Are there any tricks to installing concave freeze plugs in 235/261 engine blocks. The plug I need to install is located behind the bell housing, so a leak would be very unhandy if discovered after the engine is installed. I looked in the GM factory manual and did not see this topic addressed.
Thanks for the help, Bill.

If so, put some sealant on it and hit the centre to expand it. A rebuilder told me to place a hammer on the centre and then strike the hammer with another hammer. I have some photos in my webshots of mine before and after. http://rides.webshots.com/photo/1316417356041873203xTDshC I replaced mine when I had the toeboard cut out. | | |
