Some threads earlier I asked about size of bastard bolt as up to now coolant transfer pipe was held on its place only by praying. After I moved it a bit major coolant leak appeared  tomorrow I'm gonna give it a go but before starting the operation I would like to know if a double O ring swap was enough or I should get some extra glue, too?   

TIA

O rings only,you might get a away with it,or buy the transfer pipe with o rings as you may damage it getting it out.

Not being bolted to the block can potentially allow it to come adrift under pressure

Inspect the stat housing while you're at it. Too much corrosion in there and it won't seal in a month of Sunday's.

Laszlo, have you changed the thermostat recently iirc, someone out that way has done in the last month or so...

Yep, you remember well, have done it without touching the bastard bolt, at the time it seemed possible didn't pay enough attention to the bolt    I haven't noticed the lack of bolt at all till yesterday. How didn't appear when I was doing that connecting the stat and transfer pipe was quite easy...?

The missing bolt probably made it alot easier

Replace the bolt and all should be well corrosion not a real issue with the new thermostat casing as the transfer pipe plugs into it

Sorted out Al!  O rings changed, B bolt replaced, no leaking , possible radiator coolant pipe swap will be in the close future as it looks not too good condition.  Thanks a lot , guys!
