Re: The Flathead oil modification thread...
Here's where I drilled through the lower vertical oil passage, and how I fixed it.
Passage was enlarged to 9/16 per mod specs. I found that 3/8" copper pipe sweat couplers are a snug fit, so I tapped a pair in there. The blue you see is Loctite.
I also reached in there and flaired out the edge a bit to insure they won't crawl up any.
After block is cleaned out, area will get a nice coat of J-B Weld. Should be good then.
