Hello,
I'm slowly going through a '62 Series IIa that was originally a Central American vehicle. Having the cylinder head freshened and a while pressure testing, we found a leak in a large port, approx 1-5/16" in the rear of the head. There was an aluminum threaded plug that was pretty badly corroded and leaking. The threads are badly corroded as well.
(sorry, the photo keeps flipping upside down, I've tried uploading and flipping the image 180 deg and re-uploading)
What purpose does that plug serve? Asking in order to decide whether to chase the threads and find another plug. And I'm curious to know.
Thank you in advance,
Dan.
