Thread: 390 water leak @ freeze plug

Tweet

It looks like my 390 engine in my 63 Galaxie is leaking water on the drivers side freeze plug. It looks like it is coming from the freeze plug area but could it be a cracked block? I have not put it on jack stands yet to get a real good look at it but the leak worries me.
Are these engines subject to cracking in this area? The car has been a Georgia/Florida car for the last 10 years.
The engine has been rebuilt it looks like about 5 years ago.

Sorry for the rambling just hopeful that the engine is ok.

Thanks Rod

Cannot say they are subject to cracking, more like a poor seal at a freeze plug. Replace it and see if there is still a leak present.

Most likely a rotted out freeze plug. When you are replacing them go to brass ones, they will outlive you.

I agree 100%. Steel plugs rot out after time. Hopefully that's the case.They do sell those expandable rubber plugs you can use as a quick repair. To see then if it still leaks. As far as a crack goes it's possible. Is there antifreeze in it? What mix? Has it had a chance to freeze? I know your in the south but there has been colds snaps everywhere at times. The Galaxie should have enough room to easily fix and get at it.
