what to do with this hole in eng block
So I have a 400 motor that I just rebuilt. And I noticed this hole after it came back from getting vatted out.
I forgot about it until after I put it all back together.
I believe its for a oil dipstick. But I have one that comes out of the pan.
So How do I seal this off so I dont have leak?

If I recall correctly it is a 0.375 hole and a soft metal (brass) or deep 3/8" freeze plug will block it off.

This plug has been on other posts on this site before. Some members had the right dimensions if you wanted to buy from a chain store and I believe Number Dummy may have also provided the Ford part number if you wanted to buy it from Ford.

That is the hole for the front dipstick when a front sump oil pan is used. From the factory, the hole was plugged with a small cup plug (frost plug) when a rear sump oil pan was used (4WD truck applications). A cup plug is the right fix, should be cheap & easy to find.

I thought about dropping a short bolt with a bigger head and silicone it.
