I've broken the outer most bolt for an EA82 oil pump. This is the bolt closest to the ear of the mickey mouse seal. Whats the likelihood of an oil leak if I finish the re-seal and t-belts? The other 4 bolts are fine and torqued down. I've tried drilling the bolt out because it broke flush to the engine, but I've caught it out of center and I'm losing hope that I'll be able to drill it clean and tap a new thread. If you guys recommend fixing the hole and re-tapping it what kind of drill bits would you recommend? I was doing this job in hopes of ridding the engine of the lifter tick, but I'm worried I've just made the problem worse. Any and all advice appreciated, thanks.

After reading all the threads throughout the years, I never broke one of these bolts...until today. One bolt was stuck, used a heap of penetrant and heat to try and get it out, buuuuuut... It's the one on the left. Got the other five out, however now I can't slip the manifold over the broken bolt. What are my options? -
My former White Wagon, the Weberized EA82, (now my "BumbleBeast") Was Leakin' Oil, but the Surprise is that it Wasn't from the Usual Places... it Was comin' from the Base of the Pipe Used to Pour Fresh Oil on the Engine, the one that Goes to one Head ... One of the Threads was Damaged, I don't know How ... Maybe it was Loose and Vibrations did damage it. How to Easy Fix a Damaged Thread on Aluminum in a Engine's Head? Well... I Started Removin' the Pipe. Here you can see the Oil and dirt that came from its Base And to Prevent Small Metallic debris from goin' inside the Head, I placed a Small Cloth very tight inside the Head's opening, and Covered it with many Masking Tape Layers. Then, I Drilled the Thread! ... ... Yes, I Drilled it! Originally it Was Like 1/4" ... I Drilled it to 3/8" Here you can See a Closer Perspective: Then, I Remake the Thread, but in 3/8" ... See: Here comes the Solution: I Drilled inside a 3/8" Bolt... ...And I made the Original 1/4" Thread inside the 3/8" Bolt! (Important Note: Don't Forget that Stock are Milimetric Measurements, I wrote Here the Equivalence on inches for easy Reference) Then, I Just Used Thread Locker, to Screw the 3/8" Bolt on the New 3/8" Thread on the Head, then I Removed the 3/8" Bolt's Head. (it was Pre-Cutted in each side, to make Easier Removal of the Head) Finally it Looks like this: And it Solved the Problem, Absolutely!
