Lower Engine Plugs
Hi,
here is another try with the pictures this time, sorry for that.
I had a cooling liquid leak underneath the engine. The leak came from a big hole on the lower part of the engine block (see picture).
This hole was pluged with a rubber ring (see pictures)
The rubber is dry and cracked, this caused the leak. It seems that this plug is not an original built, because I haven't see or read on the corvette litterature about such rubber plug.
Why is this big hole for? have you the same rubber plug on your vet? how can I definitly plug this hole? where can I get a replacement plug, I coudn't find anything by corvette central (how is this thing called).
Thank for you help
Mike

Re: Lower Engine Plugs (mpeter)
can't see pic. but some people use a( rubber) expanding freeze(core) plug
to replace a leaky one .... easier not better :nono: i've used a lot of them
on different car's because of time and people didn't have the money to do it
correctly, is it hard to get to?

What you re reffering to is called a frost plug or welch plug. And as Comp explained that sometimes for ease of installation some people will put a rubber one in.
The hole is the block has no pupose other than it had to be there when they cast the block. From the factory it would have had a metal plug in it the same as the other one on your picture. You can get one at any parts house that sells engine parts. They are not just for a Corvette. They are the same on any small block chevy engine and many other engines besides that. And are very inexpensive (under $1.00).
To install them you put a light coat of sealer around the outer edge of the plug and use a drift punch about the size of the cup on the plug to hammer them in, being careful not to drive them too far in. (Make sure the hole in the block is good and clean first)
