Freeze plugs I guess are designed to pop out to prevent a block freezing and
I guess are easy to replace if you got access to the plug. I have seen
rubber ones that expand with a bolt. I would not trust a quick fix
especially if you do a lot of travelling in your boat away from help if
needed. I am assuming you have the Buick V6 in your boat. My 69 V6 has a
petcock on an extension from the lower block on each side making for easier
access when draining the block. They use a standard brass or steel pipe with
tapered pipe threads. I believe but do not quote me on that. You may just
have to retighten that fitting. You may otherwise have some block damage and
will really need to get a mechanic to check it out. The first few times you
run it be real sure you are not getting water in the oil. That can happen
with a cracked block and leads to more problems. You can use JB Weld to
repair low pressure water leaks on the outside of the block but that is thin
ice IMHO. You can run a leaking engine as long as your bilge pump keeps up.
Good luck. Here is hoping that the repairs are minor and easily done.

Hello -

Getting my '68 out this spring I have a new problem ... looks like the
block didn't get drained completely and things froze up a bit.

On the port side I have water coming out of the size of the block. I can't
easily see the location, but my fingers tell me it's coming from a largish
round hole which I assume to be a freeze plug. I'm assuming this can be
'fixed' using the standard automotive repairs. If someone knows otherwise,
please tell me.

On the starboard side however I have what feels like a different issue.
Again I can't easilly see the source of the water, but it feels like there
is a fitting with a stem with a valve on the end of it coming from the side
of the block. Water seems to be coming (spraying) from the base of the
stem or the block where the stem attaches to the block. First ...does
anybody know what this thing is? and second, does anybody have any
thoughts on what the likely repair path is going to be for this?

My sense is that to gain access I'm going to have to remove the exhaust
manifolds and I'm wondering how much tear-down I'm going to be getting into
and what parts availability for things like gaskets is going to be like.

I'm located in Denver, CO if anybody has any advise relating to parts
sources or mechanics who are good with these older powerplants.

Thanks,

Kenneth
