    Hi everyone. Got a 50 olds 88 with the 303ci. Drivers side front freeze plug went out yesterday. Looks like a super tight spot to get to, and pulling the motor sadly isn’t an option (tiny one car garage in an HOA controlled town house) has anyone managed to get freeze plugs in on this car WITHOUT pulling the motor? Thank you everyone!

    They make a rubber plug that has a stud coming out of it in many sizes, just tighten the nut and the plug expands to seal,I think they call them boiler plugs. I have used them many times with no problems

    they are called rubber expansion plugs, they make many different kinds and sizes your just going to have to look for the right one and size.

    Thank you so much! Went to Advanced auto, picked my size up and was able to enjoy my olds again! Much appreciated
