I would say that it is 99 % certain that the head gasket has gone  Sad
If your rocker cover breather cap looks like

Then a good chance that the head gasket has gone { Note though that you can get mild examples of that through the engine not being used for a long time and /or very short journeys }
But if when you remove the rocker cover you have the following , then it probably has gone to the great bust head gasket home in the sky

Note the black rubber sealant left by a previous owner using it to seal the rocker cover ; All you need is grease .

.
A warning sign of a poor previous head gasket change is any RED or Blue  stuff around the cylinder head join . You do not need to use any sealant whatsoever

The cylinder head can be assisted in removal by using the flat plate cylinder head removal tool

Fifer...yep all of the above but not so much mayo on the rockers! Grin I will be phoning you in the next couple of days...
Hunter...I know it would be cheaper to do that,but bearing in mind this engine came from a running mot'd car.............. Roll Eyes
 
 So,a bit of progress up to today..engine now stripped of all ancillaries/unbolted from frame etc,awaiting extraction tomorrow night!
 Will strip the rest of it ,clean all the ancillaries etc over the w/end
 Im intending to take it to the engine people on Monday pm.

Thats a generous offer mate,but depending of course what they find at the engineering place,by the time Ive collected yours etc ,I may as well get mine done.Thanks very much anyway.

These were 2 separate engines and believe it or not the one with the gunge in the Alloy rocker cover , since someone else had recently changed the head because it was porous I just tightened the head down correctly { the bolts were only between 10 and 15 } , drained , flushed and refilled the coolant , drained and changed the oil and it has been running like a wee sweety for the last six months { Owner was a lucky person who works behind a bar  Grin}

 Found the problem! No1 piston has a lump out of it! As you look down on the piston ,about 25mm of the outer diameter of the piston to a depth of the top ring! The gasket seems ok,but must have been leaking at that point.No1 chamber in the head is mayo'd,but not the rest.Anyway,the lump that has broke off has caused the wall of the bore to be really badly scored etc. May get away with a re bore on that pot only,as the others look in vg cond with no ridge at the top of the bore etc.

if its scored its best to fit a full set of liners

false economy boring one pot

another option is to get another block to rebuild

i can take the head of the spare engine in the shed and see how good that block is if you want  it could workout a lot cheaper  Wink Wink

So,with these engines ,do they automatically replace the liners when reboring? Is replacing them going to be costly?
 
 Been looking around,seen a couple of engines, The one on flea bay may sound ok,but Im a bit dubious about the heritage/history of stuff like this! Think Ive got to take it to the engineers and see what they say,at least then Ill know the cost.PLUS of course,Im looking for a quick turn around.
Arrggh!

Brand new set of 4 pistons / liners straight from Reliant
£220 plus £10 postage
http://www.ebay.co.uk/itm/Reliant-Robin-Rialto-Piston-Liner-Kits-850cc-750cc-/180595846658?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2a0c59ee02

and they might find it could do with new mains / big end shells { up to £130 }
New engine gasket set around £45
New valve springs ?
Check the valves ?
£50 drop in replacement engine or bottom end looks good to me { But then what more do you expect from  a Scotsman  Grin Grin Grin  }
You can then get the original engine rebuilt at your leisure as you zoom around on the trike .
