Hi everyone!
I think ive blown a frost plug in my 1800 as water is flowing out the back of engine through a hole I can feel with my finger. ...but can't see.
I can't find a reference to any frost plug in my marina manual?
Any help would be appreciated

Re: frost plug
It is commonly known as a core plug, you can get new ones from MGBHive or most MGB specialists 
Re: frost plug
Yep there is one at the back-need to remove the gearbox and back plate to replace it.
Can be done with engine in place but not easy.
Might wise to 'strap' the new one in.
