I've searched and have not seen this one.

Recently rebuilt motor with new freeze plugs and both plugs on the backside of the heads are corroded and leaking

Any easy way to replace them?

I am afraid you will need to pull the engine, at least enough to have room. Steel plugs are the worst / cheepest. Brass plugs are second best and stainless are the best. JMO

There's nothing wrong with steel freeze plugs. If yours are corroding (no matter how old they are, but especially if they're new), it indicates serious problems with your coolant. Either you're buying crap coolant, or you're not changing it on-schedule, or you have something causing it to become corrosive (head gasket leak?). Read this:

yes there is an easy way to just punch the old ones in and install a rubber freeze plug repair kit. But, how long do you want it to last?

I installed some of those rubber ones about 15 years ago on the original mill. they're still there and not leaking.

straight to the point... throw a couple extra in the glove box, and if the ones installed start leaking, change it again. Its not worth pulling the engine for that fix unless it becomes a bigger or consistent problem. Its all a personal preference.
