Engine: StudeRich; isin this the 'plug' in Distrubtor cavity you were talking about?

Hi StudeRich, (and anyone else reading this :-)
In a recent reply to one of my posts, you cautioned me to be SURE that my machinist replaced the pipe-plug INSIDE the distributor cavity, reached from the back side of the block before he put in the rear frost-plug.
I think this must be it, couldn't find any thing else, but is a 3/8-18, not a 1/4" like you said, so thought I'd check to make sure I'm not missing a 'hard to see" hole somewhere and regret it later!
The one I'm thinking you meant is the one right in the center of the photo, down inside the block obviously....
Better safe than sorry.
Thanks for pointing this out!

It is a 1/4" NPT pipe plug which measures about 3/8"

If your fingers are long and thin, it can be installed without removing the freeze plug. No kidding! I'm actually serious!

Yep, that's it...and as Brad (rockne10) says, if you have long, thin fingers, it can be installed from above, although it is difficult.

It is best installed from the rear of the block before the appropriate core plug is installed after thorough block and passage cleaning. BP

Thanks; good to have confirmation. Sure didn't see any other place he could have been referencing.
I wish I COULD do my own cleaning of it, the guy put in frost plugs (and all these pipe-thread plugs with silicone sealant,, etc... when he bored cylinders and seated valves; bummer, I had already bought the 'small parts kit' with all those plugs AND wanted to run a gun-wirebrush cleaner through myself... He thought he was doing me a favor. :-)

However, he builds race cars and talked about cooking and twice my block twice because it was so dirty (he was really interested in the Stude engine, "don't see many of those!".... nice guy.... sounded like someone very methodical and careful). Knew to cut down (or use?) thinner exhaust seats, to prevent cutting too deep, etc... Put special oil-seals on valves (little blue things with ring-springs), had to machine the new guides for them, but supposed to REALLY prevent any oil seepage through the valve-guides...
SO, hoping he was also thorough in his cleaning..... and he got everything clean in there. From what I can SEE, it is, and when I forced water through after soaping it up, got NO 'residue' or crud of any kind, just had to clean it because I'd wire-brushed it, etc.... piror to painting (before it gets too cold here to do so in my shop!!!
THanks again!

Now the Rocker assembly is MY job to take apart and clean, and I have my 30/30 gun cleaning kit out there already for that job. :-)
So while I'd like to have seen the inside of the block (through the cavities now blocked off) myself, I think this guy got them pretty clean.

[StudeRich]

Yes that IS the Only Plug in that area, you got it, Good Job.

Just change the Oil after 500 Miles, it will be fine.
