I'm rebuilding my first engine. It's a 1981 300td (617.952)
One of my pistons was bad and I bought a used one from a member. Got it all put in the block but then realized that it is a different group number than my other pistons. I guess that means it is a little larger. Does anyone know if this is a huge problem? Do I need to take it back out and get a different one? My crankshaft seems to turn fine. All of my pistons are group number 1 except this one that is a #2.
Thanks for any help.
