I have got for sure a couple of freeze plugs that are very questionable. One of them is behind the 383 starter and maybe one over on the passenger side,but not all are bad. I guess my question is: Is it possible to pull out the bad ones while the motor is in? Just can’t see any time in the near future where an engine pull is possible to really do it right. Don’t want to just let it sit,that would probably be worse!
