How did you get it home? Did you drive it without coolant?

 

[24Carrot]

No relay

 

[ukadamwest]

That'll be a yes then !

 

[Druim]

Better find the socket set

That was ment to say rely not relay as in AA rely

You were right first time, it's AA relay

So if it is smokes from the header tank .then is it head gasket? Or something worse?

 

[Datatek]

Starting it with no water in it is a good way to destroy the engine. You sure it's exhaust and not steam coming out of the expansion tank, because with virtually no water it will make steam quicker than an electric kettle.

I know not to let it run for long with out water.
It started smoking within 30 sec to a min
And then I turned it off

 

[tomcat59alan]

Mm, heads pressure tested, skimmed, and new gaskets

 

[24Carrot]

If that's it I get on and do it .but what I want to know is .is it more likely to be a dropped liner. Or a cracked block. And is there a way to tell

 

[tomcat59alan]

Yup, take it to pieces

 

[24Carrot]

Sorry are you saying taking it apart is the only way to tell .or take it apart to do the head gasket

Which it would do with next to no water in the heads and antifreeze stinks when burnt.
Fill it with water and bleed it and try again, see if the hoses pressurise.

 

[24Carrot]

OK .but just had a look and took the rocker cap of .and there is sine of water in the oil 😢

 

[24Carrot]

But is there anyway I can tell if it's a liner? Or a cracked block

 

[marccleave]

Yup, take it to pieces

.

 

[24Carrot]

So are all the symptoms the same?
