freeze plug size??? where to get

[mtm93ramnasty]

ive been goin nuts tryn to get the right size freeze plug i measured it and it seemd to be 2 5/16, but i went to the parts store they said its 2 1/4. i put the 2 1/4in and seald it...i startd it up no leak untill i floord it, the damn thing blew right out. also wheres the best place to go to get one ive been to napa, a local auto parts stoor, sg diesel, and my brother works at a mechanics shop and couldnt get one. would advanced auto have the right one? what about a cap for the end of a pipe if i could get the right size

Have a local machine shop make you a set of these...




Or you can buy them from Pure Diesel Power for $40.00 each.

Old block heaters work great as well.

Most of the plugs on our engines are 58 mm. Can't get them at NAPA or the crappy auto parts stores. Cummins or a Case/IH dealer.

lol my next stop was gonna be a trackr dealer but thanks for the block heater idea just hapns that i have a spare cummins took the heater out and shes running good! im leavn early tomorow morning to get it on the dyno i dont think its gonna make that much power it runin out of fuel but it will hit 49lb of boost so well see what hapns hopefully ill be close to 400 but im thinkn more like 350
