i have nothing to loose, and if this fails, depending on block composition, weld filler on the female socket , or if cast iron, take to someone who is good at that. Any other ideas? Toolman
